Description

Business logic layer that wraps Flutter's speech_to_text package and manages the full recognition session lifecycle. Delegates to the platform's native engine (SFSpeechRecognizer on iOS, SpeechRecognition on Android), handles interim and final results, and exposes a clean API to UI components. No audio data leaves the device.
