摘要

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.
