Undoing the Chatbot
summary
Built a working chatbot that runs largely in the browser using SpeechRecognition/SpeechSynthesis Web APIs and a tiny Express backend, implemented in plain JavaScript + Express, with a Naive‑Bayes style classifier and the sentiment module for polarity scoring. It works best in Chrome, handles simple intents from a small JSON training set, exposes biases (no Haitian Creole support, default female voice norms), and shows where browser support and opaque ML make failures and misclassification likely.
