Abstract： Digital speech processing is a digital method for transmitting， storing， recognizing and encoding speech， which involves many disciplines and is widely used in digital communication， language learning， automatic translation， artificial intelligence and many other fields. Filters play an important role in digital signal processing. A low-pass filter is designed to filter the speech signal to obtain the low frequency component of the speech signal.

Key words： speech signal; speech process; digital signal; low-pass filter; spectrum
