How to Use AI for Text-to-Speech in React Native? (Code + GitHub Inside)

What if your app could speak like a human?

We’re not talking about robotic voices from the 2020s.

We mean lifelike, expressive, multilingual voices powered by AI. In 2025, AI text-to-speech in React Native is expected.

From meditation apps to voice-based productivity tools, users want more natural interaction. That’s where React Native TTS (Text-to-Speech) excels.

When combined with AI, it allows developers to build apps that talk back, improving accessibility, engagement, and UX.

And with mobile usage at an all-time high, allowing real-time speech in your cross-platform React Native app gives your product a competitive advantage.

If you are trying to use AI for Text to Speech in React Native, then you are at the right place.

Here you have the complete GitHub code for React Native TTS with AI and a guide for it.

What Is AI Text-to-Speech (TTS)? And Why Not Native TTS?

Text-to-Speech with AI goes beyond just reading words aloud.

Unlike traditional or native TTS, which sounds robotic and monotone, AI-based speech synthesis in React Native uses deep learning models to create lifelike speech that adjusts pitch, emotion, and rhythm, just like a real human.

Here’s the difference:

Use Cases:

• Voice assistants
• Language learning apps
• Accessibility tools
• Chatbots with voice output
• Educational apps for kids

So if you want your app to communicate with clarity, emotion, and accuracy, AI TTS is the way forward.

Why Use React Native for AI Text-to-Speech Integration?

React Native is already known for its cross-platform power, and it’s a natural fit for integrating AI TTS features. Here’s why:

• One codebase for iOS and Android.
• Fast development cycles with access to native APIs.
• Easy integration with AI services like Google Cloud, OpenAI, or Amazon Polly.

With tools like react-native-tts, expo-speech, or direct API access, developers can build apps that talk to users in real-time, which is perfect for:

• Productivity tools that read out tasks.
• Accessibility apps for visually impaired users.
• AI chatbots that speak in responses.
• Voice-based surveys or guides.

Choosing the Right AI TTS Provider: Google, OpenAI, or Amazon Polly?

If you’re adding AI TTS APIs to React Native, choosing the right provider is crucial. Let’s compare the top options:

For most mobile apps, Google Cloud Text-to-Speech is a go-to option due to its realistic WaveNet voices, speed, and wide support.

Use these AI TTS APIs for React Native to build apps that truly connect with users, especially when spoken communication matters.

Step-by-Step: Set Up Your React Native Project for TTS

Before we write a single line of code, let’s set up your environment for integrating AI Text-to-Speech in React Native.

Here you can see the exact setup needed to follow along with the React Native text to speech code example and fork our TTS GitHub demo.

Tools Required:

• Node.js ≥ 18.x
• React Native CLI (or Expo for quick setup)
• Android Studio / Xcode (for testing)
• Google Cloud account (for API key)
• Git (to clone or fork the GitHub repo)

Project Structure Overview

Here’s what your folder structure will look like:

my-tts-app/
│
├── App.js
├── components/
│ └── TextToSpeech.js
├── utils/
│ └── googleTTS.js
├── assets/
├── package.json
└── .env

We’ll keep it modular, separating logic, UI, and API calls, so it’s easy to extend or plug into your project.

Install Required Dependencies

Run the following commands to install the dependencies:

        
            npm install react-native-dotenv
            npm install expo-av
            npm install axios
        
        

If you’re using bare React Native CLI (not Expo), use react-native-sound instead of expo-av.

Also, enable .env support by editing your babel.config.js:

        
           module.exports = {
              presets: ['babel-preset-expo'],
              plugins: [['module:react-native-dotenv']],
            };

• On button click, the text is sent to the Google Cloud TTS API.
• The API returns a base64-encoded MP3 audio.
• expo-av plays the audio in real-time.
• Fully cross-platform with just a few lines!
