While previous research has identified correlations between the use of voice assistants and trust in these technologies, as well as data security concerns, little evidence exists regarding the relationship between individual user traits and perceived trust and security concerns. The study design involves surveying various user attributes, including technical proficiency, personality traits, and experience with digital technologies, alongside attitudes toward and usage of voice assistants. A comparison between Germany and Finland is conducted to explore potential cultural differences. The findings aim to inform strategies for enhancing voice assistant acceptance, including the implementation of anonymization methods.}, url = {https://aclanthology.org/2024.legal-1.11} }

This paper explores the underutilization of Voice User Interfaces (VUIs) among individuals with disabilities, particularly those with mental disabilities. Drawing from Smith and Smith's [40] emphasis on inclusive co-design, we advocate for involving individuals with disabilities as well as including domain experts in the development of VUIs from the outset.

`AI and Educational Sciences Seminar'' at the Otto-von-Guericke-Universit{\}a}t Magdeburg (OVGU) serves as a practical exploration ground, engaging educational sciences students in developing an inclusive Alexa Skill for a diverse user group.

Hereby, above all, the user’s speech data is stored and processed on a cloud platform, being the decisive factor for a good performance in speech processing and understanding. Although usually, they can be found in private households, a lot of business cases are also employed using voice assistants for public places, be it as an information service, a tour guide, or a booking system. As long as the systems are used in private spaces, it could be argued that the usage is voluntary and that the user itself is responsible for what is processed by the voice assistant system. When leaving the private space, the voluntary use is not the case anymore, as users may be made aware that their voice is processed in the cloud and background voices can be unintendedly recorded and processed as well. Thus, the usage of voice assistants in public environments raises a lot of privacy concerns. In this contribution, we discuss possible anonymization solutions to hide the speakers’ identity, thus allowing a safe cloud processing of speech data. Thereby, we promote the public use of voice assistants.}, url = {https://aclanthology.org/2022.legal-1.8} }

HCII 2022}, year={2022}, publisher={Springer International Publishing}, address={Cham}, abstract={In order to relax in everyday life, people use music from a sound carrier. The choice of music is made intuitively and according to one’s musical preference. In a therapeutic context, these processes are professionally guided. In so-called receptive music therapy, the patient and therapist listen to music together. The psychological processes triggered by this (e.g. imaginations, memories) are worked through in therapeutic conversation. But professional music therapy is not always feasible, as getting an appointment could take some time, the need for receptive music therapy is urgent at the time the treatment is not available, etc. Furthermore, voice assistants are increasingly dominating everyday life and represent an easy way to perform various tasks with minimal effort. The areas of application for voice assistants are diverse and range from answering simple information questions to processing complex topics and controlling various tasks. Given these considerations of the wide availability and ease of use, a pilot study was designed to combine the effective approaches of music therapy with modern voice assistants. The study entails one interaction with an Alexa Skill allowing a music-imaginative journey in an interactive manner, and a control condition without interactive parts using a CD. 21 participants took part in the study, of which first analyses are presented in the paper. Especially results regarding the analyses of the user experience (AttrakDiff and meCUE) as well as a discussion of the subjective participants’ reflections on the interaction regarding the limitations of commercial voice assistants are presented}, isbn={978-3-031-05014-5}, doi={10.1007/978-3-031-05014-5_29}, keywords={conferencebook,conference} }

Furthermore a companion system allows a naturalistic human-computer interaction. The dissertation discussed in this article investigates improvements for natural speech-based interaction in the example of four open issues. These issues should be resolved to allow future systems to act like a companion system.
As first open issue, methodological improvements for the annotation of emotions as well as studies of inter-rater reliability to evaluate emotions are examined. The second open issue analyses how speaker-group-dependent models can improve the emotion recognition. This allows companion systems to respond in an individual way to a user, although no adaptation for the specific user has been conducted. The third open issue deals with so-called discourse particles and analyses if they have the same functional meanings in human-computer interaction as in human to human communication. Furthermore, it is investigated if this meaning could be distinguished by the pitch contour. In the fourth open issue, the user's long-term emotional development is modelled by using a physically inspired spring model. Additionally, the integration of the user's personality trait extraversion is discussed.
The incorporation of the methods discussed in relation with the investigated four open issues allow companion systems to behave more like a human interlocutor. The discussed thesis especially points towards possibilities to implement an adaptive and individual companion system.}, keywords={zeitung} }

