From 63a333bba3d136cb05ea7ffd2b87c469877c1cdc Mon Sep 17 00:00:00 2001 From: Andrei Date: Wed, 1 Oct 2025 20:24:43 +0000 Subject: [PATCH] Add voice input UI components for hands-free tracking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented complete voice input user interface: **Voice Recording Hook (useVoiceInput):** - Browser Web Speech API integration - Real-time speech recognition - Continuous and interim results - 10-second auto-timeout - Error handling for permissions, network, audio issues - Graceful fallback for unsupported browsers **Voice Input Button Component:** - Modal dialog with microphone button - Animated pulsing microphone when recording - Real-time transcript display - Automatic intent classification on completion - Structured data visualization - Example commands for user guidance - Success/error feedback with MUI Alerts - Confidence level indicators **Floating Action Button:** - Always-visible FAB in bottom-right corner - Quick access from any page - Auto-navigation to appropriate tracking page - Snackbar feedback messages - Mobile-optimized positioning (thumb zone) **Integration with Tracking Pages:** - Voice button in feeding page header - Auto-fills form fields from voice commands - Seamless voice-to-form workflow - Example: "Fed baby 120ml" → fills bottle type & amount **Features:** - ✅ Browser speech recognition (Chrome, Edge, Safari) - ✅ Real-time transcription display - ✅ Automatic intent classification - ✅ Auto-fill tracking forms - ✅ Visual feedback (animations, colors) - ✅ Error handling & user guidance - ✅ Mobile-optimized design - ✅ Accessibility support **User Flow:** 1. Click microphone button (floating or in-page) 2. Speak command: "Fed baby 120 ml" 3. See real-time transcript 4. Auto-classification shows intent & data 5. Click "Use Command" 6. Form auto-fills or activity created **Browser Support:** - Chrome ✅ - Edge ✅ - Safari ✅ - Firefox ❌ (Web Speech API not supported) **Files Created:** - hooks/useVoiceInput.ts - Speech recognition hook - components/voice/VoiceInputButton.tsx - Modal input component - components/voice/VoiceFloatingButton.tsx - FAB for quick access - app/layout.tsx - Added floating button globally - app/track/feeding/page.tsx - Added voice button to header Voice input is now accessible from anywhere in the app, providing true hands-free tracking for parents. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- maternal-web/app/layout.tsx | 2 + maternal-web/app/track/feeding/page.tsx | 25 +- .../components/voice/VoiceFloatingButton.tsx | 112 +++++++ .../components/voice/VoiceInputButton.tsx | 298 ++++++++++++++++++ maternal-web/hooks/useVoiceInput.ts | 182 +++++++++++ 5 files changed, 618 insertions(+), 1 deletion(-) create mode 100644 maternal-web/components/voice/VoiceFloatingButton.tsx create mode 100644 maternal-web/components/voice/VoiceInputButton.tsx create mode 100644 maternal-web/hooks/useVoiceInput.ts diff --git a/maternal-web/app/layout.tsx b/maternal-web/app/layout.tsx index af27e06..b47aac1 100644 --- a/maternal-web/app/layout.tsx +++ b/maternal-web/app/layout.tsx @@ -3,6 +3,7 @@ import { Inter } from 'next/font/google';
