Abstract: The use of Bai language is impacted by foreign economics and cultures, which has put it in an increasingly dangerous situation of extinction. To solve this problem, this paper proposes to build a corpus for Bai speech recognition and speech synthesis application. Solutions are provided for the problems in data collection and processing, system structure and data storage structure of the corpus, and also the interface between linguistic research and the corpus.

Key words: Bai language, corpus, speech corpus, speech recognition