This further information is effectively transmitted by semantic and prosodic cues, without interrupting the speaker. For the German language we rely on previous empirically discovered seven types of form-function-concurrences on the isolated discourse particle (DP) “hm”.
In this paper we present an improved automatic classification-method towards non-isolated DPs in human-human interaction (HHI). We show that classifiers trained on (HCI)-data can be used to robustly evaluate the contours of DPs in both HCI and HHI by performing a classifier adaptation to HHI data. We also discuss the problem of the pitch-contour extraction due to the unvoiced “hm”-utterances, leading to gaps and/or jumps in the signal and hence to confusions in form-type classifications. This can be alleviated by our investigation of contours with high extraction completion grade. We also show that for the acoustical evaluation of the functional-meaning, the idealized form-function prototypes by Schmidt are not suitable in case of naturalistic HHI. However, the precision of acoustical-meaning prediction with our classifier remains high. }, keywords={conferencebook,conference} }

Moreover, the subjects analyzed in both interaction types are not the same and thus, direct connections could not be made.
In our contribution, we report about analyses of discourse particles in both HHI and HCI with the same subjects.

In the current paper we analysed the relation between different normalisation methods for emotionally coloured speech samples deriving general trends to be considered during data pre-processing. From the best of our knowledge, various normalisation approaches are used in the spoken affect recognition community but so far no multi-corpus comparison was conducted. Therefore, well-known methods from literature were compared in a larger study based on nine benchmark corpora, where within each data set a leave-one-speaker-out validation strategy was applied. As normalisation approaches, we investigated standardisation, range normalisation, and centering. These were tested in two possible options: (1) The normalisation parameters were estimated on the whole data set and (2) we obtained the parameters by using emotionally neutral samples only. For classification Support Vector Machines with linear and polynomial kernels as well as Random Forest were used as representatives of classifiers handling input material in different ways. Besides further recommendations we showed that standardisation leads to a significant improvement of the recognition performance. It is also discussed when and how to apply normalisation methods.}, isbn={978-3-319-72038-8}, doi={10.1007/978-3-319-72038-8_15}, url={https://doi.org/10.1007/978-3-319-72038-8_15}, keywords={conferencebook,conference} }

A lot of development was made to guarantee a high speech intelligibility resulting in different compression techniques: Analysis-by-Synthesis, psychoacoustic modeling and a hybrid mode of both. Our first assumption is that the hybrid mode improves the speech intelligibility. But, enabling a natural spoken conversation also requires affective, namely emotional, information, contained in spoken language, to be intelligibly transmitted. Usually, compression methods are avoided for emotion recognition problems, as it is feared that compression degrades the acoustic characteristics needed for an accurate recognition [1]. By contrast, in our second assumption we state that the combination of psychoacoustic modeling and Analysis-by-Synthesis codecs could actually improve speech-based emotion recognition by removing certain parts of the acoustic signal that are considered ``unnecessary'', while still containing the full emotional information. To test both assumptions, we conducted an ITU-recommended POLQA measuring as well as several emotion recognition experiments employing two different datasets to verify the generality of this assumption. We compared our results on the hybrid mode with Analysis-by-Synthesis-only and psychoacoustic modeling-only codecs. The hybrid mode does not show remarkable differences regarding the speech intelligibility, but it outperforms all other compression settings in the multi-class emotion recognition experiments and achieves even an {\$}{\$}{\backslash}sim {\$}{\$} 3.3{\%} absolute higher performance than the uncompressed samples.}, isbn={978-3-319-66429-3}, doi={10.1007/978-3-319-66429-3_44}, url={https://doi.org/10.1007/978-3-319-66429-3_44}, keywords={conferencebook,conference} }

In a previous perceptual study on Opus-processed 5.1 surround sound, uncompressed and degraded stimuli were rated on a five-point degradation category scale (DMOS) for six channels at total bitrates between 96 and 192 kbit/s.

This tool relies on established emotion labelling methods, like the Geneva Emotion Wheel or the Self Assessment Manikins to maintain the relationship. Furthermore, the annotator is guided by a step-wise process to improve the reliability of the emotional annotation. Additionally, the uncertainty in assessing emotions can be covered as well, to evaluate the labels afterwards and exclude samples with to low uncertainty from further analyses.

