ElevenLabs V3 - Audio Tags

Synthflow now supports ElevenLabs V3 as a voice model, bringing inline audio tag control to your agents.

Global audio tags — Set a persistent voice character for the entire call, such as [American accent] or [warm and friendly tone], via the new Global Audio Tags field in Voice Configuration or the global_audio_tags API parameter.
Situational audio tags — Place tags like [excited], [whispers], [laughs], and [sighs] inline in your prompts to control delivery at specific moments. Each tag affects approximately 4-5 words before returning to normal delivery.

Select ElevenLabs V3 as the voice model in Voice Configuration and start using audio tags in your prompts. See the full guide: Audio Tags (ElevenLabs V3).

voice_synthesizer now accepts eleven_v3 as a valid value.
New optional global_audio_tags field on the Agent object for setting persistent voice tags via the API.
