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+)
PCM: pcm_16000, pcm_22050, pcm_24000, pcm_44100 (Pro+)
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.

Tool: ELEVENLABS_GET_USER_SUBSCRIPTION_INFO
Inputs: (none)

5. List Available TTS Models

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

Tool: ELEVENLABS_GET_MODELS
Inputs: (none)

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
  - Same core inputs as TEXT_TO_SPEECH but returns a stream for low-latency playback

Tool: ELEVENLABS_GET_AUDIO_FROM_HISTORY_ITEM
  - history_item_id: string (required) -- ID from a previous generation

Known Pitfalls

Pitfall	Detail
Text length limits	Most models cap at ~10,000-20,000 chars per request. Oversized input returns HTTP 400. Split long text into chunks (~5000 chars) and generate per chunk.
Output is a presigned URL	`ELEVENLABS_TEXT_TO_SPEECH` returns `data.file.s3url` with a ~1 hour expiry (X-Amz-Expires=3600). Download the audio file promptly.
Quota and credit errors	HTTP 401 with `quota_exceeded` or HTTP 402 `payment_required` means insufficient credits or tier restrictions. Check with `ELEVENLABS_GET_USER_SUBSCRIPTION_INFO` before bulk jobs.
Voice permissions	HTTP 401 with `missing_permissions` means the API key lacks `voices_read` scope. Verify key permissions.
Model compatibility	Not all models support TTS. Use `ELEVENLABS_GET_MODELS` and filter by `can_do_text_to_speech: true`. The `optimize_streaming_latency` parameter is NOT supported with `eleven_v3`.
Large voice list truncation	`ELEVENLABS_GET_VOICES` may return a large list. Select from the full `data.voices[]` payload -- previews may appear truncated.
