Les systèmes de reconnaissance vocale se composent d'un module de reconnaissance et d'un module de détéection de parole. Le module de détection indique les périodes de paroleau module de reconnaissance; les non détection de parole sont donc des erreurs graves, ainsi que les détection de bruit qui peuvent être reconnues comme des mots du vocabulaire. Dans le cadre de la parole continue une plus grande précision des frontières des phrases détectées est de plus exigéee afin d'éviter les insertions ou omissions de mots qui peuvent perturber la reconnaissance de toute la phrase de part l'application d'un modèle de langage. Dans kla première partie nous proposons une méthode d'évaluation rigoureuse pour examiner en détail les influences d'un module de détection sur un système de reconnaissance. l'évaluation est effectuée à la fois au niveau des résultats de détection et du système de reconnaissance. Nous montrons que les performances du module de détection sont insuffisantes d'une part pour des communications bruitées, et d'autre part dans le cas de la détection de parole continue. ...

CETTE THESE EST CONSACREE D'UNE PART A L'ETUDE ET LA REALISATION DE SYSTEMES DE RECONNAISSANCE DE LA PAROLE INDEPENDANTS DU LOCUTEUR, D'AUTRE PART A UNE ETUDE DES METHODES PERMETTANT A CE TYPE DE SYSTEME DE CONSERVER DE BONNES PERFORMANCES LORSQU'ILS SONT UTILISES EN MILIEU BRUYANT. DANS UNE PREMIERE PARTIE, NOUS PRESENTONS LES PRINCIPES THEORIQUES LIES A LA MODELISATION DU VOCABULAIRE PAR L'UTILISATION DES CHAINES DE MARKOV CACHEES (HMM), SUIVIE D'UN EXPOSE PORTANT SUR LA REALISATION DE DEUX SYSTEMES DE RECONNAISSANCE APPELES SR01 ET SR02. LA MISE EN UVRE DU SR01 SUR UN SYNTHETISEUR DE PAROLE, LE TSP50C10, NOUS PERMET DE PRESENTER UNE APPROCHE FAIBLE COUT DU DIALOGUE HOMME-MACHINE. LE SR02 EST, UNE VERITABLE STATION DE TRAITEMENT DE SIGNAL PERMETTANT LE TRAITEMENT ET LA RECONNAISSANCE DE SIGNAUX DE PAROLE EN TEMPS REEL OU PRE-ENREGISTRES. NOUS METTONS ENSUITE EN EVIDENCE LA CHUTE DU TAUX DE BONNES RECONNAISSANCES OBTENUES LORSQUE LE SR02 TRAVAILLE EN MILIEU BRUYANT. NOUS ETUDIONS ET METTONS EN UVRE TROIS ALGORITHMES REALISANT LA PRISE EN COMPTE DU BRUIT AMBIANT DIRECTEMENT DANS LES MODELES HMM DU VOCABULAIRE. DANS UNE SECONDE PARTIE, NOUS COMMENCONS PAR UNE ETUDE ELEMENTAIRE DU BRUIT SEVISSANT DANS L'HABITACLE D'UNE VOITURE, CETTE ANALYSE ETANT SOUS-JACENTE A L'APPLICATION DU SR02 A LA COMMANDE VOCALE D'UN TELEPHONE MAINS LIBRES. NOUS EXPOSONS ENSUITE DES METHODES DE PRE-TRAITEMENT MIS EN UVRE EN VUE D'UNE AUGMENTATION DU RAPPORT SIGNAL SUR BRUIT (SNR) DU SIGNAL A RECONNAITRE AVANT SON UTILISATION PAR L'ALGORITHME DE RECONNAISSANCE DU SR02

The Cognition Of Basic Musical Structures written by David Temperley and has been published by MIT Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2004-08-20 with Music categories.
In this book, David Temperley addresses a fundamental question about music cognition: how do we extract basic kinds of musical information, such as meter, phrase structure, counterpoint, pitch spelling, harmony, and key from music as we hear it? Taking a computational approach, Temperley develops models for generating these aspects of musical structure. The models he proposes are based on preference rules, which are criteria for evaluating a possible structural analysis of a piece of music. A preference rule system evaluates many possible interpretations and chooses the one that best satisfies the rules. After an introductory chapter, Temperley presents preference rule systems for generating six basic kinds of musical structure: meter, phrase structure, contrapuntal structure, harmony, and key, as well as pitch spelling (the labeling of pitch events with spellings such as A flat or G sharp). He suggests that preference rule systems not only show how musical structures are inferred, but also shed light on other aspects of music. He substantiates this claim with discussions of musical ambiguity, retrospective revision, expectation, and music outside the Western canon (rock and traditional African music). He proposes a framework for the description of musical styles based on preference rule systems and explores the relevance of preference rule systems to higher-level aspects of music, such as musical schemata, narrative and drama, and musical tension.
