- Speech interfaces are growing in popularity. Through a review of 99 research papers this work maps the trends, themes, findings and methods of empirical research on speech interfaces in the field of human-computer interaction (HCI). We find that studies are usability/theory-focused or explore wider system experiences, evaluating Wizard of Oz, prototypes or developed systems. Measuring task and interaction was common, as was using self-report questionnaires to measure concepts like usability and user attitudes. A thematic analysis of the research found that speech HCI work focuses on nine key topics: system speech production, design insight, modality comparison, experiences with interactive voice response systems, assistive technology and accessibility, user speech production, using speech technology for development, peoples' experiences with intelligent personal assistants and how user memory affects speech interface interaction. From these insights we identify gaps and challenges in speech research, notably taking into account technological advancements, the need to develop theories of speech interface interaction, grow critical mass in this domain, increase design work and expand research from single to multiple user interaction contexts so as to reflect current use contexts. We also highlight the need to improve measure reliability, validity and consistency, in the wild deployment and reduce barriers to building fully functional speech interfaces for research.

Introducing AmuS : The Amused Speech Database
- 2017
-
Konferensbidrag (refereegranskat)abstract
- In this paper we present the AmuS database of about three hours worth of data related to amused speech recorded from two males and one female subjects and contains data in two languages French and English. We review previous work on smiled speech and speech-laughs. We describe acoustic analysis on part of our database, and a perception test comparing speech-laughs with smiled and neutral speech. We show the efficiency of the data in AmuS for synthesis of amused speech by training HMM-based models for neutral and smiled speech for each voice and comparing them using an on-line CMOS test.

Between and within speaker transitions in multiparty conversation
- 2020
-
Ingår i: Proceedings of Speech Prosody. ; , s. 799-803
-
Konferensbidrag (refereegranskat)abstract
- Casual conversation proceeds as a series of contributions from participants, either speaking in the clear or in overlap. The pattern of who is speaking or not (the conversational floor state) changes constantly throughout a conversation. We examine the nature and frequency of these state changes or transitions in multiparty talk, which may involve more complicated floor state transitions than dyadic interactions. We contrast within and between speaker transitions, analyzing the evolution of the conversational floor state from a stretch of single party speech in the clear to the next stretch of single party speech in the clear by the original or a different speaker. We investigate the effect of applying a minimum duration of single party speech in the clear to the incoming speaker’s production, finding substantial differences in how transitions are categorized. Over 40\% of the transitions categorized as between or within speaker change category depending on whether a minimum duration is applied to the following stretch of single party speech.

Speaker transition patterns in three-party conversation : Evidence from English, Estonian and Swedish
- 2021
-
Ingår i: Proceedings of Interspeech 2021.
-
Konferensbidrag (refereegranskat)abstract
- During conversation, speakers hold and relinquish the floor, resulting in turn yield and retention. We examine these phenomena in three-party conversations in English, Swedish, and Estonian. We define within- and between-speaker transitions in terms of shorter intervals of speech, silence and overlap bounded by stretches of one-party speech longer than 1 second by the same or different speakers. This method gives us insights into how turn change and retention proceed, revealing that the majority of speaker transitions are more complex and involve more intermediate activity than a single silence or overlap. We examine the composition of within and between transitions in terms of number of speakers involved, incidence and proportion of solo speech, silence and overlap. We derive the most common within- and between-speaker transitions in the three languages, finding evidence of striking commonalities in how the floor is managed. Our findings suggest that current models of turn-taking used in dialogue technology could be extended using these results to more accurately reflect the realities of human-human dialogue.
