SRG - Speech Recognition Group

Il gruppo Speech Recognition copre la maggior parte degli aspetti del riconoscimento vocale, dello speaker e del linguaggio, l'elaborazione dei segnali acustici, la fonetica e la modellazione lessicale.

Principali contributi scientifici: sistemi di riconoscimento automatico di large vocabulary,  riconoscimento vocale automatico, riconoscimento di speaker e linguaggio robusto rispetto alle variazioni del canale.

La maggior parte delle applicazioni rilevanti negli ultimi anni hanno riguardato:

• Collaborazione allo sviluppo del riconoscitore vocale Loquendo ASR
• Collaborazione allo sviluppo di un sistemi automatici Directory Assistance di Telecom Italia
• Collaborazione allo sviluppo del sistema di riconoscimento del parlatore Nuance
