HTK-HSGen
The tool HSGen can be used to do this by
randomly traversing a word network and outputting each word encountered. For example, typing
HSGen -l -n 200 wdnet dict > testprompts
would generate 200 numbered test utterances, the first few of which would look something like:
1. PHONE YOUNG
2. DIAL OH SIX SEVEN SEVEN OH ZERO
3. DIAL SEVEN NINE OH OH EIGHT SEVEN NINE NINE
4. DIAL SIX NINE SIX TWO NINE FOUR ZERO NINE EIGHT
5. CALL JULIAN ODELL
... etc
These can be piped to construct the prompt file testprompts for the required test data.
