Distributed speech recognition system
First Claim
1. A distributed speech recognition system comprising at least one user terminal and at least one server suitable for communication with one another via a telecommunications network, wherein the user terminal comprises:
- means for obtaining an audio signal to be recognized;
first audio signal modeling parameter calculation means; and
first control means for selecting at least one signal to be transmitted to the server, from the audio signal to be recognized and a signal indicating the calculated modeling parameters. and wherein the server comprises;
means for receiving the selected signal originating from the user terminal;
second input signal modeling parameter parameter calculation means;
recognition means for associating at least one stored form with input parameters; and
second control means for controlling the second calculation means and the recognition means in order, if the selected signal received by the reception means is an audio signal, to activate the second parameter calculation means by addressing the selected signal to them as an input signal, and to address the parameters calculated by the second calculation means to the recognition means as input parameters, and if the selected signal received by the reception means indicates modeling parameters, to address said indicated parameters to the recognition means as input parameters.
