Behind the Tech: The State-of-the-Art AI Avatars Powering JobInterview.live 🤖

We didn't just build a chatbot. We built a simulator.

Creating an AI that feels like a human interviewer requires a complex stack of cutting-edge technologies. Here is a peek under the hood of JobInterview.live.

🧠 The Brain: Large Language Models (LLMs)

We utilize a fine-tuned ensemble of models (including GPT-4o and Claude 3.5 Sonnet) specialized in:

• Context Retention: Remembering what you said 5 minutes ago.
• Behavioral Analysis: Understanding the intent behind your words.
• Socratic Method: Asking follow-up questions that make you think.

🗣️ The Voice: Low-Latency TTS

Traditional Text-to-Speech (TTS) sounds robotic. Ours uses Neural Audio Generation.

• Prosody: The AI pauses for effect, raises pitch for questions, and lowers it for serious statements.
• Speed: Sub-300ms latency. It feels like a real conversation, not a walkie-talkie exchange.

👁️ The Face: Real-Time Video Generation

This is our secret sauce.

• Lip Sync: Perfect synchronization between audio and visual.
• Micro-Expressions: The avatar blinks, nods, and tilts its head.
• Diversity: We offer avatars of different ethnicities, genders, and ages to simulate diverse hiring panels.