As most current corpora do not supply enough material, a combination of different datasets is advisable. Unfortunately, data recording is done differently and various emotion elicitation and emotion annotation methods are used. Therefore, a combination of corpora is usually not possible without further effort. The manuscript’s aim is to answer the question which corpora are similar enough to jointly be used as training material. A corpus similarity measure based on PCA-ranked features is presented and similar datasets are identified. To evaluate our method we used nine well-known benchmark corpora and automatically identified a sub-set of six most similar datasets. To test that the identified most similar six datasets influence the classification performance, we conducted several cross-corpora emotion recognition experiments comparing our identified six most similar datasets with other combinations. Our most similar sub-set outperforms all other combinations of corpora, the combination of all nine datasets as well as feature normalization techniques. Also influencing side-effects on the recognition rate were excluded. Finally, the predictive power of our measure is shown: increasing similarity score, expressing decreasing similarity, result in decreasing recognition rates. Thus, our similarity measure answers the question which corpora should be included into joint training.} }

A sound and speech signal processing at UAVs is complex because of rotor and maneuver-related noise components. The signal processing has to consider various sound sources, and the wanted signals (e.g. artificial environmental noise or speech signals) have to be separated from the UAVs' own flight and wind noise. The contribution discusses the acoustic scenarios and some acoustic characteristics of a sample UAV, including the effect of flight maneuvers. We recorded speech signals in best practice with regard to the outcome of our preliminary analyses and then conducted objective speech quality measurements and speech recognition experiments with a state-of-the-art recognizer.

Thereby, the development benefits mostly from the rapidly increased cloud-based speech recognition systems. Furthermore many cloud-based services, such as Google Speech API, IBM Watson, and Wit.ai, can be used for personal applications and transcription tasks. As these tasks vary in their domain, their complexity as well as in their interlocutor, it is challenging to select a suitable cloud-based speech recognition service. As the update-process of online-services can be completely handled in the back-end, client applications do not need to be updated and thus improved accuracies can be expected within certain periods. This paper contributes to the field of automatic speech recognition, by comparing the performance of speech recognition between the above-mentioned cloud-based systems on German samples of high-qualitative spontaneous human-directed and device-directed speech as well as noisy device-directed speech over a period of eight months.}, isbn={978-3-030-60276-5}, keywords={conferencebook,conference} }

Up to now around 40 hours of device directed utterances were collected during a science exhibition touring through Germany. The data recording was part of an exhibit that engages visitors to interact with a commercial voice assistant system (Amazon’s ALEXA), but did not restrict them to a specific topic. A specifically developed quiz was starting point of the conversation, as the voice assistant was presented to the visitors as a possible joker for the quiz. But the visitors were not forced to solve the quiz with the help of the voice assistant and thus many visitors had an open conversation. The provided dataset – Voice Assistant Conversations in the wild (VACW) – includes the transcripts of both visitors requests and Alexa answers, identified topics and sessions as well as acoustic characteristics automatically extractable from the visitors’ audio files.}, url = {https://aclanthology.org/2020.lrec-1.77/}, keywords={conferencebook,conference} }

Typically, wake words are used. But these force an unnatural interaction and are error-prone, especially in case of false positive classification (user says the wake up word without intending to interact with the device). Therefore, technical systems should be enabled to perform a detection of device directed speech. In order to enrich research in the field of speech analysis in HCI we conducted studies with a commercial voice assistant, Amazon's ALEXA (Voice Assistant Conversation Corpus, VACC), and complemented objective speech analysis with subjective self and external reports on possible differences in speaking with the voice assistant compared to speaking with another person. The analysis revealed a set of specific features for device directed speech.

