Voice Interface Builder

This one gives you Web Speech API hooks for React that handle both speech recognition and text-to-speech. You get a useSpeechRecognition hook with continuous listening support and a useSpeechSynthesis hook with voice selection and playback controls. The command detection pattern is straightforward, matching phrases or regex patterns against transcripts. Good for adding voice search, dictation inputs, or hands-free navigation without reaching for external APIs. The code is client-side only and browser-dependent, so you'll want fallbacks. Works best for accessibility features or when keyboard and mouse aren't practical.
