I noticed that small english 0.15 version has rather poor performance (compared to whisper tiny/base). Could you please add model vosk-model-small-en-us but 0.22 version (for portable devices, android, RPi). I don't mean vosk-model-en-us-0.22-lgraph whose performance is also very average. I would like to point out, however, in case of Polish language your model vosk-model-small-pl-0.22 is simply fantastic, in my opinion much better than whisper tiny/small and works much faster. So I guess english 0.22 small version would be also much better, unfortunately base version (vosk-model-en-us-0.22) is too big (1.8G) for portable devices.