abstract={Remote meetings via Zoom, Skype, or Teams limit the range and richness of nonverbal communication signals. Not just because of the typically sub-optimal light, posture, and gaze conditions, but also because of the reduced speaker visibility. Consequently, the speaker’s voice becomes immensely important, especially when it comes to being persuasive and conveying charismatic attributes. However, to offer a reliable service and limit the transmission bandwidth, remote meeting tools heavily rely on signal compression. It has never been analyzed how this compression affects a speaker’s persuasive and overall charismatic impact. Our study addresses this gap for the audio signal. A perception experiment was carried out in which listeners rated short stimulus utterances with systematically varied compression rates and techniques. The scalar ratings concerned a set of charismatic speaker attributes. Results show that the applied audio compression significantly influences the assessment of a speaker’s charismatic impact and that, particularly female speakers seem to be systematically disadvantaged by audio compression rates and techniques. Their charismatic impact decreases over a larger range of different codecs; and this decrease is additionally also more strongly pronounced than for male speakers. We discuss these findings with respect to two possible explanations. The first explanation is signal-based: audio compression codecs could be generally optimized for male speech and, thus, degrade female speech more (particularly in terms of charisma-associated features). Alternatively, the explanation is in the ears of the listeners who are less forgiving of signal degradation when rating female speakers’ charisma.}, keywords={zeitung} }@Inproceedings{SiegertNiebuhrESSV:2021, Title = {Speech Signal Compression Deteriorates Acoustic Cues to Perceived Speaker Charisma}, Address = {Berlin, Germany}, Author = {Siegert, Ingo and Niebuhr, Oliver}, Booktitle = {Elektronische Sprachsignalverarbeitung 2021.

Especially, intentional and emotional characteristics are essential to improve not only the relationship in a human-human interaction, but also to provide benefits to increase the understanding of the transmitted information. For technical systems it is favourable to detect and interpret these additional characteristics and to transfer appropriate knowledge to human-machine interactions. In particular, this enables an automatic recognition of emotions. In this paper, we focus on speech as the transmitting modality. Beyond the detection of the location and nature of emotional instances, automatic interpretation asks "if", "how", and "when" emotions change in an interaction. In the EmoGest corpus, providing human-human interactions with emotionally induced subjects, we analyse the subject's emotional evolution. For this, we investigate the utterances spoken at the beginning and at the end of particular sessions. Automatic emotion recognition from speech shows that in intra- and inter-individual evaluations, significant differences (at least p<0.05) in the emotional state train of the subjects can be detected. Intra-individual experiments indicate a trend towards less affective states in subsequent interactions if no further inducement is given. In addition, the inter-individual analyses show that a kind of alignment can be seen in the emotional state trains of the single subjects even if their sessions were strictly separated. }, keywords={conferenceproc,conference} }

Further, this enables us to present a method for automatic identification of groups of corpora with similar characteristics. This answers an urgent question in classifier development, namely whether data from different corpora is similar enough to jointly be used as training material, overcoming shortage of material in matching domains.

Abstract = { For a successful speech-controlled human-computer interaction (HCI) the pure textual information as well as individual skills, preferences, and affective states of the user have to be known. However, verbal human interaction consists of several information layers. Apart from pure textual information, further details regarding the speaker’s feelings, believes, and social relations are transmitted. The additional information is encoded through acoustics. Especially, the intonation reveals details about the speakers communicative relation and their attitude towards the ongoing dialogue.
Since the intonation is influenced by semantic and grammatical information, it is advisable to investigate the intonation of so-called discourse particles (DPs) as “hm” or “uhm”. They cannot be inflected but can be emphasised. DPs have the same intonation curves (pitch-contours) as whole sentences and thus may indicate the same functional meanings. For German language J. E. Schmidt empirically discovered seven types of form-function-concurrences on the isolated DP “hm”.
To determine the function within the dialogue of the DPs, methods are needed that preserve pitch-contours and are feasible to assign defined form-prototypes. Furthermore, it must be investigated which pitch-contours occur in naturalistic HCI and whether these contours are congruent with the findings by linguists.
In this paper we present first results on the extraction and correlation of the DP “hm”. We investigate the different form-function-relations in the naturalistic LAST MINUTE corpus and determine expectable form-function relations in naturalistic HCI in general.

These short feedback signals minimally communicate certain dialogue functions such as attention, understanding or other attitudinal reactions. Human-computer interaction (HCI) systems have failed to note and respond to these details so far, resulting in users trying to cope with and adapt to the machines behaviour. In order to enhance HCI, an adaptation to the user’s behaviour, individual skills, and the integration of a general human behaviour understanding is indispensable. Another issue is the question if the usage of feedback signals is influenced by the user’s individuality. In this paper, we investigate the influence of specific feedback signals, known as discourse particles (DPs), with communication style and psychological characteristics within a naturalistic HCI.

