Abstract
PURPOSE: To prevent the generation of misrecognition by detecting the start end of a consonant part of a voice in relation to calculated energy >= about 700Hz. CONSTITUTION: An amplifier 12 amplifies the level of a voice collected by a microphone 11 to a level matched with succeeding processing. A RAM 17 is used for working an intermediate/high frequency energy change rate buffer 17e in which the short time energy change rate of a frequency component >=700Hz is written. Then a CPU 15 detects a retrieving section, i.e., a vowel section, for detecting a frame to be the start end of a consonant and detects the start end of the consonant by setting up a frame other than the vowel section as a consonant detection section. Consequently error-reduced detection is accomplished without being affected by a buzz sound or the like, and in the case of executing voice recognition by using the start end of the detected consonant, misrecognition is suppressed.
