Just ran some tests on my phrases:

- my whistle setup (tested can run on echo show with <1s response): 206 correct out of 208

These were not tested on echo show yet - on my pc for now:

- Vosk small, phrase grammar: 184/208

- Speech-to-Phrase 1.4.3 (Kaldi): 118/208

- suggested sphinx: 63/208 and on some examples took 13s on i7 14700k pc

looks like my customized whistle works better for me than these alternatives. But more testing wouldn't hurt.
