--- name: elevenlabs description: Agent-callable ElevenLabs tools — generate spoken audio from text, create sound effects and multi-speaker dialogue, re-voice and clean up audio, transcribe audio and video, design synthetic voices, and manage voices, history, and quota. Use when the user mentions ElevenLabs or wants AI audio work — text to speech, narration, voiceover, transcription, voice changing, or sound design — even if they don't name ElevenLabs explicitly, e.g. "read this aloud", "make an MP3 of this", "transcribe this recording". license: Elastic-2.0 compatibility: Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options. metadata: source: https://github.com/zapier/connectors/blob/main/apps/elevenlabs/SKILL.md title: Elevenlabs api-docs: https://elevenlabs.io/docs/api-reference/introduction zapier-app-key: App226160CLIAPI --- # Elevenlabs _Independent, unofficial connector for Elevenlabs. Not affiliated with, endorsed by, or sponsored by Elevenlabs. "Elevenlabs" is a trademark of its owner, used only to identify the service this connector works with._ Tools for the ElevenLabs AI-audio API: convert text to spoken audio in any of the account's voices, generate sound effects and multi-speaker dialogue, re-voice or denoise existing audio, transcribe audio and video by URL, design brand-new synthetic voices from a text description, and manage the account's voices, generation history, and credit quota. Audio-producing tools write the audio to a local file and return its path by default; pass `return_base64: true` to get the bytes inline instead (for consumers without filesystem access). ## When to use this - Turn text into audio: narration, a spoken reply, a podcast-style dialogue, or a sound effect described in words. - Transform existing audio: transcribe it, isolate the speech from background noise, or re-voice it in a different voice. - Manage voices: find one in the account or the community library, add it, design a new one from a description, or free up voice slots. - Check the account before big generations: remaining character credits, tier gates, and voice-slot usage via `getUserSubscription`. ## Setup This is an [agentskills.io](https://agentskills.io) skill. If the connector has not been installed as a skill yet, install it first with `npx skills add zapier/connectors --skill elevenlabs` (or your harness's own skill-install mechanism), then continue here. The connector runs on **Node.js 22.18+**. Pick the reference that matches how you're running it, and load it before doing anything else: | You have... | Load | | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------ | | An MCP-aware client — tools may already be loaded (e.g. `mcp__elevenlabs__`), or you can register a local server yourself (or guide the user to) | [`references/use-as-mcp.md`](references/use-as-mcp.md) | | Terminal / subprocess access (you can run `node`) | [`references/use-as-cli.md`](references/use-as-cli.md) | | Only your own code, importing this package as a dependency | [`references/use-as-sdk.md`](references/use-as-sdk.md) | | No tool access, no terminal, no ability to import this package — you write your own code that calls the ElevenLabs API directly (e.g. a code-execution sandbox) | [`references/use-as-recipe.md`](references/use-as-recipe.md) | ## Scripts All scripts share the single `elevenlabs` connection. Audio-producing scripts accept `return_base64` (default false: audio is written to a temp file and returned as `audio_path`). | Script | Script name | Connections | Description | | ---------------------------------- | ----------------------- | ----------- | --------------------------------------------------------------------------------------------- | | `scripts/textToSpeech.ts` | `textToSpeech` | elevenlabs | Convert text to spoken audio in a chosen voice (resolve `voice_id` via `listVoices`). | | `scripts/createSoundEffect.ts` | `createSoundEffect` | elevenlabs | Generate a sound effect (not speech) from a text description. | | `scripts/textToDialogue.ts` | `textToDialogue` | elevenlabs | Generate a multi-speaker conversation from a list of `{ text, voice_id }` lines. | | `scripts/speechToSpeech.ts` | `speechToSpeech` | elevenlabs | Re-voice existing speech in a different voice; source is an HTTPS URL or local path. | | `scripts/isolateAudio.ts` | `isolateAudio` | elevenlabs | Remove background noise/music from a recording; source is an HTTPS URL or local path. | | `scripts/speechToText.ts` | `speechToText` | elevenlabs | Transcribe audio/video from an HTTPS URL, with timestamps and speaker labels. | | `scripts/designVoice.ts` | `designVoice` | elevenlabs | Design a new synthetic voice from a text description; returns candidate previews. | | `scripts/createVoiceFromDesign.ts` | `createVoiceFromDesign` | elevenlabs | Save a designed voice (by `generated_voice_id` from `designVoice`) to the account. | | `scripts/listVoices.ts` | `listVoices` | elevenlabs | List the account's voices — the `voice_id` resolver. | | `scripts/getVoice.ts` | `getVoice` | elevenlabs | Get one voice's full metadata by id. | | `scripts/searchVoiceLibrary.ts` | `searchVoiceLibrary` | elevenlabs | Search the community voice library by name, language, gender, age, accent. | | `scripts/addSharedVoice.ts` | `addSharedVoice` | elevenlabs | Add a community library voice to the account (uses a voice slot). | | `scripts/deleteVoice.ts` | `deleteVoice` | elevenlabs | Remove a voice from the account; frees a voice slot.

