The speech processing system which applies the processing method, and this method of the aural signal

摘要

In the method of processing the aural signal, the left (L) and the right (R) (L+R) the synthetic speech signal and the synthetic speech signal (L-R) you obtain from the aural signal. The synthesis which exceeds specified cycle numerical value (L-R) energy contents of the aural signal are measured, these energy contents are compared with specified threshold. After that, when energy contents are less than threshold, synthesis (L+R) it is obtained from the aural signal and at the same time synthesis (L-R) it adds the signal which correlation is cancelled, to the signal, the synthesis which is improved (L-R) it tries to acquire the aural signal, the left (L) and the right (R) the aural signal, synthesis (L+R) the signal and the synthesis which is improved (L-R) from the aural signal for the second time it acquires.
