Design and realization of smart speech processors

In this paper we propose new realizations of small and mobile audio processors applied to speech signal analysis. Proposed algorithms give us a possibility to compare feature vectors of the current speaker voice with the base containing stored vectors of known speakers. Application of microprocessors and integrated circuits dedicated to analysis of audio frequency signals, demands very often modification of several algorithms. Proposed algorithms permit for on-line realization of speaker identification and emotion recognition. The possibility of integrated CMOS realization for different components of audio processing has been also discussed.
