Voice Volume sets how loud or soft the AI sounds during a call. This controls gain—not energy or tone—so you can match the AI’s voice level to different environments, hardware setups, or user preferences.
Lower values (<1): softer output, useful for background blending or quieter devices.
Higher values (>1): louder projection, ideal for noisy settings or low speaker gain.
Value of 1.0 delivers neutral, calibrated output—safe for most systems.
