Short description

Speech enhancement algorithms can be evaluated using either subjective or objective methods. Subjective methods have the drawback that they are time-consuming, laborious, and expensive. Nevertheless listening tests are essential to evaluate quality, intelligibility and pleasantness of enhanced speech, especially electro-larynx speech.

There are standards and recommendations for subjective evaluation of speech signals (MUSHRA, CCR) but they have never been examined in terms of their applicability to electro-larynx speech.
