1. A method for determining speech quality, comprising the steps of:
- providing a first speech;
providing a second speech, wherein said second speech is a reproduction of said first speech; and
determining time differences between corresponding starts of each vowel sound of each word in said first and second speech, wherein said time differences are a measure of a match of said first speech and said second speech and providing an output of said time differences.

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.
