> deepspeech was evaluated, but right now kaldi provides better performance

Was this before the streaming API was added to DeepSpeech? I recently did some testing with it, and it provides text within ~100ms of last audio block on my PC.

edit: that is, the most significant latency I had was from having to wait a bit to detect end of speech.

with "performance" i meant the error rate, not the speed. speed was not a criteria for us, so we didnt evaluate it. i read that deepspeech is way quicker in training phase as it is smarter in using gpu computing power.

Ahh gotcha. Yes I got rather poor "hit rate" until I made my own language model.

Fortunately for me I only needed it for command recognition, so the process was quite quick, and results were very good. No need to retrain the net.

we used a context-free data set, augmented with additional domain-specific sound samples and it worked out fine, although the additiinal samples made nearly no difference
