In a system or method of voice or speech recognition, a voice waveform signal modeled as the product of a power component and an informational component is divided into higher and lower frequency signals, corresponding to the information signal and the power signal. The signals are amplified separately and then combined. By applying higher amplification to the information signal, a more detailed sample of the initial waveform can be provided to voice recognition or word recognition apparatus. |
