ABSTRACT:
Digital processing of speech signals for compression/expansion pitch change is provided by writing and reading a ROM at different rates and controlling the discard/repeat segments of memory to be approximately integral multiples of the pitch period with means to track the pitch period as it is changing and modify the discard/repeat segments accordingly.
