This skill covers the core `POST /v1/text-to-speech/{voice_id}` endpoint with real voice IDs, model selection, and audio output. ## Prerequisites - Completed `elevenlabs-install-auth` setup - Valid API key in `ELEVENLABS_API_KEY` ## Instructions ### Step 1: Text-to-Speech with the SDK **TypeScript (recommended):** ```typescript import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js"; import { createWriteStream } from "fs"; import { Readable } from "stream"; import { pipeline } from "stream/promises"; const client = new ElevenLabsClient(); async function generateSpeech() { // Use a pre-made voice — "Rachel" is a default voice available on all accounts // Find voice IDs via: GET /v1/voices const audio = await client.textToSpeech.convert("21m00Tcm4TlvDq8ikWAM", { text: "Hello! This is your first ElevenLabs text-to-speech generation.", model_id: "eleven_multilingual_v2", // Best quality, 29 languages voice_settings: { stability: 0.5, // 0-1: lower = more expressive similarity_boost: 0.75, // 0-1: higher = closer to original voice style: 0.0, // 0-1: higher = more dramatic (costs more latency) speed: 1.0, // 0.7-1.2: speech speed multiplier }, }); // audio is a ReadableStream — pipe to file await pipeline( Readable.fromWeb(audio as any), createWriteStream("output.mp3") ); ...
