Falcon 2 streaming now supports loudness adjustments from -50 to 50 through Stream Speech and WebSocket voice_config.
Murf AI has added volumeOffset to Falcon 2 streaming, letting voice agents adjust loudness for phone lines, earpieces and noisy environments without adding latency.
Setting the volume offset
The setting is supported on Stream Speech and in WebSocket voice_config. It accepts an integer from -50 to 50, with a default of 0, to adjust loudness relative to the model’s default output.
The announcement points to the Volume offset (Falcon 2) documentation and Falcon 2 model page for suggested ranges and best practices.
