Abstract: Processes, methods, systems, and devices are disclosed for intelligently detecting speech or in audio signals and smoothly transitioning to mode that enables a user to better understand the speech. For example, aspects of the present disclosure provide method for processing and producing audio signals. During playback of an audio signal, the method analyzes content of the audio signal prior to the playback of the content to determine whether one or more predefined conditions are met to indicate that the content includes speech. In response to determining the one or more predefined conditions are met, the method automatically applies to the audio signal a first playback equalization configured to enhance the speech within the content. In response to determining the one or more predefined conditions are not met, the method comprises applying to the audio signal no playback equalization or a second playback equalization different from the first playback equalization.
