Very Low Rate Speech Coding Algorithm Based on Biomimetic Pattern Recognition ⋆

چکیده
Based on the speech coding technology, in this paper we propose a new method encoding the speech signal by the bionic pattern recognition technique. Using this new encoding method, the text message can be received after using biomimetic pattern recognition of the speaker’s voice. And the information related to the speaker’s individual characteristics can be obtained by “comparison” between the speaker’s voice and the standard voice which corresponding to the text message. Then the text message and individual characteristics information are encoded before transmission. Compared with the application of traditional speech recognition in low-rate speech coding, the scheme using biomimetic pattern recognition is single template identification with a faster recognition speed and lower instructions (keywords) false acceptance rate, which nearly reaches the limits of the voice coding rate. This new method is anticipated to have great potential application in military communications, underwater communications, secure communications and other demands under special conditions.

Classification of emotional speech using spectral pattern features
Speech Emotion Recognition (SER) is a new and challenging research area with a wide range of applications in man-machine interactions. The aim of a SER system is to recognize human emotion by analyzing the acoustics of speech sound. In this study, we propose Spectral Pattern features (SPs) and Harmonic Energy features (HEs) for emotion recognition. These features extracted from the spectrogram ...

متن کاملA Pattern Recognition Approach to Voiced — Unvoiced — Silence Classification with Applications to Speech Recognition
Absb-act—In speech analysis, the voiced-unvoiced decision is usually performed in conjunction with pitch analysis. The linking of voiced-unvoiced (V-UV) decision to pitch analysis not only results in unnecessary complexity, but makes it difficult to classify short speech segments which are less than a few pitch periods in duration. In this paper, we describe a pattern recognition approach for d...
