Volume Adjustment for Voice Agents
You can now control how loud your voice agent sounds. A new Volume slider in the agent’s voice settings (Sarvam / Bulbul voices) sets the loudness of the agent’s speech, from 0.7 (quieter) to 2.0 (louder), with 1.0 as the natural level. The volume is stored with the agent’s voice configuration and applied on every call, so it can be set once and manipulated later. See Speakers & voice.
