Stifelman, Lisa, Arons, Barry and Schmandt, Chris (2001): The Audio Notebook: Paper and Pen Interaction with Structured Speech. In: Beaudouin-Lafon, Michel and Jacob, Robert J. K. (eds.) Proceedings of the ACM CHI 2001 Human Factors in Computing Systems Conference March 31 - April 5, 2001, Seattle, Washington, USA. pp. 182-189. Available online

“This paper addresses the problem that a listener experiences when attempting to capture information presented during a lecture, meeting, or interview. Listeners must divide their attention between the talker and their notetaking activity. We propose a new device-the Audio Notebook-for taking notes and interacting with a speech recording. The Audio Notebook is a combination of a digital audio recorder and paper notebook, all in one device. Audio recordings are structured using two techniques: user structuring based on notetaking activity, and acoustic structuring based on a talker's changes in pitch, pausing, and energy. A field study showed that the interaction techniques enabled a range of usage styles, from detailed review to high speed skimming. The study motivated the addition of phrase detection and topic suggestions to improve access to the audio recordings. Through these audio interaction techniques, the Audio Notebook defines a new approach for navigation in the audio domain.”

Singer, Andrew, Hindus, Debby, Stifelman, Lisa and White, Sean (1999): Tangible Progress: Less is More in Somewire Audio Spaces. In: Altom, Mark W. and Williams, Marian G. (eds.) Proceedings of the ACM CHI 99 Human Factors in Computing Systems Conference May 15-20, 1999, Pittsburgh, Pennsylvania. pp. 104-111. Available online

“We developed four widely different interfaces for users of Somewire, a prototype audio-only media space. We informally studied users' experiences with the two screen-based interfaces. We prototyped a non-screen-based interface as an example of a novel tangible interface for a communication system. We explored the conflict between privacy and simplicity of representation, and identified two unresolved topics: the role of audio quality and the prospects for scaling audio spaces beyond a single workgroup. Finally, we formulated a set of design guidelines for control and representation in audio spaces, as follows: GUIs are not well-suited to audio spaces, users do not require control over localization or other audio attributes, and awareness of other users' presence is desirable.”

Hindus, Debby, Arons, Barry, Stifelman, Lisa, Gaver, Bill, Mynatt, Elizabeth D. and Back, Maribeth (1995): Designing Auditory Interactions for PDAs. In: Robertson, George G. (ed.) Proceedings of the 8th annual ACM symposium on User interface and software technology November 15 - 17, 1995, Pittsburgh, Pennsylvania, United States. pp. 143-146. Available online

“This panel addresses issues in designing audio-based user interactions for small, personal computing devices, or PDAs. One issue is the nature of interacting with an auditory PDA and the interplay of affordances and form factors. Another issue is how both new and traditional metaphors and interaction concepts might be applied to auditory PDAs. The utility and design of nonspeech cues are discussed, as are the aesthetic issues of persona and narrative in designing sounds. Also discussed are commercially available sound and speech components and related hardware tradeoffs. Finally, the social implications of auditory interactions are explored, including privacy, fashion and novel social interactions.”

Stifelman, Lisa (1995): A Tool to Support Speech and Non-Speech Audio Feedback Generation in Audio Interfaces. In: Robertson, George G. (ed.) Proceedings of the 8th annual ACM symposium on User interface and software technology November 15 - 17, 1995, Pittsburgh, Pennsylvania, United States. pp. 171-179. Available online

“Development of new auditory interfaces requires the integration of text-to-speech synthesis, digitized audio, and non-speech audio output. This paper describes a tool for specifying speech and non-speech audio feedback and its use in the development of a speech interface, Conversational VoiceNotes. Auditory feedback is specified as a context-free grammar, where the basic elements in the grammar can be either words or non-speech sounds. The feedback specification method described here provides the ability to vary the feedback based on the current state of the system, and is flexible enough to allow different feedback for different input modalities (e.g., speech, mouse, buttons). The declarative specification is easily modifiable, supporting an iterative design process.”

Stifelman, Lisa, Arons, Barry, Schmandt, Chris and Hulteen, Eric A. (1993): VoiceNotes: A Speech Interface for a Hand-Held Voice Notetaker. In: Ashlund, Stacey, Mullet, Kevin, Henderson, Austin, Hollnagel, Erik and White, Ted (eds.) Proceedings of the ACM CHI 93 Human Factors in Computing Systems Conference April 24-29, 1993, Amsterdam, The Netherlands. pp. 179-186. Available online

“VoiceNotes is an application for a voice-controlled hand-held computer that allows the creation, management, and retrieval of user-authored voice notes -- small segments of digitized speech containing thoughts, ideas, reminders, or things to do. Iterative design and user testing helped to refine the initial user interface design. VoiceNotes explores the problem of capturing and retrieving spontaneous ideas, the use of speech as data, and the use of speech input and output in the user interface for a hand-held computer without a visual display. In addition, VoiceNotes serves as a step toward new uses of voice technology and interfaces for future portable devices.”
