Acoustic Parameter Databases of Dagur, Evenki, Oroqen nationalities

Building Unified Acoustic Parameter Databases of Minority Languages in China is a pioneering work, which could promote standardization and computerization of minority phonetics, provide scientific evidences for speech education, speech recognition & speech synthesis, protect weak and endangered languages with modern and scientific means, ensure resources sharing and continuance of phonetic research. After establishing databases of Tibetan, Uigur and Yi languages, we expanded the databases with three endangered minority languages of Dagur, Evenki, and Oroqen. In the process of building Acoustic Parameter Databases we improved rules and approaches of measuring acoustic parameter and made some research of endangered languages such as their prosodic pattern features and frequently-used flap phoneme.
