Abstract
A method and device for determining quality of speech. The speech to be evaluated is listened to by a person who reproduces the speech. The end of vowel sounds in the produced and reproduced speech respectively are determined. The difference between the ends of the vowel sounds is registered. From the obtained time differences an average value is determined. The average value indicates the quality of the produced speech. The invention can be used for evaluation of different speech sources.
