Nuxt Whisper Demo

This is my parrot app that I built for fun. Say something and it will reply back.

About this demo

In this demo we use the front-end of a Nuxt 3 app to upload an audio file to a Nuxt API route.

The API route processes the file with the formidable library to parse the multipart file.

The file is then sent to OpenAI's Whisper API, which is an ASR (Automatic Speech Recognition) API.

Improvements

There are a few improvements I want to bring to the app. Below are a few of them.

Audio visualisation [status: research]

When the user speaks, we want to visualise the audio. We also want the visualisation for when the parrot speaks back.

Here is an article that I have found: A Guide To Audio Visualization With JavaScript And GSAP (Part 1)

General UI updates [status: research]

  • [] parrot icon, including the favicon
  • [] move the description out of the way, make it accessible via a button
  • [] make it visually appealing with an animated parrot

Make it a PWA

  • [] Make the app installable
  • [] Make it open offline
  • [] When offline, use the browser's SpeechSynthesis API

Configuration

You will need to create a .env file and set the OPENAI_KEY key to your own OpenAI key. This implies that you have an account at openai.com. Go to platform.openai.com/account/api-keys to create a new secret key.

Your .env file should look like this:

OPENAI_KEY=sk-dja9sd8jas9d8ajsd9asjda9djasd98sjd98ajd98sajdas9 # not a real key
