Voice response systems

La premiere partie de cet article donne un apercu des techniques communes pour representer la parole dans les systemes a reponse vocale. Presentation de deux principales classes de techniques ― le codage a forme d'ondes et le codage parametrique ― et leurs variantes. On discute le codage, le decodage et les techniques de synthese aussi bien que les avantages et desavantages de chaque methode. La seconde partie donne un apercu de deux types de systemes a reponse vocale
