🎙️ VoxAI

Voice calls that don’t just talk — they act.

VoxAI is a generalized AI-powered voice agent platform for handling inbound and outbound calls with real-time understanding, contextual memory, and automated follow-up actions like sending emails and documents.

🚨 Problem

Voice communication is still one of the least automated channels for organizations and government agencies.

Existing IVR systems and voice bots:

• Are rigid and turn-based
• Fail to handle interruptions naturally
• Stop at answering questions
• Require humans for follow-ups (emails, documents, confirmations)
• Rarely support intelligent outbound calls
• Are tightly coupled to a single domain

As a result, voice workflows remain manual, slow, and difficult to scale.

---

💡 Solution

VoxAI treats voice as a workflow trigger, not just an interface.

It provides:

• A reusable voice intelligence layer
• Pluggable knowledge sources
• Configurable agent profiles
• Built-in action execution (email, PDF, follow-ups)

The same platform can be adapted for governments, enterprises, education, or support systems by changing configuration — not core logic.

✨ Key Capabilities

• Real-time, interruptible conversations
  Handles overlapping speech and mid-sentence corrections.

• Inbound & outbound calls
  Responds to incoming calls and initiates outbound calls programmatically.

• Automated follow-up actions
  Generates PDFs and sends emails directly from call context.

• Contextual memory
  Maintains state across long or multi-step conversations.

• Multi-agent architecture
  Multiple agent profiles with different knowledge and tools.

• Pluggable knowledge layer
  Domain knowledge is injected, not hardcoded.
