Distributed speech recognition method
First Claim
1. A distributed speech recognition method, comprising at least one user terminal and at least one server, capable of communicating with one another via a telecommunications network, wherein, at the user terminal, at least the following steps are performed:
- obtain an audio signal to be recognized;
calculate modeling parameters for the audio signal to be recognized;
attempt to associate a stored form with the modeling parameters; and
independently of the step for attempting to associate a stored form, select a signal from at least the audio signal to be recognized and a signal indicating the modeling parameters, as a function of criteria relating to loading issues of the various processing means at the level of the terminal and of the server, and/or as a function of criteria relating to the availability of voice or data transmission channels;
sending the selected signal to the server; and
wherein, at the server, at least the following steps are performed;
receive the signal transmitted by the user terminal; and
attempt to associate a stored form with the received signal.

Abstract
This invention relates to a distributed speech recognition method comprising at least one user terminal and at least one server which can communicate with each other by means of a telecommunication network. The inventive method comprises the following steps consisting in: at the user terminal, attempting to associate a saved form with the signal to be recognized and, independently of said step, transmitting a signal to the server, indicating the signal to be recognized; and, at the server, attempting to associate a saved form with the signal received.

9. A user terminal adapted for cooperating with a server, comprising:
-
means for obtaining an audio signal to be recognized; means for calculating modeling parameters for the audio signal; and recognition means for associating at least one stored form with modeling parameters calculated by the calculation means; and control means for selecting a signal to be transmitted to the server from between the audio signal to be recognized and a signal indicating the modeling parameters calculated, the selecting based on a function of criteria relating to loading issues of the various processing means at the level of the terminal and of the server, and/or on a function of criteria relating to the availability of voice or data transmission channels. - View Dependent Claims (10, 11, 12, 13)
