API Endpoint (FastAPI)
The following FastAPI endpoint handles incoming voice commands and processes them for navigation:
from fastapi import FastAPI, Request
from pydantic import VoiceCommand
import speech_to_text
app = FastAPI()
@app.post("/voice-command")
async def process_voice_command(request: Request, command: VoiceCommand):
"""
Processes a voice command and returns navigation instructions.
"""
# Convert voice command to text (handled by speech_to_text)
text_command = await speech_to_text.convert(command.command)
# Process the text command for navigation
response = {
"status": "success",
"command_received": text_command,
"navigation_instructions": generate_navigation(text_command)
}
return response
React UI Component
A simple React component for capturing voice commands and displaying navigation results:
import React, { useState } from 'react';
import Microphone from 'react-microphone';
const VoiceNavigation = () => {
const [command, setCommand] = useState('');
const [isListening, setIsListening] = useState(false);
const [result, setResult] = useState('');
const handleCommand = async (commandText) => {
try {
// Send command to backend and get navigation result
const response = await fetch('/voice-command', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({ command: commandText })
});
setResult('Processing...');
const data = await response.json();
setResult(data.navigation_instructions);
} catch (error) {
console.error('Error:', error);
setResult('Failed to process command');
}
};
return (
<div style={{ padding: '20px' }}>
<h1>Voice Navigation Assistant</h1>
<button
onClick={() => setIsListening(!isListening)}
style={{
padding: '10px 20px',
backgroundColor: isListening ? '#4CAF50' : '#f44336',
color: 'white',
border: 'none',
borderRadius: '5px'
}}
>
{isListening ? 'Stop Recording' : 'Start Recording'}
</button>
<Microphone
active={isListening}
onCommand={(text) => handleCommand(text)}
button={
<div>
{isListening ? (
<span>Recording...</span>
) : (
<span>Click to start recording</span>
)}
</div>
}
/>
{result && (
<div style={{ marginTop: '20px', padding: '15px', border: '1px solid #ddd' }}>
<h3>Navigation Result:</h3>
<p>{result}</p>
</div>
)}
</div>
);
};
export default VoiceNavigation;
Data Schema (Pydantic)
The data schema for voice commands and responses:
from pydantic import BaseModel
from typing import Optional
class VoiceCommand(BaseModel):
id: str
command: str # The voice command string
timestamp: int # Time when the command was received
user_id: Optional[str] = None # User ID for authentication purposes
device_id: str # Device identifier
class Config:
json_schema_extra = {
"example": {
"id": "12345",
"command": "navigate to the nearest gas station",
"timestamp": 1678901234,
"user_id": "user_123",
"device_id": "dev_456"
}
}
class NavigationResponse(BaseModel):
status: str
command_received: str
navigation_instructions: Optional[str] = None # The generated navigation instructions
class Config:
json_schema_extra = {
"example": {
"status": "success",
"command_received": "navigate to the nearest gas station",
"navigation_instructions": "Turn left on Main Street, then right on Oak Avenue..."
}
}
Notes
- The API endpoint uses FastAPI for efficient handling of voice commands.
- The React component integrates with a microphone library and sends/ receives data in JSON format.
- The Pydantic models ensure proper validation and serialization of voice command data.
- Actual implementation would require additional error handling, authentication, and integration with speech-to-text services like Google Speech API or Amazon Transcribe.
