Abstract

L'invention concerne un procédé et un dispositif destinés à invoquer un fichier de synthèse de parole. Ledit procédé consiste : à détecter si un client possède un fichier de synthèse de parole devant être utilisé par une application enregistrée (S101), l'application enregistrée étant une application préenregistrée requérant l'utilisation d'un fichier de synthèse de parole ; s'il est détecté que le client ne possède pas de fichier de synthèse de parole, à télécharger, selon un fichier de configuration de parole pré-stocké correspondant à l'application enregistrée, un fichier de synthèse de parole à partir d'un côté serveur correspondant à l'application enregistrée (S103), le fichier de configuration de parole comprenant l'adresse de téléchargement du fichier de synthèse de parole ; et s'il est détecté que le client possède le fichier de synthèse de parole, à invoquer le fichier de synthèse de parole du client (S102), de sorte que l'application enregistrée effectue une lecture de parole selon le fichier de synthèse de parole. Lorsqu'une application enregistrée doit utiliser un fichier de synthèse de parole, s'il est détecté qu'un client possède un fichier de synthèse de parole, et si le client possède un fichier de synthèse de parole, le fichier de synthèse de parole mis en cache dans le client est de préférence invoqué, réduisant le temps de réponse de l'ensemble du système de parole.
