 ### Content extraction
 
+Audio content extraction is the process of isolating and retrieving specific elements or features from an audio file. This process can include separating individual audio sources; identifying specific segments within a sound file; or detecting and categorizing various characteristics of the audio content.
+
 #### Language handling
 We support different options to handle language processing during transcription.
 
 The following table provides an overview of the options controlled via the 'locales' configuration:
 
 |Locale setting|File size|Supported processing|Supported locales|Result latency|
