The speaker veri:fication technique was evaluated with over 5000 words from 13 speakers employing telephone handsets and accessing a verification simulation over the switched telephone network. A total of 977 verifi.cation attempts and 21421 impersonation attempts was simulated. A false acceptance rate of 0.1% was attained after an average of 1.2 words input. The same conditions gave rise to a ...

The emergence of packet networks for both data and voice traffic has introduced new challenges for speech transmission designs that differ significantly from those encountered and handled in traditional circuit-switched telephone networks, such as the public switched telephone network (PSTN). In this chapter, we present the many aspects that affect speech quality in a voice over IP (VoIP) conve...

This paper addresses the problem of speaker-independent connected natural number recognition over telephone lines. Increasing the vocabulary from digits (0{9) to natural numbers (0{99) opens for more user-friendly services, but also introduces many new, language-speci c problems, such as more similar sounding words, a more complex grammar network, and more ambiguities due to segmentation proble...
