16kHz sample rate does not work about vosk-browser HOT 2 CLOSED

The issue is most likely that some browser will not provide media at 16kHz (they ignore the samplerate parameter) and fallback to 48kHz. However you are telling vosk when creating the recognizer that audio will be streamed at 16kHz. You are thus sending 48kHz audio to a recognizer expecting 16kHz, which is why it does not work.

We can’t change the sample rate of the recording device but, if I recall correctly, we can manually specify the sample rate for the audio context and the browser would automatically downsample (using the Web Audio API) the audio data. I verified that I was indeed getting 16kHz PCM audio data by inspecting the waveform of a sine wave at a fixed and known frequency.

UPDATE
The demo does indeed work with 16kHz. Nevermind.
