Core Workflows

1. Generate Speech from Text

Use ELEVENLABS_TEXT_TO_SPEECH to convert text into a downloadable audio file.

Tool: ELEVENLABS_TEXT_TO_SPEECH
Inputs:
  - voice_id: string (required) -- obtain from ELEVENLABS_GET_VOICES
  - text: string (required) -- max ~10,000 chars (most models), 30,000 (Flash/​Turbo v2), 40,000 (v2.5)
  - model_id: string (default "eleven_monolingual_v1") -- e.g., "eleven_multilingual_v2"
  - output_format: string (default "mp3_44100_128") -- see formats below
  - optimize_streaming_latency: integer (0-4; NOT supported with eleven_v3)
  - seed: integer (optional, for reproducibility -- not guaranteed)
  - pronunciation_dictionary_locators: array (optional, up to 3 dictionaries)

Output formats:

• MP3: mp3_22050_32, mp3_44100_32, mp3_44100_64, mp3_44100_96, mp3_44100_128, mp3_44100_192 (Creator+)

• uLaw: ulaw_8000 (for Twilio)

Important: Output is a file object with a presigned download link at data.file.s3url (expires in ~1 hour). Download promptly.

2. Browse Available Voices

Use ELEVENLABS_GET_VOICES to list all voices with their attributes and settings.

Tool: ELEVENLABS_GET_VOICES
Inputs: (none)

Returns an array at data.voices[] with voice_id, name, labels (gender, accent, use_case), and settings.

3. Inspect a Specific Voice

Use ELEVENLABS_GET_VOICE to get detailed metadata for a candidate voice before synthesis.

Tool: ELEVENLABS_GET_VOICE
Inputs:
  - voice_id: string (required) -- e.g., "21m00Tcm4TlvDq8ikWAM"
  - with_settings: boolean (default false) -- include detailed voice settings

4. Check Subscription and Credits

Use ELEVENLABS_GET_USER_SUBSCRIPTION_INFO to verify plan limits and remaining credits before bulk generation.

5. List Available TTS Models

Use ELEVENLABS_GET_MODELS to discover compatible models and filter by can_do_text_to_speech: true.

6. Stream Audio and Retrieve History

Use ELEVENLABS_TEXT_TO_SPEECH_STREAM for low-latency streamed delivery, and ELEVENLABS_GET_AUDIO_FROM_HISTORY_ITEM to re-download previously generated audio.

Tool: ELEVENLABS_TEXT_TO_SPEECH_STREAM
