CSTR is a multidisciplinary research group that undertakes application-oriented speech research. Its main work is in the areas of speech synthesis and speech recognition. Its goals are both to do original research which can be published in the open literature, and to see the results of its work embodied in technologies that are of benefit to users. It is interested in collaborating with outside academic or industrial partners in pursuit of either or both of these goals.
COCOSDA (The International Committee for the Co-ordination and Standardisation of Speech Databases and Assesment Techniques for Speech Input/Output) (Advanced Telecommunications Research Institute)
"The International Committee for the Co-ordination and Standardisation of Speech Databases and Assesment Techniques for Speech Input/Output, COCOSDA, has been established to encourage and promote international interaction and cooperation in the foundation areas of Spoken Language Processing. The importance of collaboration which transcends national boundaries is increasingly recognized. This is both because of the practical and scientific value attached to systematic work which encompasses a range of languages and analytic approaches and also because of the practical need to establish common methods of performance description and quantitative comparison. "
This site provides a range of information on speech technology, including speech synthesis, speech recognition, speech coding, and related material. The information is regularly posted to the comp.speech newsgroup as the "comp.speech FAQ" posting.
Automatic speech recognition is the process by which a computer maps an acoustic speech signal to text. Automatic speech understanding is the process by which a computer maps an acoustic speech signal to some form of abstract meaning of the speech. Speech synthesis is the task of transforming written input to spoken output. The input can either be provided in a graphemic/orthographic or a phonemic script, depending on its source. As a consequence of its reliance on phonology, linguistics, signal processing, statistics, computer science, acoustics, connectionist networks, psychology and other fields, there are many technologies involved in speech technology.
"Research at IPO aims to increase the usability of technological innovations, by directing its research at the improvement of the User Interface, i.e., by tuning existing interaction techniques to the capacities and limitations of the users, and by exploring new ways of interaction. In this way new technology should be better adjusted to the wants, needs and capacities of the users. One possibility for interaction is speech."
Imagine talking to a computer to find a needle-in-the haystack job listing, or showtimes of a movie premiere at the closest theater. Today, obtaining such information online requires a programmed transaction between the user, who clicks through a pre-determined sequence of options and views results, and the computer, which retrieves user-selected data. With spoken language systems, however, user and machine can engage in a spontaneous, interactive conversation, incrementally arriving at the desired information in far fewer steps.
