1. An acoustic front-end device comprising: a frame parser receiving an acoustic signal and parsing the received acoustic signal into a plurality of frames; a plurality of correlators, each of the correlators correlating each of the plurality of frames with one or more acoustic property sets to produce a first set of acoustic property correlations; a controller retrieving one or more speech characteristic samples from one or more speech codebooks based on the first set of acoustic property correlations; and a speech characteristic probability generator configured to: generate a plurality of speech characteristic probabilities over one or more subsequent frames of the plurality of frames by individually correlating a digital signal component of the subsequent frame with the one or more acoustic property sets to produce a second set of acoustic property correlations; and a processor configured to interpret the plurality of speech characteristic probabilities to generate at least a language probability and a language syntax bias; and select a plurality of words from a series of plurality of words based on the language probability and the language syntax bias; and output the plurality of words through an interface.
3. The device of claim 1 , wherein the one or more speech codebooks store a plurality of the speech characteristic samples comprising a plurality of speech characteristics.
