## Overview

WIA-PET-010 is a comprehensive standard for translating animal communication into human-understandable formats using artificial intelligence and machine learning. This standard enables deeper understanding and stronger bonds between humans and their companion animals.

### Key Features

- 🎤 **Vocalization Analysis** - Advanced audio processing for barks, meows, chirps, and more
- 👁️ **Body Language Recognition** - Computer vision for posture, tail position, facial expressions
- 🧠 **Emotion Detection** - Multi-dimensional emotion analysis with 10+ emotion categories
- 🌍 **Multi-Language Support** - Translations in 50+ human languages
- 📊 **Context-Aware** - Temporal, environmental, and historical context integration
- ⚡ **Real-Time** - Sub-second latency for live translation
- 🔒 **Privacy-First** - Local processing option with end-to-end encryption

### Supported Species

- 🐕 Dogs (all breeds)
- 🐱 Cats (domestic and specific breeds)
- 🦜 Birds (parrots, parakeets, songbirds)
- 🐰 Rabbits & Guinea Pigs
- 🐹 Hamsters & Small Rodents

## Quick Start

### Installation

### 💻 API Documentation

#### TypeScript SDK

```typescript
import { PetTranslator, TranslationEvent, Species } from '@wia/pet-translator';

// One-time translation
const result = await translator.translate({
  petProfile: {
    petId: 'max',
    species: Species.Dog,
    breed: 'Golden Retriever'
  },

    audio: {
      sampleRate: 44100,
      channels: 1,
      bitDepth: 16,
      duration: 2000,
      format: 'wav',
      encoding: 'base64',
      data: audioBase64
    }
  }
});

console.log(result.translations.en);
// "I hear something unusual outside. Should we check it out?"

// Get emotion timeline
const timeline = await translator.getEmotionTimeline({
  petId: 'max',
  startDate: new Date('2025-01-15'),
  endDate: new Date('2025-01-16')
});

console.log(timeline.summary.averageValence); // 0.65
console.log(timeline.summary.mostCommonEmotion); // "content"
```
