PLAN MY TRIP v1.0 — Architecture Polish & Voice Companion Milestone

We're excited to post an update on how PLAN MY TRIP has evolved over the course of the hackathon! We’ve transitioned from initial planning concepts to a fully functional, multimodal travel companion.

Key Improvements & Newly Integrated Features:

  1. Hands-Free Alexa+ Voice Companion:

    • Integrated continuous speech recognition with natural wake-word detection ("Hello Alexa").
    • Added speech sanitization to turn dense itineraries and technical status logs into crisp, conversational 1–2 sentence voice replies (<160 characters).
    • Enabled audio barge-in interruption so users can seamlessly speak mid-response.

  2. Autonomous Disruption Recovery & MCP Tooling:

    • Implemented Model Context Protocol (MCP) tools for real-time schedule tracking (assess_disruption, prepare_recovery_action).
    • The agent automatically detects transit delays, evaluates route alternatives, and prepares instant recovery options.

  3. Strict Human-in-the-Loop Safety Gate:

    • Autonomous actions (ticket cancellations, bus switches, hotel notices) are never blindly executed.
    • Every critical adjustment generates an interactive review card requiring explicit user confirmation (Approve & Confirm vs. Reject).

  4. Production Stability & Persistence:

    • Switched backend storage to SQLite with WAL (Write-Ahead Logging) mode for concurrent access and persistent state across server restarts.
    • Full end-to-end testing completed across voice input, live trip switching, and fallback safety behaviors.

What's Next on the Roadmap:

  • Multi-lingual Indian regional voice recognition (Hindi, Telugu, Kannada, Tamil).
  • Direct real-time webhook feeds with live airline (DGCA/FlightRadar) and railway (IRCTC) APIs.
  • Collaborative trip editing for group travels with shared voice permissions.
