METHOD AND APPARATUS FOR REAL TIME SPEECH RECOGNITION WITH AND WITHOUT SPEAKER DEPENDENCY |
摘要 |
A method and apparatus for real time speech recognition with and without speaker dependency which includes the following steps. Converting the speech signals into a series of primitive sound spectrum parameter frames; detecting the beginning and ending of speech according to the primitive sound spectrum parameter frame, to determine the sound spectrum parameter frame series; performing non-linear time domain normalization on the sound spectrum parameter frame series using sound stimuli, to obtain speech characteristic parameter frame series with predefined lengths on the time domain; performing amplitude quantization normalization on the speech characteristic parameter frames; comparing the speech characteristic parameter frame series with the reference samples, to determine the reference sample which most closely matches the speech characteristic parameter frame series; and determining the recognition result according to the most closely matched reference sample.
