Une approche pour l'amélioration des signaux vocaux corrompus par un bruit coloré additif est proposée et l'architecture du système pour mettre en œuvre l'idée proposée dans la communication en temps réel est présentée dans cet article. Une combinaison d'une technique de filtrage FIR passe-bande avec un filtrage Wiener est utilisée pour améliorer la SNR pour les signaux vocaux. La moyenne SNR amélioration (entre entrée et sortie SNR) est de 22.48 dB. Les bruits additifs sont le son d'un avion à turbopropulseur. Le système, qui présente d'excellentes performances, est conçu sur la base d'un DSP à virgule fixe 16 bits (ADSP-2181) d'Analog Devices. Les résultats expérimentaux démontrent que le filtre FIR conduit à un gain significatif en SNR, donc une amélioration visible de la qualité et de l'intelligibilité de la parole.

Abstract: An approach to the enhancement of speech signals corrupted by additive colored noise is proposed and the system architecture to implement the proposed idea in real-time communication is introduced in this paper. A combination of a bandpass FIR filtering technique with wiener filtering is used to improve the SNR for speech signals. The average SNR improvement (between input and output SNR) is 22.48 dB. The additive noises are the sound from a turbo prop aircraft. The system, which shows excellent performance, is designed based on a 16 bits fixed point DSP (ADSP-2181) from Analog Devices. Experiment results demonstrate that the FIR filter leads to a significant gain in SNR, thus visibly improvement for the quality and the intelligibility of the speech.
