Making Full Use of Speech Corpora 

Professor Thomas Fang Zheng, Tsinghua University 

Abstract: It is well understood that the speech databases play a very important role for speech recognition. It is a dream for speech recognition researchers to create a more useful database with a smaller effort. To achieve this goal, the database should be well designed at first, and tools and more information should be provided so that it can be made full use of. This paper will illustrate the criteria according to which the database will be created for different purposes. The way of transcription will also be discussed, which is the first thing to do after the data creation. Then an example on how to learn knowledge from the created database for other research purpose will be given.
