METHOD, COMPUTER, COMPUTER PROGRAM AND COMPUTER PROGRAM PRODUCT FOR SPEECH QUALITY ESTIMATION

摘要

The invention relates to a method, computer, computer program and computer program product for speech quality estimation. The method comprises the steps of: determining a coding distortion parameter (QCOD), a bandwidth related distortion parameter (BW) and a presentation level distortion parameter (PL) of a speech signal; extracting a first coefficient (omegal) and a second coefficient (omega2), the first coefficient and the second coefficient being dependent on the coding distortion parameter; and calculating a signal quality measure (Q), where the signal quality measure is QCOD+omega1BW+omega2PL using the signal quality measure in a quality estimation of the speech signal.
