Speech processing is the study of speech signals and the processing methods of these signals. The signals are usually processed in a digital representation, so speech processing can be regarded as a special case of digital signal processing, applied to speech signal. Aspects of speech processing includes the acquisition, manipulation, storage, transfer and output of speech signals.

It is also closely tied to natural language processing (NLP), as its input can come from or output can go to NLP applications. E.g. text-to-speech synthesis may use a syntactic parser on its input text and speech recognition's output may be used by e.g. information extraction techniques. The main applications of speech processing are the recognition, synthesis and compression and manipulation of human speech.

Speech processing includes the following areas of study:
