How this service works
ElevenLabs v3 dialogue (dynamic pricing)
Output
Returns a request_id immediately upon submission. The agent must poll the fal.ai queue status endpoint with the request_id to retrieve the final result, which includes a URL or binary payload of the synthesized dialogue audio file once generation is complete.
Example use cases
Podcast intro dialogue generation
“Take this podcast intro script with two hosts — Alex says 'Hey everyone, welcome back!' and Jamie replies 'So excited for today's episode!' — and generate realistic dialogue audio using ElevenLabs v3 as an async job I can retrieve when it's ready.”
Game NPC conversation voiceover
“I need audio for an NPC dialogue in my game: the guard says 'Halt! Who goes there?' and the merchant replies 'Just a humble trader, sir.' Can you generate that as expressive spoken dialogue using ElevenLabs v3 and queue it asynchronously?”
Audiobook multi-character scene
“Generate a spoken audio version of this short scene — Narrator: 'She knocked on the door.', Character 1: 'Come in.', Character 2: 'Is it safe?' — using ElevenLabs v3 dialogue synthesis, submitted to the async queue so I can fetch the result once it's done.”
Technical details
Endpoint
POSThttps://fal-queue.mpp.tempo.xyz/fal-ai/elevenlabs/text-to-dialogue/eleven-v3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to synthesize multi-speaker dialogue audio using ElevenLabs' latest expressive v3 model and the generation may exceed real-time sync timeouts (~100s). Ideal for longer scripts, complex multi-turn conversations, or batch audio production pipelines where async polling is acceptable. Prefer over synchronous alternatives when output quality (ElevenLabs v3 expressiveness) matters more than latency.
Side effects
- Invalid or missing text input returns a 422 validation error
- Queue timeout if the generation job takes too long on the backend
- Polling for a non-existent or expired request_id returns a 404
- Unsupported speaker configuration or voice parameters may cause a generation failure
- Dynamic pricing may cause payment authorization to fail if budget is insufficient
