 `Transcription` is an extended feature of the class `Call`. You first need to obtain the transcription feature API object
 
 ```js
-const callTranscriptionApi = call.api(Features.Transcription);
+const callTranscriptionFeature = call.feature(Features.Transcription);
 ```
 
 You can check state of the transcription in the property `isTranscriptionActive`. If value is set to `true`, then transcription is active.
 
 ```js
-const isTranscriptionActive = callTranscriptionApi.isTranscriptionActive;
+const isTranscriptionActive = callTranscriptionFeature.isTranscriptionActive;
 ```
 
 You can subscribe to event, that is triggered when state of transcription changes:
 
 ```js
 const isTranscriptionActiveChangedHandler = () => {
-  console.log(callTranscriptionApi.isTranscriptionActive);
+  console.log(callTranscriptionFeature.isTranscriptionActive);
 };
-callRecordingApi.on('isTranscriptionActiveChanged', isTranscriptionActiveChangedHandler);
+callTranscriptionFeature.on('isTranscriptionActiveChanged', isTranscriptionActiveChangedHandler);
 ```
 
 You can unsubscribe from the event with the following code: 
 
 ```js
-callRecordingApi.off('isTranscriptionActiveChanged', isTranscriptionActiveChangedHandler);
+callTranscriptionFeature.off('isTranscriptionActiveChanged', isTranscriptionActiveChangedHandler);
 ```
