speak.js is a port of the eSpeak C++ speech synthesizer to JavaScript via Emscripten, enabling text-to-speech in the browser using only JavaScript and HTML5. It generates WAV audio from text in a web worker and plays it through an HTML Audio element.

Use cases

• add text-to-speech to a web page without a server
• convert text to spoken audio in the browser
• make a website read content aloud for accessibility
• generate WAV speech audio client-side in JavaScript
• support multiple spoken languages in a web app
• build a browser-based talking application

When to choose

• you need client-side TTS with no server dependency
• you want a lightweight, self-contained speech synthesizer for the web
• you need multilingual eSpeak voices in JavaScript

When to avoid

• you need high-quality, natural-sounding modern neural voices
• you need a maintained library with active updates
• you need TTS outside the browser or on mobile native apps
