Create a Meditation App with AI-Generated Voice A developer published a walkthrough for building a meditation app that uses ElevenLabs' text-to-speech API to generate natural-sounding guided narration. The tutorial covers cloning a voice from a short audio sample to obtain a voice_id, then calling the synthesize endpoint with stability and similarity_boost settings to produce MP3 audio for guided breathing scripts. It includes Python and curl examples for both the voice-cloning and synthesis steps. If you’ve ever built a simple chatbot or a notification system, you’ve already worked with APIs, authentication, and the occasional rate limit. Adding a real‑time, natural‑sounding voice turns a text‑based experience into something that feels comforting, personal, and almost therapeutic. For meditation, that’s a game‑changer: a gentle narrator can guide breathing, set intentions, or play ambient sounds—all while keeping your users engaged. In this post we’ll walk through: By the end, you’ll have a working prototype that you can extend into a full‑featured meditation app. Text‑to‑speech TTS is a mature field, but most free or open‑source solutions lag behind commercial providers in naturalness, voice variety, and developer experience. ElevenLabs offers: If you’re looking for a quick, production‑ready voice solution, check out ElevenLabs at https://try.elevenlabs.io/kr07zfuqn1bp https://try.elevenlabs.io/kr07zfuqn1bp . The free tier is generous, and you can upgrade to a paid plan for higher quality and more requests. A generic “calm” voice can work, but a cloned voice that mimics the user’s own voice or a brand‑specific narrator creates a deeper connection. ElevenLabs’ cloning workflow is simple: voice id . Below is a quick Python script to upload a clip and get the voice id : python import os import requests API KEY = os.getenv "ELEVENLABS API KEY" UPLOAD URL = "https://api.elevenlabs.io/v1/voices" headers = {"xi-api-key": API KEY, "Accept": "application/json"} 1️⃣ Record a short sample e.g., 30s and save as sample.wav with open "sample.wav", "rb" as audio: files = {"file": "sample.wav", audio, "audio/wav" } response = requests.post f"{UPLOAD URL}/clone", headers=headers, files=files if response.ok: voice id = response.json "voice id" print "Your cloned voice ID:", voice id else: print "Error:", response.text Remember to keep the audio file under 3 MB for the free tier. If you need larger samples, upgrade your plan. Once you have a voice id , you can use it in subsequent synthesis calls to produce a voice that sounds like the original speaker. A typical meditation routine might consist of: We’ll generate these on demand using ElevenLabs’ synthesize endpoint. python import os import requests API KEY = os.getenv "ELEVENLABS API KEY" VOICE ID = os.getenv "VOICE ID" The cloned voice ID you got earlier TTS URL = f"https://api.elevenlabs.io/v1/text-to-speech/{VOICE ID}" headers = { "xi-api-key": API KEY, "Content-Type": "application/json" } def synthesize text, output path="output.mp3" : payload = { "text": text, "voice settings": { "stability": 0.5, 0-1.0 "similarity boost": 0.75 } } response = requests.post TTS URL, headers=headers, json=payload, stream=True if response.status code == 200: with open output path, "wb" as f: for chunk in response.iter content chunk size=8192 : f.write chunk print f"Saved audio to {output path}" else: print "Synthesis failed:", response.text Demo: a short guided breathing session script = """ Welcome. Let's take a moment to settle in. Close your eyes, and breathe in slowly through your nose. Hold for a count of three. Now exhale gently through your mouth. Repeat this cycle for a few minutes. """ synthesize script This script pulls the voice model from ElevenLabs and writes the resulting MP3 to disk. You can adapt the synthesize function to stream audio directly to a mobile app or a web player. curl for Quick Tests If you prefer the CLI: curl -X POST "https://api.elevenlabs.io/v1/text-to-speech/$VOICE ID" \ -H "xi-api-key: $ELEVENLABS API KEY" \ -H "Content-Type: application/json" \ -d '{ "text": "Hello from ElevenLabs This is a test of the TTS engine.", "voice settings": { "stability": 0.5, "similarity boost": 0.75 } }' --output test.mp3 Let’s assume you’re building a React Native app. The simplest way to play synthesized audio is to: expo-av or react-native-sound . Here’s a quick React Native snippet: python import React, { useEffect } from 'react'; import { View, Button } from 'react-native'; import { Audio } from 'expo-av'; export default function MeditationScreen { const playAudio = async = { const { sound } = await Audio.Sound.createAsync { uri: 'https://your-backend.com/audio/meditation.mp3' }, { shouldPlay: true } ; // Optionally unload when finished sound.setOnPlaybackStatusUpdate status = { if status.didJustFinish { sound.unloadAsync ; } } ; }; return
