Effect of Speaking Rate on Chinese Speech Recognition for Foreign Students

Article Preview

Abstract:

Three room impulse responses with different reverberation time in mid-frequency were obtained at a listening position from a classroom model through room acoustical simulation. Chinese speech recognition for foreign students was performed under different speaking rate conditions using auralization method. Effect of reverberation time and speaking rate on Chinese speech recognition for foreign students was investigated. The results showed that reverberation time and speaking rate had a significant effect on Chinese recognition scores of foreign students. The shorter the reverberation time was and the slower the speaking rate was, the higher Chinese recognition scores of foreign students were. The longer the reverberation time was and the faster the speaking rate was, the lower Chinese recognition scores of foreign students were.
