ElevenLabs V3 - Audio Tags

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

What’s new

• 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.

How to use it

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).

API changes

• 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.
