Method for enhancing speech in audio signals during playback
The patent application (Publication Number: US20240029755A1) describes a method for audio signal processing that involves analyzing the content of an audio signal before playback to determine if it contains speech. If speech is detected, a specific playback equalization is automatically applied to enhance the speech within the content. This method also allows for the analysis of metadata associated with the content, voice tracks, different channels, and sound environments to make informed decisions on playback equalization.
Furthermore, the patent application includes claims for an apparatus and a non-transitory computer-readable medium that can perform the same audio signal processing method. The apparatus includes a memory and a processor configured to analyze the audio signal content and apply the appropriate playback equalization based on predefined conditions. The computer-readable medium stores instructions for executing the audio signal processing method, ensuring that the device can automatically enhance speech in the content or apply alternative equalization based on the analysis performed before playback. Overall, this patent application introduces a novel approach to audio signal processing that prioritizes speech enhancement and customization of playback equalization based on the content of the audio signal.
