Combined effect of noise and vibration on articulation of Chinese syllable
Abstract:
To study combined effect of noise and vibration on articulation, changes of the speech features of Chinese single syllabic utterances were investigated under combined factors. The experiments were conducted under four conditions: combined noise and vibration, simple noise, simple vibration and control. A set of signal processing system was established, programs for speech signal analysis and statistics were developed. The results showed that, as compared with simple noise , simple vibration or control condition, the fundamental frequency, energy and duration of articulation under combined conditions increased significantly. It suggests that the effect of noise and vibration should be considered in the design of aerospace speech recognition system.
