A Framework of Speech Transcription by a Large Number of Participants
Using a Speech Decomposition Front-end
Takashi SAITO
Abstract:
A wide variety of digital contents with speech data are appearing on the internet such as podcasts and videos. Text information transcribed from these contents is not only essential to people with hearing impaired, but also expected to add new service values to the technologies of information retrieval and data mining. On the other hand, the work of transcribing speech is intrinsically labor-intensive and its automation by using speech recognition still has a limitation in the variety of contents. In this paper, a framework of speech transcription comprised of speech processing by computer and human labor aggregated from a large number of participants is presented. The feasibility of the framework is demonstrated through experiments for the core part, speech decomposition front-end, by using various types of digital contents.
