Process for evaluating speech quality in speech synthesis
First Claim
1. A process for evaluating speech quality in synthetic speech generated from a speech synthesizer in a speech recognition system programmed using speech from a training group, comprising the steps of:
- receiving synthetic speech from at least one speech synthesizer;
receiving natural speech from a plurality of human sources;
determining a level of recognition for each received speech from the at least one speech synthesizer and plurality of human sources; and
evaluating the synthetic speech from the at least one speech synthesizer by allocating a level of recognition and a rank of the synthetic speech from the at least one speech synthesizer in comparison to the natural speech from the plurality of human sources.

Abstract
The present invention relates to a process for evaluating speech quality in speech synthesizers with the aid of a speech recognition system. The recognition system is programmed using a number of persons. It then receives synthetic or natural speech from speech synthesizers or persons respectively, displaying differing speech quality. The speech recognition system determines a level of recognition for each received speech quality. In order to evaluate the speech quality in a speech synthesizer, speech is received from the synthesizer by the speech recognition system, is allocated a level of recognition and is ranked in comparison to the levels of recognition for previously received speech.

2. A system for evaluating speech quality in synthetic speech generated from a speech synthesizer comprising:
-
at least one speech synthesizer for generating synthetic speech; a speech recognition system programmed using speech from a training group and for receiving the synthetic speech from the at least one speech synthesizer and natural speech from a plurality of human sources; wherein a level of recognition for each received speech from the at least one speech synthesizer and the plurality of human sources is determined; and wherein the synthetic speech from the at least one speech synthesizer is evaluated by allocating a level of recognition and a rank of the synthetic speech from the at least speech synthesizer in comparison to the natural speech from the plurality of human sources.

3. A system for evaluating speech quality in synthetic speech generated from a speech synthesizer comprising:
-
at least one speech synthesizer for generating synthetic speech; a speech recognition system programmed using speech from a training group of a first plurality of human sources and for receiving the synthetic speech from the at least one speech synthesizer and natural speech from a second plurality of human sources; wherein a level of recognition for each received speech from the at least one speech synthesizer and the second plurality of human sources is determined; and wherein the synthetic speech from the at least one speech synthesizer is evaluated by allocating a level of recognition and a rank of the synthetic speech from the at least speech synthesizer in comparison to the natural speech from the second plurality of human sources. - View Dependent Claims (4)
