1. A method for voice recognition, the method comprising: obtaining a voice signal for an utterance of a speaker; determining a runtime pitch from the voice signal for the utterance; categorizing the speaker as male, female or child based on the runtime pitch; using the categorization as a basis for dynamically adjusting a maximum frequency f max and a minimum frequency f min of a filter bank used for processing the input utterance to produce an output, and using corresponding gender or age specific acoustic models to perform voice recognition based on the filter bank output.
