Virtual Test Instrumental System of Speech Quality Assessment for Vocoder

摘要

As the speech vocoder system is more and more complex, there is a great demand for speech quality assessment tests and measures. In this paper, a overall virtual test instrumental system of speech quality assessment for vocoder is presented, at the same time the research on theory and the implementation of speech quality assessment is carried out. As a test and assessment platform, the system is designed for various scenario, which has passed all of the user's tests and requirements recently. Experimental results verified that the methods mentioned above are reasonable and feasible.
