Abstract: An audio playback system is provided to facilitate adaptive output of audio content, such as spoken word content, by an audio player in response to detecting noise interferences such as external noise outside of the playback system and/or a noise indicator that external noise is about to occur. The playback system utilizes a natural skip back point found in the audio content for playback when audio content is disrupted by external noise. Content features are used to determine the skip back point in the audio content. The audio content is replayed from such a skip back point in a manner that provides a smooth transition to pre-played content and enables a listener to follow the content. Detection of multiple interfering noises within a condensed period of time are addressed to limit redundant and time consuming playbacks.
