React Native Voice AI Integration

I have a React Native application ready for its next upgrade: real-time voice interaction. The goal is to embed two concrete AI voice features—speech-to-text and text-to-speech—so users can both speak to the app and have it talk back naturally. Here is what I need from you: • Integrate reliable speech-to-text that works on both iOS and Android, handling accents and noisy environments gracefully. • Add natural-sounding text-to-speech with multiple voices and adjustable pitch/rate. • Keep all processing on-device when possible; fall back to cloud services only when accuracy demands it. • Deliver clean, well-commented React Native code (TypeScript preferred) plus any native modules or bridge code required. • Supply a brief README describing setup, API keys, and how to extend or switch providers. Acceptance criteria 1. A demo screen where users tap a mic, speak, and see text appear with <300 ms latency on current devices. 2. A second screen where entered text is spoken aloud; voice selection and rate controls function without reload. 3. No console warnings or crashes on the latest React Native LTS. 4. Clear documentation that lets another dev reproduce the build in under 15 minutes. If you have handled voice features before with tools such as Google Speech, Azure Cognitive Services, or local libraries like Vosk and react-native-tts, you will feel right at home. Let’s bring smart voice to this app!
