+
+Call transcription is an extended feature of the core `Call` object. You first need to obtain the transcription feature object:
+
+```csharp
+TranscriptionCallFeature transcriptionFeature = call.Features.Transcription;
+```
+
+Then, to check if the call is being transcribed, inspect the `IsTranscriptionActive` property of `transcriptionFeature`. It returns `boolean`.
+
+```csharp
+boolean isTranscriptionActive = transcriptionFeature.isTranscriptionActive;
+```
+
+You can also subscribe to changes in transcription:
+
+```csharp
+private async void Call__OnIsTranscriptionActiveChanged(object sender, PropertyChangedEventArgs args)
+    boolean isTranscriptionActive = transcriptionFeature.IsTranscriptionActive();
+}
+
+transcriptionFeature.IsTranscriptionActiveChanged += Call__OnIsTranscriptionActiveChanged;
+```
