Speech signal processing refers to the acquisition, manipulation, storage, transfer and output of vocal utterances by a computer. The main applications are the recognition, synthesis and compression of human speech:
- Speech recognition (also called voice recognition) focuses on capturing the human voice as a digital sound wave and converting it into a computer-readable format.
- Speech synthesis is the reverse process of speech recognition. Advances in this area improve the computer's usability for the visually impaired.
- Speech compression is important in the telecommunications area for increasing the amount of information which can be transferred, stored, or heard, for a given set of time and space constraints.
- Speaker diarization is the process of determining who spoke when in a signal.
