Abstract
Quantization unit ( ) comprises evaluator ( ) and comparator ( ) in signal processing for identifying an utterance in system ( ). The evaluator ( ) weights a first intermediate result of an operation on a first set of a plurality of speech parameters ( ) differently than a second intermediate result of an operation on a second set of the plurality of speech parameters ( ) in a weighted representation of the plurality of speech parameters ( ). The comparator ( ) employs the weighted representation of the plurality of speech parameters ( ) to determine a vector index to represent the plurality of speech parameters ( ). The quantization unit ( ), in one example, can employ split vector quantization in conjunction with the weighted representation to determine a vector index to represent the plurality of speech parameters ( ).
