CA 2409308

A method and system for synthesizing audio speech is provided. A synthesis engine receives from a host, compressed and normalized speech units and prosodic information. The synthesis engine decompresses data and synthesizes audio signals. The synthesis engine can be implemented on a digital signal processing system which can meet requirements of low resources (i.e. low power consumption, lower memory usage), such as a DSP system including an input/output module, a WOLA filterbank and a DSP core that operate in parallel.

Méthode et système de synthèse vocale audio. Un appareil de synthèse reçoit, à partir d'un hôte, des unités de paroles compressées et normalisées et des informations prosodiques. Ledit appareil de synthèse décompresse les données et synthétise les signaux audio. L'appareil de synthèse peut être implanté dans un système de traitement de signaux numériques qui peut remplir des exigences de faibles ressources (c.-à-d., une faible consommation de puissance, une faible utilisation de la mémoire), telles qu'un système DSP comprenant un module entrée/sortie, un banc de filtres WOLA et une mémoire centrale DSP qui fonctionnent en parallèle.
