Pocketsphinx&#x2F;Sphinx with a small, use-case specific dictionary showed much better accuracy for my accent and speech defects, than any of these cloud based recognition systems. I used a standard acoustic model, but it probably would have been even more accurate had I trained a custom acoustic model.<p>For simple use cases like home automation or desktop automation, I think it&#x27;s a more practical approach than depending on a cloud API.
