How to set the sample rate (audio quality)

The speech_sample_rate parameter controls the audio quality and size of the generated output.

It is optional — if omitted, the default value is 22050 Hz (high quality).

Supported values:

Sample Rate (Hz)	Audio Quality Description
8000	Basic telephony quality
16000	Good quality voice
22050	Default high-quality audio
24000	Premium audio quality (larger size)
