## Voice capture

`VoiceCaptureSession` (`isSupported`, `snapshot`, `subscribe`, `start`, `stop`, `cancel`, `dispose`) wraps the native speech recognizers; see [Voice capture](/client-sdks/react-native-sdk/guides/voice-capture.md). `stop()` resolves with `VoiceCaptureResult`; failures are `VoiceCaptureError` with a stable `code`.
