Title (EN) METHODS AND APPARATUS FOR ASR WITH EMBEDDED NOISE REDUCTION
(FR) PROCÉDÉS ET APPAREIL POUR ASR AVEC RÉDUCTION DE BRUIT INTÉGRÉE
Abstract:
(EN) Methods and apparatus for performing feature extraction on speech in a microphone signal with embedded noise processing to reduce the amount of processing. In embodiments, feature extraction and the noise estimate use an output of the same Fourier Transform, such that the noise filtering of the speech is embedded with the feature extraction of the speech.
(FR) L'invention concerne des procédés et un appareil pour effectuer une extraction de caractéristiques sur la parole dans un signal de microphone à traitement du bruit intégré afin de réduire le volume de traitement. Dans des modes de réalisation, l'extraction de caractéristiques et l'estimation du bruit utilisent un résultat de la même transformée de Fourier, de telle sorte que le filtrage de bruit de la parole soit intégré à l'extraction de caractéristiques de la parole.
