Abstract

PURPOSE: To prevent noise from being misdetected as a voice by detecting the voice by using a standard vowel pattern and detecting an inputted sound as a voice only when the sound is a user's voice. CONSTITUTION: This system is provided with a standard vowel pattern memory 1 which is stored with standard vowel patterns of a user given previously from outside, a matching part 2 which matches an externally inputted pattern against the standard vowel patterns and calculates the similarity between the both, and a voice detection part 3 which performs voice detection by using the similarity. Consequently, noise, etc., is never detected as a voice and the voice detection can be performed with high performance even in very noisy environment as compared with a voice detection system which uses power.
