Methods and apparatus are provided which may be employed to perform speech recognition processing on a grid computing system. In some embodiments, the grid computing system includes a server system which receives processing tasks from one or more client applications, divides the processing tasks into units of work, and assigns the units of work to one or more of the nodes. Dividing a processing task into units of work may involve dividing audio input data into segments defined by natural speech boundaries. A mathematical representation may be created for each segment prior to its distribution on the grid to minimize network traffic. A node in the system may perform heterogeneous units of work concurrently, such as by isolating the execution of each unit of work in an application domain.

L'invention concerne des procédés et un appareil de traitement de reconnaissance vocale dans un système de calcul distribué. Dans certains modes de réalisation, le système de calcul distribué comporte un système serveur qui reçoit des tâches de traitement d'une ou de plusieurs applications clients, divise les tâches de traitement en unités de travail et affectent les unités de travail à un ou plusieurs noeuds. La division d'une tâche de traitement en unités de travail peut comprendre la division de données d'entrée audio en segments définis par une limite vocale naturelle. Une représentation mathématique peut être créée pour chaque segment avant sa distribution sur la grille afin de minimiser le trafic du réseau. Un noeud du système peut exécuter des unités hétérogènes de travail simultanément, par exemple par l'isolation de l'exécution de chaque unité de travail dans un domaine d'application.
