Abstract (en)
[origin: WO0237477A1] A speech coder (100, 200) for a speech communications unit includes a set of at least two embedded vector codebooks capable of representing an input speech signal by a series of vectors. The at least two embedded vector codebooks (256, 262) share at least some common vectors of the series of vectors. The speech coder includes means for classifying (252) an input speech signal by selecting one of the at least two embedded vector codebooks in conjunction with at least a portion of at least one other embedded vector codebook of the at least two embedded vector codebooks (256, 262) to represent the input speech signal.
