VOICING ESTIMATION METHOD AND APPARATUS FOR SPEECH RECOGNITION BY LOCAL SPECTRAL INFORMATION

摘要

A method and apparatus of estimating a voicing for speech recognition by using local spectral information. The voicing estimation method for speech recognition includes performing a Fourier transform on input voice signals after performing pre-processing on the input voice signals. The method further includes detecting peaks in the input voice signals after smoothing the input voice signals. The method also includes computing every frequency bound associated with the detected peaks, and determining a class of a voicing according to each computed frequency bound.
