This paper describes the approach followed in the development of the linguistic proces- sor of the continuous speech dialog system im- plemented at our labs. The application sce- nario (voice-based information retrieval ser- vice over the telephone) poses severe specifi- cations to the system: it has to be speaker- independent, to deal with noisy and corrupted speech, and to work in real time. To cope with these types of applications requires to improve both efficiency and accuracy. At present, the system accepts telephone-quality speech (utterances referring to an electronic mailbox access, recorded through a PABX) and, in the speaker-independent configuration, it correctly understands 72% of the utterances in about twice real time. Experimental results are discussed, as obtained from an ...
