ElevenLabs Core Workflow B — Speech-to-Speech, Sound Effects & Audio Isolation

Overview

Secondary ElevenLabs workflows beyond TTS: (1) Speech-to-Speech voice conversion, (2) Sound Effects generation from text descriptions, (3) Audio Isolation for noise removal, and (4) Speech-to-Text transcription. Each maps to one API endpoint and has both a TypeScript SDK and a cURL path.

Full code for every step lives in references/implementation.md; copy-ready invocations are in references/examples.md.

Prerequisites

• Completed elevenlabs-install-auth setup.
• For STS: source audio file in MP3/WAV/M4A format.
• For audio isolation: noisy audio file to clean.

Authentication

The SDK client (new ElevenLabsClient()) reads the API key from the ELEVENLABS_API_KEY environment variable automatically — never hardcode it. cURL requests send it as the xi-api-key: ${ELEVENLABS_API_KEY} header. Full auth setup is covered by the elevenlabs-install-auth skill.

Instructions

Import the SDK once, then call the relevant module. The client authenticates from the environment:

import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js";
import { createReadStream, createWriteStream } from "fs";
import { Readable } from "stream";
import { pipeline } from "stream/promises";

const client = new ElevenLabsClient();

1. Speech-to-Speech (voice changer) — client.speechToSpeech.convert(voiceId, …) against POST /v1/speech-to-speech/{voice_id}. Use model_id: "eleven_english_sts_v2" and set remove_background_noise: true for built-in cleanup.
2. Sound Effects — client.textToSoundEffects.convert({ text, … }) against . Tune (0.5–30) and (0–1; higher follows the prompt more closely).
