Dynamic Playback Speed Adjustment for Audio Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media player applications require users to manually adjust playback speed, which can lead to a poor user experience, especially when transitioning between different types of audio content such as dialogue and music.
Innovation Solution
A computer-implemented method that analyzes the audio content to determine its type, such as dialogue or music, and automatically adjusts the playback speed and audio time stretching algorithm accordingly, thereby enhancing the user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If playback speed is increased to quickly go over media content, then productivity is improved, but user experience deteriorates due to difficulty in understanding dialogue
Solution Approach 1:
The playback speed is made dynamic and automatically adjusted based on the detected audio type. The system transitions from a static, manual speed setting to a dynamic, automated system that adapts playback speed in real-time according to whether the current segment contains dialogue or music, resolving the contradiction between fast consumption and comprehension quality.
Solution Approach 2:
The media player performs self-service by automatically detecting audio types and adjusting playback speed without requiring user intervention. The system analyzes the audio stream, identifies dialogue segments, and autonomously modifies playback parameters to maintain optimal user experience while enabling faster content consumption.
2Adaptability or versatility
If playback speed is manually adjusted by user, then adaptability to different audio types is improved, but device complexity increases due to manual intervention requirements
Solution Approach 1:
The system eliminates manual adjustment complexity by implementing self-service functionality. The media player automatically detects audio types (dialogue vs. music) through audio analysis and autonomously adjusts playback speed, removing the need for manual user intervention while maintaining high adaptability to different audio content types.
Solution Approach 2:
The system employs feedback mechanisms where the audio output is continuously analyzed, and the detected audio type feeds back to the playback speed control system. This closed-loop feedback enables automatic adaptation to different audio types without requiring complex manual adjustment interfaces.
3Productivity
If playback speed is increased during music segments, then productivity is improved, but user experience worsens due to distortion of music quality
Solution Approach 1:
Different playback speeds are applied to different segments of the media content based on local audio characteristics. Music segments are identified and played back at higher speeds while preserving quality, whereas dialogue segments are played at lower speeds to ensure comprehension. This local differentiation resolves the contradiction between fast playback and quality preservation.
Solution Approach 2:
The playback speed is dynamically adjusted based on the type of audio currently being played. The system transitions between different speed settings depending on whether music or dialogue is detected, enabling fast playback during music while maintaining quality, and slower playback during dialogue for comprehension.

AI summary
A computer implemented method for setting a playback speed of media content comprising audio, the media content having a defined normal playback speed, the method comprising: receiving an indication that the media content is to be played at a speed different from the normal playback speed of the media content, analysing the audio for determining a type of audio; and determining a playback speed different from the normal playback speed depending on the determined type of audio, and setting the playback speed of the media content to the determined playback speed.
