SYSTEM FOR IMPROVING SPEECH INTELLIGIBILITY THROUGH HIGH FREQUENCY COMPRESSION |
摘要 |
A speech enhancement system that improves the intelligibility and the perceived quality of processed speech includes a frequency transformer and a spectral compressor. The frequency transformer converts speech signals from the time domain to the frequency domain. The spectral compressor compresses a pre-selected portion of the high frequency band and maps the compressed high frequency band to a lower band limited frequency range. |
