ABSTRACT:
This invention relates to a speech recognition apparatus for raising the recognition speed, which is provided with first and second processors, the first processor mainly carrying out feature extraction of the input speech, the second one mainly carrying out comparison and distinction of feature extraction patterns with and from the reference patterns, thereby processing the feature extraction hand comparison and distinction in an equilibrium manner and expecting the speech recognition at high speed. Another apparatus has been proposed which allows the first processor to carry out the comparison and distinction process in parts, thereby raising the recognition rate and performing the recognition at further high speed.
