A trained vector creating part 15 creates a characteristic of an unvoiced sound in advance as a trained vector V. Meanwhile, a threshold value THD for distinguishing a voice from a background sound is created based on a predictive residual power e of a sound which is created during a non-voice period.

Children's Recognition of Cartoon Voices
Journal of Speech, Language, and Hearing Research, 2002We examined developmental changes in talker recognition skills by assessing 3-, 4-, and 5-year-old children's recognition of 20 cartoon characters' voices. For each participant, the character set was subdivided into more and less familiar talkers based on the participant's ability to name each character. Four- and 5-year-old children recognized more of

Disclosed is a voice recognition apparatus which can prevent an erroneous manipulation due to erroneous voice recognition from being carried out even in a noisy environment. As long as a duration of utterance acquired based on the level of a voice signal uttered by an operator (user) approximately coincides with a duration of utterance acquired based ...

A speech recognition circuit in which acoustic power spectrum data corresponding to an input speech signal are sequentially generated, a vowel segment is determined based on the acoustic power spectrum data, and a vowel and a consonant are recognized based on the respective acoustic power spectrum data in the vowel segment and outside the vowel segment.

Human recognition of familiar voices
The Journal of the Acoustical Society of America, 2015Recognizing familiar voices is something we do every day. In quiet environments, it is usually easy to recognize a familiar voice. In noisier environments, this can become a difficult task. This paper examines how robust listeners are at identifying familiar voices in noisy, changing environments and what factors may affect their recognition rates ...
