Abstract :
The effect of phone-level speaking rate on speech recogniser performance is investigated. It is shown that deviation from the mean phone-level rate is correlated with the phone recognition error, and that the interval length for rate calculation is important, with optimal values of approximately four and 15 phones. A rate compensation algorithm is proposed
