Evaluation objective de la qualité vocale en contexte de conversation

Abstract : Speech quality is a huge issue for telecommunications operators: they have to evaluate it to satisfy their customers. Subjective methods assess human perception directly but they are expensive to conduct. Objective methods have been conceived to replace them. An objective model is proposed to assess conversational speech quality from the listening, talking and interaction qualities. This model comprises two parts: the integration function combines the listening, talking and interaction quality scores to estimate conversational quality score and the measurement function provides to the integration function the objective quality scores obtained from the existing models in the various contexts. Four subjective tests studying several degradations of the conversational speech quality have been designed to build and validate the integration function. The model is applied to real signals and achieves high performance.
