  1. Trained and optimized for typical and fluent speech, speech AI works poorly for people with speech diversities, often interrupting them and misinterpreting their speech. The increasing deployment of speech AI in automated phone menus, AI-conducted job interviews, and everyday devices poses tangible risks to people with speech diversities. To mitigate these risks, this workshop aims to build a multidisciplinary coalition and set the research agenda for fair and accessible speech AI. Bringing together a broad group of academics and practitioners with diverse perspectives, including HCI, AI, and other relevant fields such as disability studies, speech language pathology, and law, this workshop will establish a shared understanding of the technical challenges for fair and accessible speech AI, as well as its ramifications in design, user experience, policy, and society. In addition, the workshop will invite and highlight first-person accounts from people with speech diversities, facilitating direct dialogues and collaboration between speech AI developers and the impacted communities. The key outcomes of this workshop include a summary paper that synthesizes our learnings and outlines the roadmap for improving speech AI for people with speech diversities, as well as a community of scholars, practitioners, activists, and policy makers interested in driving progress in this domain.

  2. Live TV news and interviews often include multiple individuals speaking, with rapid turn-taking, which makes it difficult for viewers who are Deaf and Hard of Hearing (DHH) to follow who is speaking when reading captions. Prior research has proposed several methods of indicating who is speaking. While recent studies have observed various preferences among DHHviewers for speaker identification methods for videos with different numbers of speakers onscreen, there has not yet been a study that has systematically explored whether there is a formal relationship between the number of people onscreen and the preferences among DHH viewers for how to indicate the speaker in captions.We conducted an empirical study followed by a semi-structured interview with 17 DHH participants to record their preferences among various speaker-identifier types for videos that vary in the number of speakers onscreen. We observed an interaction effect between DHH viewers’ preference for speaker identification and the number of speakers in a video. An analysis of open-ended feedback from participants revealed several factors that influenced their preferences. Our findings guide broadcasters and captioners in selecting speaker-identification methods for captioned videos.

    Deaf and hard of hearing (DHH) viewers watch multimedia with captions on devices with widely varying widths. We investigated the impact of caption width on viewers' preferences. Previous research has shown that presenting one word lines allows viewers to read much more quickly than traditional reading, while others have shown that the optimal width for captions is 6 words per line. Our study showed that DHH viewers had no preference difference between 6 and 12 word lines. Furthermore, they significantly preferred 6 and 12 word lines over single word lines due to the need to split attention between the captions and video.

    In this experience report, we describe the accessibility challenges that deaf and hard of hearing users face in teleconferences, based on both our first-hand participation in meetings, and as User Interface and Experience experts. Teleconferencing poses new accessibility challenges compared to face-to-face communication because of limited social, emotional, and haptic feedback. Above all, teleconferencing participants and organizers need to be flexible, because deaf or hard of hearing people have diverse communication preferences. We explain what recurring problems users experience, where current teleconferencing software falls short, and how to address these shortcomings. We offer specific recommendations for best practices and the experiential reasons behind them.

  5. Developing successful sign language recognition, generation, and translation systems requires expertise in a wide range of fields, including computer vision, computer graphics, natural language processing, human-computer interaction, linguistics, and Deaf culture. Despite the need for deep interdisciplinary knowledge, existing research occurs in separate disciplinary silos, and tackles separate portions of the sign language processing pipeline. This leads to three key questions: 1) What does an interdisciplinary view of the current landscape reveal? 2) What are the biggest challenges facing the field? and 3) What are the calls to action for people working in the field? To help answer these questions, we brought together a diverse group of experts for a two-day workshop. This paper presents the results of that interdisciplinary workshop, providing key background that is often overlooked by computer scientists, a review of the state-of-the-art, a set of pressing challenges, and a call to action for the research community.
