📋 Project Description

The Sambanova Voice AI Productivity System is an advanced AI-powered voice assistant that integrates Redis for session management and caching, Composio for external tool orchestration, and real-time audio processing to provide seamless productivity management through natural voice interactions. The system features WebRTC voice communication, Redis-based session persistence, Composio tool integrations (Slack, GitHub, Gmail, Notion, Jira), and comprehensive audio stream processing with WebM format support for enterprise-grade voice AI applications.

Redis Implementation Details

# Session Management  
session_data = {  
    'user_id': 'user-123',  
    'audio_buffer': 'base64_encoded_audio',  
    'created_at': timestamp,  
    'expires_at': ttl,  
    'activity_log': []  
}  
  
# Pub/Sub Notifications  
redis_client.publish('team_updates', {  
    'user_id': user_id,  
    'action': 'todo_created',  
    'timestamp': now()  
})  

Composio Integration Details

# Tool Loading with Fallback  
if hasattr(toolset, 'get_tools'):  
    tools = toolset.get_tools(apps=["slack"])  
elif hasattr(toolset, 'get_actions'):  
    tools = toolset.get_actions(apps=["slack"])  
  
# OAuth2 Authentication  
composio_client = ComposioToolSet(api_key=COMPOSIO_API_KEY)  
slack_tools = composio_client.get_tools(apps=["slack"])
