The Voice Energy Estimate and Endpoint Detection Algorithm Based on Speech Observation Sequence in Compressing Sensing

Based on the theory of compressing sensing,this paper analyzes the theory of voice energy estimate based on the observation sequence of compressing sensing.The accuracy of energy estimate is evaluated with different compression rate.Then the result of voice energy estimate is used as the basis of speech endpoint detection with pink noise,Gaussian noise and car noise.This paper also makes the comparison with the cepstral distance based on speech observation sequence and the energy endpoint detection based on traditional Nyquist sampling,reducing the amount of computation.