For this reason, naturalistic material is recorded, where the subjects are guided through an interaction with crucial points, but with the freedom to react individually. This material captures realistic user reactions but lacks of clear labels. So, a good transcription and annotation of the given material is essential. For that, the assignment of human annotators has become widely accepted. A good measurement for the reliability of labelled material is the inter-rater agreement. In this paper we investigate the achieved inter-rater agreement utilizing Krippendorff’s alpha for emotional annotated interaction corpora and present methods to improve the reliability, we show that the reliabilities obtained with different methods does not differ much, so a choice could rely on other aspects.

We found indications that younger subjects prefer a more technical style in communication with dialog systems. Next, we model the subject’s internal success state with a hidden Markov model trained using the observed sequences of system feedback. This reveals that younger subjects interact significantly more successful with technical systems.

We use both acoustic and linguistic features to build several trait-specific classifiers for dialog phases, which showed pronouncedly different accuracies for diverse age and gender groups.

Especially speech provides a high information density, delivering information about the speaker's inner state as well as his intention and demand. While word-based analyses allow to understand the speaker's request, further speech characteristics reveal the speakers emotion, intention and motivation. Therefore, emotion detection from speech became signicant in modern HCI applications. However, the results from the disciplines involved in the emotion detection are not easily merged. Engineers developing voice controlled HCI systems work in feature spaces", relying on technically measurable acoustic and spectral features. Psychologists analysing and identifying emotions work in emotion categories, schemes or dimensional emotion spaces, describing emotions in terms of quantities and qualities of human notable expressions. While engineering methods notice the slightest variations in speech, emotion theories allow to compare and identify emotions, but must rely on human judgements. However, both perceptions are essential and must be combined to allow machines to allocate aective states during HCI. To provide a link between machine measurable variations in emotional speech and dimensional emotion theory, signicant features describing emotions must be identied and analysed regarding their transferability to emotion space.

In human-human interaction (HHI) the behaviour of the speaker is characterised by semantic and prosodic cues, given as short feedback signals. These signals minimally communicate certain dialogue functions such as attention, understanding, confirmation, or other attitudinal reactions. Thus, these signals play an important role in the progress and coordination of interaction. They allow the partners to inform each other of their behavioural or affective state without interrupting the ongoing dialogue. Vocal communication provides acoustic details revealing the speaker’s feelings, believes, and social relations. Incorporating discourse particles (DPs) in human-computer interaction (HCI) systems will allow the detection of complex emotions, which are currently hard to access. Complex emotions in turn are closely related to human behaviour. Hence, integrating automatic DP detection and complex emotion assignment in HCI systems provides a first approach to the integration of human behaviour understanding in HCI systems. In this paper we present methods allowing to extract the pitch-contour of DPs and to assign complex emotions to observed DPs. We investigate the occurrences of DPs in naturalistic HCI and show that DPs may be assigned to complex emotions automatically. Furthermore, we show that DPs are indeed related to behaviour, showing an age-gender specific usage during naturalistic HCI. Additionally, we prove that DPs may be used to automatically detect and classify complex emotions during HCI. }, url ={pdf/2013_hbu_preprint.pdf}, keywords={conferencebook,conference} }

By incorporating emotion recognition, applications such as monitoring agents or digital companions can be improved. The recognition result is used to model the state of the user. This leads to an adaptive reaction of the system towards users needs and claims and thus to an enhanced system reaction. Besides emotions, based on short events, personality and moods also play an important role. Standard emotion recogniser do not consider them adequately and therefore neglect a crucial part of user modelling. The challenge is to gather a reliable prediction about the actual mood of the user and moreover represent changes in users' mood during interaction. This includes both the different user-dispositions and the observation of the inner user-state. Therefore conclusions from external conditions has to be drawn. For this we suggest a model with few parameters that, based on a prevailing mood represents the actual mood of an user. Thereby recognised emotions are modelled as forces, appealing on the mood and shifting it within the VAD-space. Additionally by implementing a repulsing force a decaying mood can be modelled. Thereby it is possible to simulate the short-time effects and the volatility of emotions and also the slow and continuous development of moods. Furthermore the model is able to incorporate different traits of personality. The prevailing mood, representing a certain user-disposition, will be shifted within the VAD-space. In Addition, recognised emotions are assigned to different forces, by what external observations according to personality-traits can represent different inner user-states.}, url ={pdf/2011_icme_preprint.pdf}, keywords={conferenceproc,conference} }
