## AI Voice Feedback Tool Technical Documentation
### Overview
The AI Voice Feedback Tool is designed to convert written feedback into natural-sounding speech, enhancing accessibility and providing immediate auditory reinforcement. This tool consists of a FastAPI backend for processing requests, a React frontend for user interaction, and Pydantic models for data validation.
### Components
#### 1. FastAPI Endpoint (Backend)
The following FastAPI endpoint handles the conversion of feedback text into speech:
```python
# ai_voice_feedback.py
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
import os
import requests
from elevenlabs import generate_speech, set_api_key
set_api_key("your-api-key-here") # Replace with your API key
app = FastAPI()
@app.post("/convert-to-speech")
async def convert_to_speech_endpoint(feedback: str):
try:
response = generate_speech(feedback) # Simplified AI model interaction
if not response:
raise HTTPException(status_code=503, detail="AI service unavailable")
audio_path = "generated_audio.mp3"
with open(audio_path, 'wb') as f:
f.write(response)
return FileResponse(
audio_path,
media_type="audio/mpeg",
filename="feedback_audio.mp3"
)
except Exception as e:
raise HTTPException(status_code=500, detail=str(e))
if __name__ == "__main__":
uvicorn.run(app, host="0.0.0.0", port=8000)
2. React UI Component (Frontend)
The React component provides a user interface for submitting feedback and playing the generated audio:
// VoiceFeedback.js
import React, { useState } from 'react';
import { FaMicrophoneAlt, FaCircle, FaCheckCircle } from 'react-icons/fa';
const VoiceFeedback = () => {
const [isProcessing, setIsProcessing] = useState(false);
const [audioUrl, setAudioUrl] = useState(null);
const handleConvert = async (e) => {
e.preventDefault();
setIsProcessing(true);
try {
const formData = new FormData();
formData.append('feedback', document.getElementById('feedbackInput').value);
const response = await fetch('/convert-to-speech', {
method: 'POST',
body: formData
});
if (!response.ok) throw new Error('Failed to generate speech');
const blob = await response.blob();
setAudioUrl(window.URL.createObjectURL(blob));
} catch (error) {
console.error('Error:', error);
} finally {
setIsProcessing(false);
}
};
return (
<div className="feedback-container">
<form onSubmit={handleConvert}>
<textarea
id="feedbackInput"
placeholder="Enter your feedback here..."
className="feedback-input"
required
/>
<button type="submit" className="convert-button">
{isProcessing ? (
<><FaCircle className="loader"/><span>Generating...</span></>
) : (
<><FaMicrophoneAlt/><span>Generate Speech</span></>
)}
</button>
</form>
{audioUrl && (
<div className="audio-player">
<audio src={audioUrl} controls />
</div>
)}
</div>
);
};
export default VoiceFeedback;
3. Pydantic Data Schema
The following schema defines the data model for feedback conversion:
# schemas.py
from pydantic import BaseModel
class FeedbackText(BaseModel):
feedback: str = ...
Usage
- Backend Setup: Run the FastAPI server to start handling requests.
- Frontend Integration: Include the React component in your application for user interaction.
- Environment Configuration: Ensure that the AI service API key is securely set and available.
Example Workflow
- User Input: The user enters feedback text into the provided input field.
- Conversion Trigger: Upon submission, the feedback is sent to the FastAPI endpoint.
- Processing: The FastAPI endpoint processes the request using an AI model to generate speech.
- Output: The generated audio file is returned and can be played or downloaded by the user.
Error Handling
The system handles errors such as empty input, API service unavailability, and processing failures gracefully. It provides meaningful feedback to users through both frontend UI changes and HTTP error responses.
Security Considerations
Implement measures like CORS middleware in FastAPI and secure storage of AI service keys to ensure the tool is used securely.
Dependencies
- Python:
fastapi,uvicorn,elevenlabs-sdk - JavaScript: React, react-icons
- Pydantic: For data validation in FastAPI endpoints
Conclusion
The AI Voice Feedback Tool combines a robust backend with an intuitive frontend to provide an accessible and efficient way to generate spoken feedback. The integration of FastAPI for processing and Pydantic for data validation ensures reliability and scalability.
