Adding Text to Speech to React

Text-to-speech is quickly becoming a must-have feature on the modern web. Whether you are building an accessibility-first app, a reading companion, or just want to give your users another way to consume content, adding voice to your React project is easier than you might think.

This guide walks through how browser-based speech works, the trade-offs of different approaches, and how to integrate TTS2Go into your React app step by step.

Every modern browser ships with the Web Speech API. You can call window.speechSynthesis.speak() with a SpeechSynthesisUtterance and hear text read aloud without installing anything or calling an external service.

Key characteristics:

• Free and requires no API key
• Runs entirely on the client
• No backend or external service required

Main drawback: quality

• Voices often sound robotic
• Voice quality and selection vary between operating systems and browsers
• Limited set of voices and languages
• The same text can sound completely different across devices

This inconsistency makes it hard to deliver a predictable, high-quality listening experience to all users.

AI-powered text-to-speech has changed the game. Neural voice models produce audio that sounds remarkably human, with natural intonation, pacing, and emotion.

Benefits of AI TTS:

• Human-like, natural-sounding speech
• Better intonation, rhythm, and emphasis
• Dozens of languages and hundreds of voices

Trade-off:

Generating this audio requires an API call to a remote service. That introduces an architectural question: when and where do you generate the audio?

One approach is to generate all your audio ahead of time and serve it as static files.

Upsides:

• Very fast playback: audio is already on a CDN
• Consistent quality for every listener

Downsides:

• Cost: you pay to generate audio for every piece of content, even if nobody listens
• Requires knowing all content in advance
• Not suitable for dynamic or user-generated text
• Any content change triggers a new generation pipeline
• Storage costs grow linearly with your content library

This model works best for fixed, high-value content where you can justify pre-generation costs.

The alternative is to generate audio only when a user actually requests it.

Upsides:

• Far cheaper: you only pay for content people actually listen to
• Works seamlessly with dynamic and user-generated content

TTS2Go takes a hybrid approach that combines browser TTS with AI voices.

Default behavior:

• The SDK uses the browser's built-in speech synthesis as the default
• Every user gets text-to-speech out of the box
• Zero cost and zero configuration for you

Upgrade path:

• When a user signs up for a TTS2Go account, the SDK seamlessly upgrades them to high-quality AI-generated voices
• No API keys are shipped in your frontend code
• Authentication is handled securely via the user's own TTS2Go account

What you get:

• Free browser TTS as a baseline for everyone
• Premium AI voices for users who want them
• No need to manage keys, proxies, or custom infrastructure

Install the TTS2Go React package in your project directory:

Wrap your application with the TTS2GoProvider at the root of your component tree. This sets up the audio context and manages voice connections for all child components.

```tsx

import { StrictMode } from "react";

import { createRoot } from "react-dom/client";

import { TTS2GoProvider } from "@tts2go/react";

import App from "./App";

const config = {

apiKey: "YOURAPIKEY",

projectId: "YOURPROJECTID",

Use the useTTS hook in any component to get play, pause, and stop controls. For a quick drop-in UI, you can also use the pre-built TTSButton.

```tsx

import { TTSButton, useTTS } from "@tts2go/react";

const VOICE_ID = "your-voice-id";

export default function Article({ text }: { text: string }) {

const { status, play, stop, pause } = useTTS(text, VOICE_ID);

return (

Once you have the basics working, you can extend your integration with:

• Voice selection: let users choose from different voices and languages
• SSML support: fine-tune pronunciation, pauses, emphasis, and prosody
• Highlight API: sync on-screen text with spoken words for a read-along experience
