ABSTRACT:
A speech signal fundamental period extractor which receives a residual value signal from a speech analyzer, such as one using autocorrelators. The residual value signal is first passed through a filter to remove the high-frequency components. Then the signal is quantized to obtain low-bit quantization of the residual value. The output from the quantizer is then sent to an autocorrelator to obtain the correlation coefficient and the fundamental period is extracted by selecting the position of a maximum correlation coefficient. This provides more accurate results and permits the use of low-speed elements and a reduction of components.
