Because the subjective evaluation of speech intelligibility in degraded communications systems is very time consuming, an objective measure would be a valuable tool. This paper shows that a simple extension of ITU-T Recommendation P.862 achieves at least a 0.8 correlation between subjective and objective intelligibility scores. Additional enhancements raised the correlation to around 0.9. Tests used CVC words embedded in a carrier sentence in the subjective test and a concatenated CVC string in the objective PESQ measurements.
