Some aspects of the disclosure relate to a system and methods for monitoring an audio signal that may comprise one or more device audio components, e.g., from a device presenting content and an ambient audio component. The system can determine the ambient audio component of the audio signal, and can determine whether the ambient audio component has satisfied an ambient audio component threshold. If the ambient audio component threshold has been satisfied, the system can cause the device to display a visual representation of the device audio component, such as presenting text corresponding to speech of the audio component.

A system capable of self-adjusting both sound level and spectral content to improve audibility and intelligibility of electronic device audible cues. Audible cues are stored as sound files. Ambient noise is detected, and the output of the audible cues is altered based on the ambient noise. Various embodiments include processed sound files that are more robust in noisy environments.
