Speech operated automatic inquiry system
First Claim
1. A process for voice recognition comprising a step of acquiring an acoustic signal, a step of acoustic-phonetic decoding and a step of linguistic decoding, characterized in that the linguistic decoding step comprises the steps:
- of disjoint application of a plurality of language models to the analysis of an audio sequence for the determination of a plurality of sequences of candidate words;
of determination by a search engine of the most probable sequence of words from among the candidate sequences.

Abstract
The subject of the invention is a process for voice recognition comprising a step of acquiring an acoustic signal, a step of acoustic-phonetic decoding and a step of linguistic decoding.
According to the invention, the linguistic decoding comprises the steps:
of disjoint application of a plurality of language models to the analysis of an audio sequence for the determination of a plurality of sequences of candidate words;
of determination by a search engine of the most probable sequence of words from among the candidate sequences.
The subject of the invention is moreover a device for implementing the process.

5. A device for voice recognition comprising an audio processor (2) for the acquisition of an audio signal and a linguistic decoder (6) for determining a sequence of words corresponding to the audio signal
characterized in that the linguistic decoder comprises a plurality of language models (8) for disjoint application to the analysis of one and the same sentence for the determination of a plurality of candidate sequences, a search engine for the determination of a most probable sequence from among the plurality of candidate sequences.
