Speech signal processing

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.
