Featured Challenge:
#188 — Voice Chatbot

In this coding challenge, I build a conversational voice chatbot entirely in the browser with p5.js. I combine three pieces: speech-to-text with OpenAI's Whisper model, text-to-speech with Kokoro TTS, and a "brain" for the bot. I also explore the transformers.js pipeline API and the Web Audio API. For the bot's brain, I start with a simple ELIZA-style therapist, then incorporate a RiveScript number-guessing game, and finally a local LLM.

Let's make ASCII art in p5.js together! In this video, I demonstrate a variety of techniques for translating the pixels of an image into text and finish with rendering video as text ASCII characters in a DOM.

In this video I explore the wonders of the copy() function in the creative coding platform Processing, simulating slitscan photography and bending time itself! This video is thanks to Tim Rodenbröker’s generous donation to The Processing Foundation!
