Abstract
A voice sample characterization front-end suitable for use in a distributed speech recognition context. A digitized voice sample (31) is split between a low frequency path (32) and a high frequency path (33). Both paths are used to determine spectral content suitable for use when determining speech recognition parameters (such as cepstral coefficients) that characterize the speech sample for recognition purposes. The low frequency path (32) has a thorough noise reduction capability. In one embodiment the results of this noise reduction are used by the high frequency path (33) to aid in de-noising without requiring the same level of resource capacity as used by the low frequency path (32).
