The problem

Interview practice tools are text-based, so they never test the thing that fails under pressure: speaking.

What made it hard

Feedback has to arrive inside the call, which caps how long any model call can take.

Architecture

  1. 01Twilio handles the call and speech-to-text
  2. 02GPT-4 generates follow-up questions from the answer given
  3. 03MurfAI returns natural speech for the next prompt
  4. 04Postgres stores sessions and tracks progress across attempts

Outcomes

  • Scores each answer on speech rate, filler words, confidence and clarity
  • Tracks improvement across repeat sessions per user
  • JWT-authenticated REST API over Sequelize