Before generating with, deleting, or adding a voice matched by name: count exact (case-insensitive) name matches. Exactly one → act on it without asking. Two or more → stop, list the candidates with a distinguishing field (category, description, or accent), and ask which one. Never silently pick. The same rule applies to history items matched by their source text via `listHistory` search before `deleteHistoryItem`. **Unsupported operations.** This connector does not clone voices from sample recordings (instant or professional voice cloning) and does not generate music. If asked, say the operation isn't supported here and stop — don't substitute `designVoice` (which invents a voice from a description, not from someone's recording) or `createSoundEffect` (which makes sound effects, not music) and report success for an action you didn't perform. ## Auth Every shape passes auth as one connection **selector**, not the secret — a `[:]` string. Every connector accepts `zapier:` (Zapier-managed auth — routes through Zapier's auth, retries, and governance layer); some also accept one or more direct-token resolvers (naming and count vary per connector) — check this connector's own resolvers rather than assuming. The `:` prefix is optional; a bare value goes to the first resolver that claims it. Each script declares the connections it needs and the resolvers each accepts. The exact syntax for passing a connection (and how to see this connector's resolver list) differs by shape — see the reference you loaded above. Two resolvers serve the `elevenlabs` connection: - **`zapier:`** — Zapier-managed auth. The connection id points at an ElevenLabs connection in your Zapier account (create one at zapier.com if needed); Zapier injects the API key per request, so no third-party secret enters the agent's environment. A bare UUID-shaped value is claimed by this resolver automatically. - **`env:`** — direct mode. `` names an environment variable holding an ElevenLabs API key (create one at elevenlabs.io → Settings → API keys); the connector sends it as the API's `xi-api-key` header. `ELEVENLABS_API_KEY` is the conventional name, but any env-var name works. ElevenLabs API keys can be restricted per surface (text-to-speech, voices, history, …) and can carry a quota cap — a valid key can still get a 401 on an endpoint outside its granted permissions, so check the key's permissions before assuming it's dead. Zapier-managed connections can't forward multipart request bodies yet, so the three audio-upload tools — `speechToSpeech`, `speechToText`, and `isolateAudio` — require direct mode (`env:`). All other tools work over either resolver. ## Output format Every script returns a `{ data, meta }` envelope: - **`data`** — the script's result (the shape its `outputSchema` declares; see the reference you loaded above for how to inspect a script's exact schema in your shape). - **`meta.outputDataValidation`** — what validating `data` did: - `{ skipped: false, droppedPaths: null }` — validated, nothing removed. - `{ skipped: false, droppedPaths: [...], instruction }` — validated, but those paths were stripped from `data`: fields the script returned from the API that the `outputSchema` doesn't declare. If you need them, re-run with output validation skipped. - `{ skipped: true }` — validation was bypassed; `data` is the raw, unchecked script output. **Reading dropped fields / `skipOutputDataValidation`.** To receive the raw, unvalidated result, opt out of output validation (the exact syntax differs by shape — see the reference you loaded above). Input validation is never skipped. **Trimming the result / `filterOutputData`.** To shrink a large result down to the fields you need, pass a jq expression that post-processes `data` (again, exact syntax per shape). The jq runs against `data` only, NOT the `{ data, meta }` envelope, so write it rooted at `data` (run the script's `--help` — or your shape's equivalent — to see its output schema). The transformed value replaces `data`, `meta` is preserved, and the result is NOT re-validated against the output schema. ## References Load the matching reference file before working in that area: | Reference | Covers | Load it when | | -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------- | | [ElevenLabs API gotchas](references/elevenlabs-api-gotchas.md) | Authentication, errors, model and voice resolution, generation limits, transcription, pagination, and history | Choosing IDs or models, preparing audio inputs, paginating results, or recovering from API errors |
