Hey Product Hunt! 👋 Thrilled to share The Thinking Speaker (TTS): an AI speaking and interview coach built for high-stakes moments! The Problem: Too many skilled candidates and students fail job interviews and vivas not because they don't know the material, but because thinking and speaking under pressure is a completely separate skill. Silent studying doesn't prepare you for spoken pressure. How TTS Solves It: We evolved TTS into a single platform covering three high-stakes arenas: 1. 💼 Interview Prep: Face a realistic AI interviewer that listens and responds naturally across 4 personas (from friendly to aggressive). Every session is recorded and scored so you can master tough follow-ups. 2. 🎓 Viva Prep: Upload PDFs and explain concepts out loud. TTS maps your verbal mastery across 'Recall, Explain, Apply,' and 'Analyze' so you see exactly where your understanding drops off. 3. 🎤 Speech Prep: A real-time voice-following teleprompter, AI Speech Writer, and 79+ historic speeches to sharpen your WPM, pauses, and filler words. 4. 🔒 Privacy-First Offline Mode: Run speech recognition entirely in your browser via Sherpa-ONNX and Vosk so your audio never leaves your device. You can start completely free. Give the aggressive interviewer persona a spin and let us know what you think in the comments! 👇
