Build a Voice-Controlled Todo List App (Web Speech API)

Create a futuristic todo app where users can add tasks, mark them complete, or delete them using just their voice — blending modern speech recognition with intuitive productivity features.

Why Build a Voice-Controlled Todo App?

Hands-free productivity is becoming a major trend. Building this project teaches you Web Speech API integration, speech-to-text processing, voice command parsing, and dynamic task management — skills perfect for AI-based and accessibility-focused apps.

Core Features of the Voice Todo App

Users speak commands like 'Add task Buy groceries' or 'Complete task two'. The app processes speech input, understands user intents, and updates the todo list dynamically — making task management fast, fun, and accessible.

Key Features to Implement

Speech Recognition for Commands

Use Web Speech API to listen to user voice input and extract commands like add, delete, or complete tasks.

Task Management (CRUD)

Support creating, updating, completing, and deleting todo tasks dynamically based on user voice commands.

Voice Feedback (Optional)

Respond back to users with voice (SpeechSynthesis) to confirm actions like 'Task added successfully!'

Manual Control Fallback

Allow users to manually add/edit tasks if they prefer typing, making the app usable even without microphone access.

How the Voice-Controlled Todo App Works

Users click a 'Start Listening' button, speak natural commands like 'Add task', 'Complete task', 'Delete task'. The Web Speech API captures their speech, your app parses intents, and dynamically updates the todo list in real time.

  • Users press the microphone button and speak commands naturally (e.g., 'Add task Finish homework').
  • Web Speech API captures voice input and converts it to text automatically inside the browser.
  • Your app parses text for intent (add, complete, delete) and updates the todo list instantly.
  • Optional: Speak back confirmations like 'Added task successfully!' using SpeechSynthesis API.
  • Fallback manual input ensures accessibility even when voice isn't available or preferred.
Recommended Technology Stack

Frontend Framework

React.js + Tailwind CSS for dynamic todo list UI, microphone control, and task animations

Voice Recognition

Web Speech API (SpeechRecognition and SpeechSynthesis) for voice commands and feedback

Optional Enhancements

IndexedDB/localStorage for saving tasks offline, mobile responsiveness for native-like experience

Optional Bonus

Integrate NLP libraries like compromise.js for smarter intent detection from speech text

Step-by-Step Build Guide

1. Build Basic Todo List (CRUD)

Set up React components for adding, completing, deleting, and listing todo tasks manually first.

2. Integrate Web Speech API for Listening

Add a microphone button that starts listening for voice input and converts it into text live.

3. Parse Commands from Text

Analyze spoken text to detect actions like 'add', 'complete', or 'delete' tasks and act accordingly.

4. Add Voice Feedback (Optional)

Use SpeechSynthesis API to audibly confirm actions like 'Task completed' or 'Task deleted'.

5. Polish UX, Optimize for Mobile, and Deploy

Design mobile-friendly UI, add accessibility features, test speech recognition quality, and deploy live on Vercel/Netlify.
