🔊 react-voice-search-widget

A plug-and-play React component that lets users search either by typing or using voice input (speech-to-text). Built for reusability, flexibility, and quick integration into any modern React application.

✨ Features

• 🎤 Voice Input Support
  Capture audio from the microphone and transcribe it using a backend speech-to-text service (e.g., Vosk).

• ⌨️ Text Input Support
  Supports both voice and manual text input in the same field.

• 🔍 Real-Time Search
  Automatically queries a backend search API as you speak or type (with debounce).

• 🎯 Keyword Highlighting
  Matched words are highlighted in the search results and transcript text.

• ⚛️ Modular and Reusable
  Packaged as a standalone React component that can be embedded in any React app.

• 💬 Error Handling
  Includes fallback for unsupported browsers and clear messages when audio isn't captured or no results are found.

📦 Installation

Install the component via NPM:

npm install react-voice-search-widget
# or
yarn add react-voice-search-widget

🚀 Usage

import React from 'react';
import VoiceInput from 'react-voice-search-widget';

function App() {
  return (
    <div style={{ maxWidth: 800, margin: '0 auto', padding: '1rem' }}>
      <VoiceInput />
    </div>
  );
}

export default App;

🧱 Component Overview

VoiceInput.tsx

The main component that handles:

• Microphone access
• Recording and sending audio to the backend
• Typing + voice input management
• Displaying real-time search results

SearchResults.tsx

Displays the result list and highlights matched keywords.

UnsupportedBrowserFallback.tsx

Renders a fallback message if the browser doesn't support MediaRecorder or microphone access.

🛠️ Backend API Expectations

Your backend should expose two endpoints:

/api/transcribe (POST)

• Accepts an audio file (multipart/form-data) and returns a JSON { text: "transcribed text" }.

/search?q=query (GET)

• Accepts a search query and returns results in the following format:

{
  "results": [
    {
      "id": "1",
      "name": "<highlighted text>",
      "category": "<highlighted category>",
      "matchedWords": ["keyword1", "keyword2"]
    }
  ]
}

🎨 Styling

Tailwind CSS is used for styling. If your host app uses Tailwind, styles will integrate seamlessly. Otherwise, you may want to adjust or override styles accordingly.

📌 Customization (Coming Soon)

Planned for future versions:

• Props to override API endpoints
• Custom result renderers
• Adjustable debounce delay
• Theming via CSS variables
