+# Language Learning Companion (with PowerMem)
+
+A voice AI language tutor enhanced with [PowerMem](https://github.com/oceanbase/powermem/) for persistent memory of vocabulary, learning progress, and personalized lessons.
+
+## Overview
+
+This is a **memory-enabled voice AI use case** for the Oceanbase Developer Challenge 2026. The Language Learning Companion uses TEN Framework with PowerMem to provide personalized language education that:
+
+- **Remembers vocabulary words** learned across sessions
+- **Tracks grammar concepts** covered in each lesson
+- **Provides personalized practice** based on the learner's level
+- **Reviews previously learned material** to reinforce memory
+- **Adapts to learning style** through long-term context accumulation
+
+## Use Case: Personalized Language Tutor
+
+### Memory Design
+
+The tutor uses PowerMem to store and retrieve different types of learning data:
+
+| Memory Type | Content | Retrieval Strategy |
+|-------------|---------|-------------------|
+| **Vocabulary** | Words, phrases, translations | Semantic search by topic/language |
+| **Grammar** | Rules, examples, explanations | Context-aware retrieval by topic |
+| **Progress** | Lesson history, quiz scores | Timeline-based review |
+| **Preferences** | Learning style, native language | User profile retrieval |
+
+### How Memory Works
+
+1. **Learning New Words**: When a user learns a new vocabulary word, it's stored with metadata (language, level, topic)
+2. **Grammar Sessions**: Each grammar lesson is summarized and stored for future reference
+3. **Personalized Review**: Before each session, relevant memories are retrieved to provide context
+4. **Progress Tracking**: Quiz results and practice scores are saved to track improvement
+
+### Example Conversation Flow
+
+```
+User: Teach me the Spanish word for "apple"
+Tutor: "Apple" in Spanish is "manzana". Let me remember this for you.
+       Now, can you use "manzana" in a sentence?
+
+User: I eat an manzana
+Tutor: Good try! The correct sentence is "Como una manzana" or "Me como una manzana".
+       Remember: "manzana" is feminine (la manzana).
+```
+
+## PowerMem Configuration
+
+Set the environment variables in `.env` file:
+
+```bash
+# Database (PowerMem/Oceanbase)
+DATABASE_PROVIDER=oceanbase
+OCEANBASE_HOST=127.0.0.1
+OCEANBASE_PORT=2881
+OCEANBASE_USER=root
+OCEANBASE_PASSWORD=password
+OCEANBASE_DATABASE=oceanbase
+OCEANBASE_COLLECTION=language_tutor_memories
+
+# LLM Provider (for PowerMem)
+LLM_PROVIDER=qwen
+LLM_API_KEY=your_qwen_api_key
+LLM_MODEL=qwen-plus
+
+# Embedding Provider (for PowerMem)
+EMBEDDING_PROVIDER=qwen
+EMBEDDING_API_KEY=your_qwen_api_key
+EMBEDDING_MODEL=text-embedding-v4
+EMBEDDING_DIMS=1536
+
+# Voice Services
+AGORA_APP_ID=your_agora_app_id
+DEEPGRAM_API_KEY=your_deepgram_api_key
+ELEVENLABS_TTS_KEY=your_elevenlabs_key
+
+# LLM for Chat
+OPENAI_API_KEY=your_openai_api_key
+OPENAI_MODEL=gpt-4
+```
+
+## Prerequisites
+
+### Required Services
+
+1. **Oceanbase Database** (for PowerMem)
+   ```bash
+   docker run -d \
+     --name seekdb \
+     -p 2881:2881 \
+     -p 2886:2886 \
+     -v ./data:/var/lib/oceanbase \
+     -e SEEKDB_DATABASE=powermem \
+     -e ROOT_PASSWORD=password \
+     oceanbase/seekdb:latest
+   ```
+
+2. **Agora Account** - Get credentials from [Agora Console](https://console.agora.io/)
+   - `AGORA_APP_ID` (required)
+
+3. **API Keys**:
+   - Deepgram for ASR (`DEEPGRAM_API_KEY`)
+   - ElevenLabs for TTS (`ELEVENLABS_TTS_KEY`)
+   - OpenAI for LLM (`OPENAI_API_KEY`)
+   - Qwen for PowerMem embeddings (`LLM_API_KEY`, `EMBEDDING_API_KEY`)
+
+## Quick Start
+
+1. **Install dependencies:**
+   ```bash
+   task install
+   ```
+
+2. **Run the Language Tutor:**
+   ```bash
+   task run
+   ```
+
+3. **Access the application:**
+   - Frontend: http://localhost:3000
+   - API Server: http://localhost:8080
+   - TMAN Designer: http://localhost:49483
+

+```
+
+## Memory Flow
+
+1. **Input**: User speaks via Agora RTC
+2. **STT**: Audio converted to text via Deepgram
+3. **Processing**: Main controller extracts learning content
+4. **Memory Retrieval**: PowerMem searches for relevant memories
+5. **LLM Generation**: GPT-4 generates contextual response
+6. **Memory Storage**: New learning content saved to PowerMem
+7. **Output**: Response spoken via ElevenLabs TTS
+
+## Customization
+
+### Adjust Memory Settings
+
+Modify `tenapp/property.json`:
+
+```json
+"memory_save_interval_turns": 3,    // Save every N turns
+"memory_idle_timeout_seconds": 60.0, // Session timeout
+"max_memory_length": 20              // Max conversation history
+```
+
+### Customize Tutor Persona
+
+Update the `custom_system_prompt` in `property.json`:
+
+```json
+"custom_system_prompt": "You are a Spanish tutor..."
+```

+  language-tutor-app
+```
+
+## Troubleshooting
+
+- **Memory not persisting**: Check Oceanbase connection and `OCEANBASE_*` variables
+- **Audio issues**: Verify `AGORA_APP_ID`, `DEEPGRAM_API_KEY`, `ELEVENLABS_TTS_KEY`
+- **LLM errors**: Confirm `OPENAI_API_KEY` is valid
+- **PowerMem errors**: Ensure `LLM_API_KEY` and `EMBEDDING_API_KEY` are set

Providing personalized practice based on their level\n4. Reviewing previously learned material to reinforce memory\n\nWhen a user learns a new word, acknowledge it and ask them to practice using it in a sentence.\nWhen they make mistakes, gently correct them and explain the grammar rule.\nBefore each lesson, briefly review what was covered in previous sessions if available in memory.\n\nYour goal is to make language learning engaging, personalized, and effective through consistent memory of the user's progress."
