CA 2745991

Methods and systems for adapting of acoustic models are disclosed. A user terminal may determine a phoneme distribution of a text corpus, determine an acoustic model gain distribution of phonemes of an acoustic model before and after adaptation of the acoustic model, determine a desired phoneme distribution based on the phoneme distribution and the acoustic model gain distribution, generate an adaption sentence based on the desired phoneme distribution, and generate a prompt requesting a user speak the adaptation sentence.

Linvention concerne des procédés et des systèmes dadaptation de modèles acoustiques. Un terminal dutilisateur peut déterminer une distribution de phonèmes dun corps de texte, déterminer une distribution du gain de modèle acoustique des phonèmes dun modèle acoustique avant et après ladaptation du modèle acoustique, déterminer une distribution souhaitée des phonèmes en se basant sur la distribution des phonèmes et la distribution du gain de modèle acoustique, générer une phrase dadaptation en se basant sur la distribution souhaitée des phonèmes et générer une invitation demandant à un utilisateur de prononcer la phrase dadaptation.
