Abstract

The invention relates to a voice recognition process comprising a step (601) of acoustic processing of voice samples (201) and a step (602) of determination of a command intended to be applied to at least one device, and in that said steps of acoustic processing and of determination of a command use a single representation (309) in memory (305) of a language model.

The invention also relates to corresponding devices (102) and computer program products.

Claims

1. A voice recognition process characterized in that it comprises a step (601) of acoustic processing of voice samples (201) and a step (602) of determination of a command intended to be applied to at least one device, and in that said steps of acoustic processing and of determination of a command use a single representation (309) in memory (305) of a language model.

2. The voice recognition process as claimed in claim 1, characterized in that said step of acoustic processing of voice samples comprises the identification of at least one set of semantic data (500 to 506) taking account of said voice samples and of said language model, said set directly feeding said command determination step.

3. The voice recognition process as claimed in any one of claims 1 and 2, characterized in that said step of determination of a command comprises a substep of generation of a set of semantic data on the basis of said language model and of the result of said acoustic processing step, so as to allow the generation of said command.

4. The voice recognition process as claimed in claim 3, characterized in that said substep of generation of a set of semantic data comprises the supplying of said semantic data in tandem with a trellis backtrack.

7. A computer program product, characterized in that said program comprises sequences of instructions tailored to the implementation of a voice recognition process as claimed in any one of claims 1 to 4 when said program is executed on a computer.

5. A voice recognition device, characterized in that it comprises means of acoustic processing of voice samples and means of determination of a command intended to be applied to at least one device, and in that said means of acoustic processing and of determination of a command use one and the same representation (309) in memory (305) of a language model.

6. A computer program product comprising program elements, recorded on a medium readable by at least one microprocessor, characterized in that said program elements control said microprocessor or microprocessors so that they perform a step of acoustic processing of voice samples and a step of determination of a command intended to be applied to at least one device, said steps of acoustic processing and of determination of a command using one and the same representation in memory of a language model.
