## Overview

This is a small text-to-speech web app: a user enters text, requests synthesis, and plays the returned audio. The React entry point renders the interface; the interface sends text to an Express endpoint, which calls Google Cloud Text-to-Speech and returns its response. The sampled sources support this core workflow, but do not establish further capabilities or deployment details.

Main entry points: [`text_speech/src/App.tsx`](https://github.com/tichzvidzayi/texttospeech/blob/main/text_speech/src/App.tsx) (Text-to-speech UI), [`text_speech/src/server/server.ts`](https://github.com/tichzvidzayi/texttospeech/blob/main/text_speech/src/server/server.ts) (Synthesis endpoint), [`text_speech/src/index.js`](https://github.com/tichzvidzayi/texttospeech/blob/main/text_speech/src/index.js) (React entry)
