[null,null,["Last updated 2025-08-27 UTC."],[],["`GMSNavigationVoiceGuidance` controls voice guidance behavior, offering three options. `silent` (0) completely disables voice guidance. `alertsOnly` (1) activates voice guidance solely for traffic alerts. `alertsAndGuidance` (2) enables voice guidance for both turn-by-turn directions and traffic alerts. These are defined in both Swift (`case`) and Objective-C (`GMSNavigationVoiceGuidance`) as `enum` with different `NSInteger` values, allowing developers to customize the level of voice feedback in their applications.\n"]]
