Abstract
Auditory-articulatory analysis for use in speech quality assessment. Articulatory analysis is based on a comparison between powers associated with articulation and non-articulation frequency ranges of a speech signal. Neither source speech nor an estimate of the source speech is utilized in articulatory analysis. Articulatory analysis comprises the steps of comparing articulation power and non-articulation power of a speech signal, and assessing speech quality based on the comparison, wherein articulation and non-articulation powers are powers associated with articulation and non-articulation frequency ranges of the speech signal.
Claims16
A method of performing auditory-articulatory analysis comprising the steps of:
- comparing articulation power and non-articulation power for a speech signal, wherein articulation and non-articulation powers are powers associated with articulation and non-articulation frequencies of the speech signal;
- and
- and assessing speech quality based on the comparison.
