int
Sample rate in Hertz of the audio data sent for recognition.
Valid values are: 8000-48000. 16000 is optimal. For best
results, set the sampling rate of the audio source to 16000
Hz. If that's not possible, use the native sample rate of
the audio source (instead of re-sampling). Supported for the
following encodings:
- LINEAR16: Headerless 16-bit signed little-endian PCM
samples.
- MULAW: Headerless 8-bit companded mulaw samples.
- ALAW: Headerless 8-bit companded alaw samples.
audio_channel_count
int
Number of channels present in the audio data sent for
recognition. Supported for the following encodings:
- LINEAR16: Headerless 16-bit signed little-endian PCM
samples.
- MULAW: Headerless 8-bit companded mulaw samples.
- ALAW: Headerless 8-bit companded alaw samples.
The maximum allowed value is 8.
