**Everyone-Can-Use-English is a full-stack web application that combines AI chat, speech synthesis, pronunciation assessment, and multimedia lessons to create an interactive English practice environment.**

This open-source project by ZuodaoTech provides learners with conversation practice through large language models, automated speech feedback, and comprehensive progress tracking. Below is a detailed breakdown of its core capabilities based on the source code architecture.

## AI-Powered Conversation & Chat

The platform enables **context-aware dialogue practice** with LLM-generated responses that simulate real conversations.

The chat system is backed by a dedicated database schema defined in [`enjoy/src/main/db/migrations/1722039161323-create-chats.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/src/main/db/migrations/1722039161323-create-chats.js):

```javascript
// Start a new chat session (backend)
import { db } from "./src/main/db";
await db.chat.create({ userId, title: "Practice Conversation" });

```

Conversations are persisted and can be resumed across sessions, allowing learners to build ongoing practice routines.

## Speech Synthesis & Audio Playback

Everyone-Can-Use-English generates **spoken audio for prompts and AI responses**, supporting auditory learning styles.

Audio assets are managed through [`enjoy/src/main/db/migrations/1703902823343-create-audio.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/src/main/db/migrations/1703902823343-create-audio.js). The front-end build pipeline in [`enjoy/vite.main.config.ts`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/vite.main.config.ts) handles audio file serving and optimization.

## Pronunciation Assessment

A standout feature is the **automated pronunciation feedback system**. Learners record their voice and receive accuracy scoring without human intervention.

The assessment infrastructure is established in [`enjoy/src/main/db/migrations/1703902870618-create-pronunciation-assessment.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/src/main/db/migrations/1703902870618-create-pronunciation-assessment.js):

```javascript
// Record a user's voice and trigger pronunciation assessment
import { db } from "./src/main/db";
const recording = await db.recording.create({ userId, audioBlob });
await db.pronunciationAssessment.create({ recordingId: recording.id });

```

This creates a closed loop: speak, assess, and improve.

## Voice Recording & Transcription

The platform supports **spoken answer capture with automatic transcription**, bridging speech and text for comprehensive skill development.

Two migrations handle this pipeline:
- [`enjoy/src/main/db/migrations/1703902843307-create-recording.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/src/main/db/migrations/1703902843307-create-recording.js) — stores raw audio
- [`enjoy/src/main/db/migrations/1704030985573-create-transcription.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/src/main/db/migrations/1704030985573-create-transcription.js) — persists transcribed text

## Video-Based Lessons

Multimedia content delivery includes **embedded video materials for listening practice**, managed through [`enjoy/src/main/db/migrations/1703902826529-create-video.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/src/main/db/migrations/1703902826529-create-video.js). Videos are integrated alongside interactive elements rather than treated as static resources.

## User Settings & Progress Tracking

Personalization is enabled through [`enjoy/src/main/db/migrations/1725411577564-create-user-setting.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/src/main/db/migrations/1725411577564-create-user-setting.js), which stores:
- Language preferences
- Learning history
- Custom configurations

This supports long-term progress monitoring across multiple learning sessions.

## Multi-Modal Front-End Interface

The user interface unifies text chat, audio playback, and video playback through a **Tailwind CSS + React + Vite stack**:

- [`enjoy/tailwind.config.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/tailwind.config.js) — utility-first styling configuration
- [`enjoy/vite.base.config.ts`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/vite.base.config.ts) and [`enjoy/vite.renderer.config.ts`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/enjoy/vite.renderer.config.ts) — build tooling for main and renderer processes

```typescript
// Vite config enabling Tailwind and React for the front-end
import { defineConfig } from "vite";
export default defineConfig({
  plugins: [require("@tailwindcss/vite")()],
});

```

## Bundled Learning Resources

The repository includes **exportable markdown-based lessons** such as the English Voice Tutorial (`new-edition-drafts/英文语音简明教程.md`). These materials can be served directly or converted for other formats.

## Serverless Deployment Architecture

The back-end runs on **Cloudflare Workers for low-latency AI interactions**:
- [`entry/index.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/entry/index.js) — request routing and API handling
- [`entry/wrangler.toml`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/entry/wrangler.toml) — deployment configuration

This serverless design reduces infrastructure costs and improves global accessibility.

## Frequently Asked Questions

### How does the pronunciation assessment feature work?

The pronunciation assessment feature stores user recordings in a dedicated table via [`create-recording.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/create-recording.js), then creates linked assessment records through [`create-pronunciation-assessment.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/create-pronunciation-assessment.js). The actual scoring logic likely integrates with external speech recognition APIs, with results persisted for progress tracking.

### Can I run Everyone-Can-Use-English without Cloudflare Workers?

While the primary deployment target is Cloudflare Workers ([`entry/index.js`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/entry/index.js) and [`entry/wrangler.toml`](https://github.com/ZuodaoTech/everyone-can-use-english/blob/main/entry/wrangler.toml)), the database migrations and core logic in `enjoy/src/main/db/` are framework-agnostic. Adapting to other serverless platforms or traditional servers would require replacing the worker-specific routing layer.

### What database does Everyone-Can-Use-English use?

The migration files indicate a **SQL-based relational database** accessed through an ORM layer. The specific database engine isn't enforced by the migrations themselves—SQLite, PostgreSQL, or MySQL could all satisfy the schema requirements depending on deployment configuration.

### Is the learning content customizable?

Yes. The `new-edition-drafts/` directory demonstrates that lessons are stored as **markdown files**, making them editable without code changes. The video and audio systems also support dynamic content injection through their respective database tables.
