System and method of developing a TTS voice
View Patent ↗Disclosed herein are various aspects of a toolkit used for generating a TTS voice for use in a spoken dialog system. The embodiments in each case may be in the form of the system, a computer-readable medium or a method for generating the TTS voice. An embodiment of the invention relates to a method of tracking progress in developing a text-to-speech (TTS) voice. The method comprises insuring that a corpus of recorded speech contains reading errors and matches an associated written text, creating a tuple for each utterance in the corpus and tracking progress for each utterance utilizing the tuple. Various parameters may be tracked using the tuple but the tuple provides a means for enabling multiple workers to efficiently process a database of utterance in preparation of a TTS voice.
1. A method of tracking progress in developing a text-to-speech (TTS) voice, the method comprising:
ensuring that a corpus of recorded speech contains reading errors and matches an associated written text, wherein each of the reading errors comprises at least a half phenome incorrectly matched to a word of the written text;
creating, via a processor, a tuple of files for each utterance in the corpus; and
tracking, via the processor, work done for each utterance utilizing the tuple.
2. The method of claim 1 , wherein each tuple comprises ASR-generated phonemes, pronunciation lists, confidence scores and a progress matrix.
3. The method of claim 2 , wherein the progress matrix stores and tracks work performed on the tuple.
4. The method of claim 3 , wherein the progress matrix further stores information about which person has performed work on the tuple.
5. The method of claim 4 , wherein when different people perform work on each tuple, work-tracking information is stored in the progress matrix such that several people may simultaneously work on the corpus.
6. A tangible computer-readable storage medium storing instructions for controlling a computing device to track progress in developing a text-to-speech (TTS) voice, the instructions comprising:
ensuring that a corpus of recorded speech contains reading errors and matches an associated written text, wherein each of the reading errors comprises at least a half phenome incorrectly matched to a word of the written text;
creating a tuple of files for each utterance in the corpus; and
tracking work done for each utterance utilizing the tuple.
7. The tangible computer-readable storage medium of claim 6 , wherein each tuple comprises ASR-generated phonemes, pronunciation lists, confidence scores and a progress matrix.
8. The tangible computer-readable storage medium of claim 7 , wherein the progress matrix stores and tracks work performed on the tuple.
9. The tangible computer-readable storage medium of claim 8 , wherein the progress matrix further stores information about which person has performed work on the tuple.
10. The tangible computer-readable storage medium of claim 9 , wherein when different people perform work on each tuple, work-tracking information is stored in the progress matrix such that several people may simultaneously work on the corpus.
11. A computing device that tracks progress in developing a text-to-speech (TTS) voice, the computing device comprising:
a processor;
a module configured to control the processor to ensure that a corpus of recorded speech contains reading errors and matches an associated written text, wherein each of the reading errors comprises at least a half phenome incorrectly matched to a word of the written text;
a module configured to control the processor to create a tuple of files for each utterance in the corpus;
a module configured to control the processor to track work done for each utterance utilizing the tuple.
12. The computing device of claim 11 , wherein each tuple comprises ASR-generated phonemes, pronunciation lists, confidence scores and a progress matrix.
13. The computing device of claim 12 , wherein the progress matrix stores and tracks work performed on the tuple.
14. The computing device of claim 13 , wherein the progress matrix further stores information about which person has performed work on the tuple.
15. The computing device of claim 14 , wherein when different people perform work on each tuple, work-tracking information is stored in the progress matrix such that several people may simultaneously work on the corpus.
