Generate lifelike, expressive speech directly through fal's serverless infrastructure using Eleven v3, ElevenLabs' most advanced speech synthesis model. Eleven v3 delivers natural, emotionally-aware audio with broad dynamic range, inline audio tag control, and support for 70+ languages — all available through a single fal endpoint: fal-ai/elevenlabs/tts/eleven-v3.
Eleven v3 is ElevenLabs' flagship text-to-speech model, designed for the most expressive and emotionally nuanced AI-generated speech available today. Unlike earlier models, Eleven v3 offers a broad dynamic range controlled through inline audio tags — descriptive markers like [whispers], [laughs], [excited], or [sad] that the model interprets to shape delivery, emotion, tempo, and tone.
Key capabilities of Eleven v3:
[laughs], [whispers], [sighs], [excited], [sarcastically], and many more)text-to-dialogue/eleven-v3 endpointEleven v3 is the clear choice when expressive delivery matters most. For ultra-low-latency conversational use cases, pair it with Flash or Turbo v2.5; for pure multilingual narration with classic stability, Multilingual v2 remains a solid alternative.
ElevenLabs is an AI audio research and deployment company founded in 2022 by Piotr Dąbkowski (ex-Google ML engineer) and Mati Staniszewski (ex-Palantir). Headquartered in London and New York, the company has become the dominant platform in voice AI — according to recent market analysis, ElevenLabs accounts for approximately 98% of observed mid-market voice AI spend and is the entry point for 95% of first-time voice AI customers.
The company's platform spans text-to-speech, speech-to-text (Scribe), voice cloning (Instant and Professional), voice design, dubbing, music generation, and real-time conversational AI agents. ElevenLabs raised $500M at an $11B valuation in early 2026 and crossed $330M in annual recurring revenue in 2025.
ElevenLabs is used by 41% of Fortune 500 companies and a diverse set of industry leaders:

Basic synchronous call:
javascriptimport { fal } from "@fal-ai/client"; const result = await fal.subscribe("fal-ai/elevenlabs/tts/eleven-v3", { input: { text: "Hello! This is a test of the text to speech system, powered by ElevenLabs.

Eleven v3 on fal supports streaming for real-time audio playback:
javascriptimport { fal } from "@fal-ai/client"; const stream = await fal.stream("fal-ai/elevenlabs/tts/eleven-v3", { input: { text: "Hello! This is a test of the text to speech system, powered by ElevenLabs." } }); for await (const event of stream) { console.log(event); } const result = await stream.done();
For long-form generation (audiobooks, podcasts, large batches), use the queue API with an optional webhook to receive completion notifications:
javascriptimport { fal } from "@fal-ai/client"; // Submit const { request_id } = await fal.queue.submit("fal-ai/elevenlabs/tts/eleven-v3", { input: { text: "Long-form narration goes here..." }, webhookUrl: "https://your-app.com/webhooks/tts-complete", }); // Check status later const status = await fal.queue.status("fal-ai/elevenlabs/tts/eleven-v3", { requestId: request_id, logs: true, }); // Fetch the result const result = await fal.queue.result("fal-ai/elevenlabs/tts/eleven-v3", { requestId: request_id });
Eleven v3's standout feature is inline audio tag control. Add bracketed directives anywhere in your text to shape how it's performed:
Emotional tags
[happy] [sad] [excited] [angry] [sarcastically] [nervous] [confident]
Delivery tags
[whispers] [shouting] [slowly] [quickly] [softly]
Non-verbal sounds
[laughs] [chuckles] [sighs] [gasps] [coughs] [gulps] [applause]
Accent tags
[strong canadian accent] [british accent] [southern accent]
Example:
text[slowly] Back then... [chuckles] we had no phones. [whispers] Just dirt roads and [coughs] big dreams. [sad] Then it happened.
Audio tags are voice- and context-dependent — some voices interpret certain tags more reliably than others. Experiment to find what works best for your use case.
Eleven v3's expressive range and multilingual reach make it well-suited for high-production-value audio work:
If Eleven v3 isn't the right fit, fal also hosts other ElevenLabs endpoints:
fal-ai/elevenlabs/text-to-dialogue/eleven-v3 — multi-speaker dialogue generation with matched prosodyfal-ai/elevenlabs/tts/multilingual-v2 — stable, high-quality narration across 29 languagesfal-ai/elevenlabs/tts/turbo-v2.5 — lowest-latency option, ideal for real-time agents
