Abstract:Automatic Speech Recognition (ASR) is called to play a relevant role in the provision of spoken interfaces for IP-based applications. However, as a consequence of the transit of the speech signal over these particular networks, ASR systems need to face two new challenges: the impoverishment of the speech quality due to the compression needed to fit the channel capacity and the inevitable occurrence of packet losses.In this framework, bitstream-based approaches that obtain the ASR feature vectors directly from … Show more
“…In [27][28][29], a voice over IP (VoIP) channel is simulated using such a model. References [30,31] simulate IP channels and use a 2-state Gilbert model to simulate burst type packet loss on the channel.…”
