Speech signal processing refers to the acquisition, manipulation, storage, transfer and output of human utterances by a computer. The main goals are recognition, synthesis and speech compression.
- Speech recognition (also called voice recognition) focuses on capturing utterances (in form of digitized sound waves) and converting them into computer-readable form.
- Speech synthesis is the reverse process to the recognition. The advances in this area improve the computers' usability for visually impaired people.
- Speech compression is important in the telecommunication area. Scientists aim for better quality at lower bit-rate.
