Voice Analysis for User Profiling in Media Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for creating user profiles in media devices are intrusive and often result in incomplete or inaccurate information, leading to irrelevant advertisements and content suggestions, as users find them inconvenient and may provide dishonest answers.
Innovation Solution
A media device that uses voice recognition and analysis to detect user speech, determining demographic information and interests without requiring lengthy questionnaires, allowing for targeted advertisements and content recommendations based on voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional questionnaires are used to create user profiles, then user profile information can be collected, but user convenience deteriorates and information accuracy deteriorates
Solution Approach 1:
The system automatically collects user profile information through voice analysis without requiring users to manually fill out questionnaires. The voice recognition system analyzes speech characteristics, tone, and content to autonomously generate demographic and interest data, eliminating the need for user input while maintaining information accuracy
Solution Approach 2:
The patent replaces the mechanical questionnaire-form-filling process with an acoustic field-based voice analysis system. Instead of requiring users to physically interact with form fields and type answers, the system uses microphones and signal processing to capture and analyze voice data, converting acoustic energy into useful profile information
2Ease of operation
If users answer questionnaire questions quickly, then user convenience improves, but information accuracy deteriorates due to potentially dishonest or incomplete answers
Solution Approach 1:
The system performs self-service analysis by automatically interpreting voice characteristics and speech content without relying on user self-reporting. The voice analysis algorithm independently determines demographic information and interests based on acoustic features, eliminating the possibility of dishonest or rushed answers while maintaining high accuracy
Solution Approach 2:
The system continuously monitors and analyzes voice input in real-time, providing immediate feedback through the voice recognition interface. This ongoing analysis ensures that profile information is accurately captured as users naturally speak, rather than requiring them to deliberately provide answers to structured questions
3Ease of operation
If voice analysis is used to create user profiles, then user convenience improves by eliminating questionnaires, but device complexity increases
Solution Approach 1:
The voice recognition system serves multiple functions simultaneously: it processes user commands, analyzes speech characteristics for demographic profiling, and extracts interest information from conversation content. By making the voice analysis component multi-functional, the system avoids adding separate dedicated systems for each function, thereby limiting the increase in overall device complexity
Solution Approach 2:
The patent merges the voice command processing function with the user profile creation function into a single integrated voice analysis system. Instead of having separate modules for command recognition and demographic data collection, the system combines these operations, processing both tasks through the same acoustic signal analysis pipeline
Data Source
AI summary
An aspect of the present invention is drawn to an audio data processing device for use by a user to control a system and for use with a microphone, a user demographic profiles database and a content/ad database. The microphone may be operable to detect speech and to generate speech data based on the detected speech. The user demographic profiles database may be capable of having demographic data stored therein. The content/ad database may be capable of having at least one of content data and advertisement data stored therein. The audio data processing device includes a voice recognition portion, a voice analysis portion and a speech to text portion. The voice recognition portion may be operable to process user instructions based on the speech data. The voice analysis portion may be operable to determine characteristics of the user based on the speech data. The speech to text portion may be operable to determine interests of the user.
