It can be seen that, for voice over SCO, average recognition accuracy goes from 55% in case of a low quality link to 84% in case of a high quality link. For voice over ACL, average recognition accuracy is 94% regardless of link quality, because the speech is transferred without errors.
In this paper we have investigated speech recognition performance for voice transferred over ACL and SCO links at various channel qualities. Our experiments ...
