HCELP: Low Bit Rate Speech Coder for Voice Storage Applications

Existing standard speech coders can provide high quality speech communication. However, they tend to degrade the performance of automatic speech recognition (ASR) systems that use the reconstructed speech. The main cause of the degradation is in that ...

• We compared native English and non-native (Dutch) Lombard and plain speech.

Speech produced in noise (Lombard speech) is more intelligible than speech produced in quiet (plain speech). Previous research on the Lombard intelligibility benefit focused almost entirely on how native speakers produce and perceive ...

In this paper, we propose several entropy coding methods to further compress quantized mel-frequency cepstral coefficients (MFCCs) used for distributed speech recognition (DSR). As a standard DSR front-end, the European Telecommunications Standards ...
