Build Your First AI Voice Chatbot from Scratch with OpenAI (Whisper, GPT-4, TTS), Flask & ReactJS

AI Voice Assistants will be huge in 2024.

I’m jumping on the bandwagon of AI Voice Chatbots.

They will be huge for many reasons:

• Speaking is easier than typing.
• Listening is easier than reading.
• People are moving from typing to speaking.
• Typing on mobile devices is time-consuming.

For smartphones, voice assistants will be the default choice!

So I decided to build my first full-stack application to be used purely with voice (check out the repo & the demo). To build it, I chose the package of OpenAI models:

1. Whisper (speech-to-text). Used to transcribe my voice into text.
2. GPT-4 or GPT-3.5(Large Language Models). Responses to the transcript from Whisper.
3. TTS (text-to-speech). It synthesizes the GPT-4 response into audio, such as mp3.

And because my app is working now, I’m here to teach you how you can do the same. We’ll use the following technologies:

1. Flask for the back-end part.
2. ReactJS for the front-end part.
