# Voice Agent SDK

> Infrastructure SDK for building real-time AI voice agents with STT, TTS, and LLM capabilities for easy custom voice agent development.

## Overview

The Voice Agent SDK is a comprehensive infrastructure solution that enables businesses to build custom real-time AI voice agents. Similar to the Agora Conversation SDK, our platform provides all the essential components for voice agent development including Speech-to-Text (STT), Text-to-Speech (TTS), and Large Language Model (LLM) integration with easy-to-use configuration options.

## Architecture

The Voice Agent SDK follows a modular architecture that provides:

1. **Core Communication Layer**: Handles real-time voice streaming and media processing
2. **AI Processing Layer**: Manages STT, TTS, and LLM integration
3. **Configuration Layer**: Simplified API for customizing agent behavior
4. **Integration Layer**: Connectors for CRMs, databases, and business systems

## Getting Started

### Installation

```bash theme={null}
npm install @voxeme/voice-agent-sdk
```

### Basic Implementation

```javascript theme={null}
import { VoiceAgent } from '@voxeme/voice-agent-sdk';

const agent = new VoiceAgent({
  stt: {
    provider: 'deepgram', // or 'assemblyai', 'google', etc.
    config: {
      // STT configuration
    }
  },
  tts: {
    provider: 'elevenlabs', // or 'google', 'amazon', etc.
    config: {
      voice: 'default',
      // TTS configuration
    }
  },
  llm: {
    provider: 'openai', // or 'anthropic', 'cohere', etc.
    config: {
      model: 'gpt-4',
      // LLM configuration
    }
  }
});

// Start the agent
agent.start();
```

## Core Components

### Speech-to-Text (STT)

Support for multiple STT providers:

* Deepgram (recommended for accuracy)
* AssemblyAI (good balance of quality and cost)
* Google Cloud Speech-to-Text
* Amazon Transcribe
* Azure Speech Services

### Text-to-Speech (TTS)

Multiple TTS options with natural voices:

* ElevenLabs (highest quality)
* Google Cloud Text-to-Speech
* Amazon Polly
* Azure Text-to-Speech
* Custom neural voices

### Language Model Integration

Flexible LLM integration:

* OpenAI GPT models
* Anthropic Claude
* Cohere Command
* Custom fine-tuned models
* On-premises LLMs

## Configuration Options

### Agent Personality

```javascript theme={null}
const agent = new VoiceAgent({
  personality: {
    tone: 'friendly', // or 'professional', 'casual', 'enthusiastic'
    speakingStyle: 'conversational', // or 'formal', 'direct'
    responseLength: 'concise', // or 'detailed'
    language: 'en-US'
  }
});
```

### Conversation Flow

```javascript theme={null}
const agent = new VoiceAgent({
  conversation: {
    greeting: 'Hello! How can I assist you today?',
    timeout: 30, // seconds before timeout prompt
    maxTurns: 20, // maximum conversation turns
    interruptionHandling: true
  }
});
```

## Advanced Features

### Knowledge Base Integration

```javascript theme={null}
const agent = new VoiceAgent({
  knowledgeBase: {
    type: 'vector', // or 'graph', 'document'
    source: 'your-knowledge-base-id',
    retrievalMethod: 'similarity'
  }
});
```

### Tool Calling

```javascript theme={null}
const agent = new VoiceAgent({
  tools: [
    {
      name: 'check_order_status',
      description: 'Check the status of a customer order',
      parameters: {
        orderId: { type: 'string', required: true }
      },
      handler: async (params) => {
        // Your implementation
        return orderStatus;
      }
    }
  ]
});
```
