Our AI model produces the highest-quality AI voices in the industry. Here is an example of one of our default voices Grace in action:

Our text to speech API allows you to convert text into audio in 29 languages and 1000s of voices. Integrate our realistic text to speech voices into your react app, use our Python library or our websockets guide to get started.

API Features

High-quality voices

1000s of voices, in 29 languages, for every use-case, at 128kbps

Ultra-low latency

Achieve ~400ms audio generation times with our Turbo model.

Contextual awareness

Understands text nuances for appropriate intonation and resonance.

Quick Start


In order to use our API you need to get your xi-api-key first. Create an account, log in and in the upper right corner click on your profile picture -> profile.

Visit profile

Next click on the eye icon on your profile to access your xi-api-key. Do not show your account to anyone else. If someone gains access to your xi-api-key he can use your account as he could if he knew your password.

You can generate a new xi-api-key at any time by clicking on the spinning arrows next to the text field. This will invalidate your old xi-api-key.

Audio generation

Generate spoken audio from text with a simple request like the following python example:

import requests

url = "<voice-id>"

headers = {
  "Accept": "audio/mpeg",
  "Content-Type": "application/json",
  "xi-api-key": "<xi-api-key>"

data = {
  "text": "Born and raised in the charming south, 
  I can add a touch of sweet southern hospitality 
  to your audiobooks and podcasts",
  "model_id": "eleven_monolingual_v1",
  "voice_settings": {
    "stability": 0.5,
    "similarity_boost": 0.5

response =, json=data, headers=headers)
with open('output.mp3', 'wb') as f:
    for chunk in response.iter_content(chunk_size=CHUNK_SIZE):
        if chunk:


We offer 1000s of voices in 29 languages. Visit the Voice Lab to explore our pre-made voices or clone your own. Visit the Voices Library to see voices generated by ElevenLabs users. Below are some of our most popular voices:


Supported languages

Our TTS API is multilingual and currently support the following languages:

Chinese, Korean, Dutch, Turkish, Swedish, Indonesian, Filipino, Japanese, Ukrainian, Greek, Czech, Finnish, Romanian, Russian, Danish, Bulgarian, Malay, Slovak, Croatian, Classic Arabic, Tamil, English, Polish, German, Spanish, French, Italian, Hindi and Portuguese.

To use them, simply provide the input text in the language of your choice.



Your API key. This is required by most endpoints to access our API programatically. You can view your xi-api-key using the 'Profile' tab on the website.

Path Parameters


Voice ID to be used, you can use to list all the available voices.

Query Parameters

default: 0

You can turn on latency optimizations at some cost of quality. The best possible final latency varies by model. Possible values: 0 - default mode (no latency optimizations) 1 - normal latency optimizations (about 50% of possible latency improvement of option 3) 2 - strong latency optimizations (about 75% of possible latency improvement of option 3) 3 - max latency optimizations 4 - max latency optimizations, but also with text normalizer turned off for even more latency savings (best latency, but can mispronounce eg numbers and dates).

Defaults to 0.

default: mp3_44100_128

Output format of the generated audio. Must be one of: mp3_22050_32 - output format, mp3 with 22.05kHz sample rate at 32kbps. mp3_44100_32 - output format, mp3 with 44.1kHz sample rate at 32kbps. mp3_44100_64 - output format, mp3 with 44.1kHz sample rate at 64kbps. mp3_44100_96 - output format, mp3 with 44.1kHz sample rate at 96kbps. mp3_44100_128 - default output format, mp3 with 44.1kHz sample rate at 128kbps. mp3_44100_192 - output format, mp3 with 44.1kHz sample rate at 192kbps. Requires you to be subscribed to Creator tier or above. pcm_16000 - PCM format (S16LE) with 16kHz sample rate. pcm_22050 - PCM format (S16LE) with 22.05kHz sample rate. pcm_24000 - PCM format (S16LE) with 24kHz sample rate. pcm_44100 - PCM format (S16LE) with 44.1kHz sample rate. Requires you to be subscribed to Independent Publisher tier or above. ulaw_8000 - μ-law format (sometimes written mu-law, often approximated as u-law) with 8kHz sample rate. Note that this format is commonly used for Twilio audio inputs.


default: eleven_monolingual_v1

Identifier of the model that will be used, you can query them using GET /v1/models. The model needs to have support for text to speech, you can check this using the can_do_text_to_speech property.


A list of pronunciation dictionary locators (id, version_id) to be applied to the text. They will be applied in order. You may have up to 3 locators per request


The text that will get converted into speech.


Voice settings overriding stored setttings for the given voice. They are applied only on the given request.


200 - audio/mpeg

The response is of type file.
