Audio Presentation Segmentation via Speaker Tone Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method to link and present relevant content to users based on user selection, particularly from public sources, failing to effectively utilize machine learning and natural language processing to analyze and tag key points in audio and video presentations.
Innovation Solution
A content linking system that employs machine learning algorithms, natural language processing, and signal processing techniques to analyze audio and video data, identifying key points and themes, and generating metadata to tag important sections, which are then used to provide users with summaries and highlight areas of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated analysis of audio and video presentations is implemented, then content tagging efficiency is improved, but system complexity increases
Solution Approach 1:
The system segments the audio and video presentation analysis into distinct functional modules: audio processing module, video processing module, metadata generation module, and content tagging module. Each module handles specific tasks independently, improving processing efficiency while managing system complexity through modular architecture.
Solution Approach 2:
The patent introduces an intermediary processing layer that converts raw audio and video data into structured metadata before final content tagging. This intermediary step simplifies the overall system by creating a standardized intermediate representation that bridges complex input data and the tagging output.
2Measurement precision
If machine learning algorithms are used to identify key points, then content accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary processing of audio and video presentations to extract basic features and generate initial metadata before applying machine learning algorithms. This preliminary action prepares the data in advance, allowing the ML models to work with pre-processed inputs and reduce overall processing time while maintaining accuracy.
Solution Approach 2:
The patent applies machine learning selectively to identify key points and themes rather than analyzing every aspect of the presentation in detail. By focusing ML resources on critical segmentation and tagging tasks rather than complete content analysis, the system achieves good accuracy with reduced processing time.
Data Source
AI summary
Examples related to methods and systems for analyzing presentation digital data, which may include extracting speaker audio data from the audio data of the presentation digital data and analyzing the speaker audio data to identify a characteristic of the speaker audio data, such as tone, frequency, cadence, and volume. Portions of the presentation digital data are then identified based on changes in the characteristic of the speaker audio data. The identified portions of the presentation digital data are automatically tagged based on the characteristic of the speaker audio data. The identified portions of the presentation digital data and associated tags are stored for retrieval. This method provides a way to efficiently analyze presentation digital data and retrieve specific portions of interest based on the characteristic of the speaker audio data.
