Web Speech API for TTS

A native browser interface that converts text into synthesized speech using local system voices without external plugins.

Control speech synthesis through the window.speechSynthesis controller and the SpeechSynthesisUtterance object. This API allows you to programmatically adjust pitch (0 to 2), rate (0.1 to 10), and volume (0 to 1) while selecting from a list of available system voices like Google US English or Microsoft David. It provides a low-latency solution for accessibility and interactive UI across major platforms (Chrome 33+, Safari 7+, and Edge). Since processing happens on the client side, it reduces server load and maintains user privacy during text-to-audio conversion.
