How do you integrate Voice AI in React Native?
Integrate Voice AI in React Native using speech-to-text libraries (Whisper, @react-native-voice/voice), text-to-speech (expo-speech), and AI processing (OpenAI, Claude). Implement real-time transcription, voice commands, and conversational interfaces. AI Mobile Launcher includes pre-built voice modules with offline Whisper support and multi-language recognition.
Voice AI is transforming how users interact with mobile applications. With over 50% of adults using voice search daily and voice commerce growing rapidly, integrating voice AI capabilities is essential for modern mobile apps.
What are the core Voice AI technologies?
Understanding the fundamental technologies behind voice AI:
- Speech Recognition (ASR) - Converting spoken language to text
- Natural Language Processing (NLP) - Understanding and processing human language
- Text-to-Speech (TTS) - Converting text back to natural-sounding speech
- Voice Activity Detection (VAD) - Detecting when users are speaking
What libraries do you need for Voice AI in React Native?
Essential libraries for voice AI integration:
// Voice AI integration setup
import Voice from '@react-native-voice/voice';
import Tts from 'react-native-tts';
class VoiceAIManager {
constructor() {
this.setupVoiceRecognition();
this.setupTextToSpeech();
}
setupVoiceRecognition() {
Voice.onSpeechStart = this.onSpeechStart;
Voice.onSpeechEnd = this.onSpeechEnd;
Voice.onSpeechResults = this.onSpeechResults;
Voice.onSpeechError = this.onSpeechError;
}
setupTextToSpeech() {
Tts.setDefaultLanguage('en-US');
Tts.setDefaultRate(0.5);
}
async startListening() {
try {
await Voice.start('en-US');
} catch (error) {
console.error('Voice recognition error:', error);
}
}
async stopListening() {
try {
await Voice.stop();
} catch (error) {
console.error('Stop listening error:', error);
}
}
speak(text: string) {
Tts.speak(text);
}

People Also Ask
Can Voice AI work offline?
Yes, using Whisper.cpp or react-native-whisper for on-device speech recognition. AI Mobile Launcher includes offline voice processing that works without internet connectivity.
Which is better: Whisper or Google Speech-to-Text?
Whisper offers better accuracy for diverse accents and works offline. Google Speech-to-Text has lower latency but requires internet. AI Mobile Launcher supports both approaches.
