# captureSession

The underlying capture session.

```
final var captureSession: AVCaptureSession { get }
```

## Discussion

This property’s value is the new capture session created by [`providerWithSession(from:compatibleWith:priority:)`](/documentation/Speech/CaptureInputSequenceProvider/providerWithSession(from:compatibleWith:priority:)) or the existing capture session passed to [`provider(from:in:compatibleWith:priority:)`](/documentation/Speech/CaptureInputSequenceProvider/provider(from:in:compatibleWith:priority:)) or the initializer.

Use the methods of `AVCaptureSession` to start, stop, or manage the capture session.
