Talking AI

Talking AI is a simple Node.js application that allows you to upload an MP3 file, convert the speech to text using OpenAI's Whisper API, generate an intelligent answer using OpenAI GPT, and finally convert the generated answer back into speech for playback. This app is designed with a basic front-end and demonstrates a clear chain of AI-based interactions,starting from voice, moving through natural language understanding, and returning to voice.

Purpose

The aim of this project is to demonstrate how voice-driven AI pipelines can be built using modern tools like Whisper and GPT. It helps developers explore how human-like interaction can be achieved with audio input and output. This can be extended for use cases such as voice assistants, learning tools, customer support bots, and more,especially for Turkish or multilingual audiences.
