Video Parameter Adjustment via Voiceprint Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart terminals, such as smart TVs, cannot automatically adjust playback parameters like image mode and sound mode based on user identity and mood, leading to a suboptimal user experience.
Innovation Solution
A method and device for adjusting video parameters based on voiceprint recognition, which involves collecting audio information, determining user identity and mood information, and adjusting video playback parameters accordingly using a parameter adjustment mode and adjustment ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of playback parameters is used, then users can control image and sound settings, but the system cannot automatically adapt to different users and moods
Solution Approach 1:
The system automatically identifies user identity through voiceprint recognition and detects mood through audio analysis, then self-adjusts playback parameters without requiring manual user input. The smart terminal serves itself by autonomously selecting appropriate image and sound modes based on recognized user characteristics and emotional state.
Solution Approach 2:
The patent replaces the mechanical manual adjustment system with an automated voice-based recognition and control system. Instead of physical button presses or menu navigation, the system uses voiceprint analysis and audio processing to automatically control playback parameters, substituting mechanical interaction with acoustic field-based control.
2Adaptability or versatility
If automatic adjustment based on voiceprint recognition is implemented, then personalized playback parameters can be provided, but the device complexity increases
Solution Approach 1:
The audio processing system performs multiple functions simultaneously: it captures audio input, conducts voiceprint recognition for user identification, analyzes audio characteristics for mood detection, and triggers parameter adjustments. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while achieving personalization.
Solution Approach 2:
The patent combines voiceprint recognition, mood detection, and parameter control into an integrated system. The audio processing module serves as a unified entry point that handles user identification, emotional state analysis, and subsequent playback parameter adjustment, merging multiple functions into a single coordinated process rather than separate independent systems.

AI summary
Disclosed are a method for adjusting a video parameter based on voiceprint recognition, a device for adjusting a video parameter based on voiceprint recognition and a readable storage medium, where the method includes: during a video program is displayed on a smart terminal, receiving audio information collected by a voiceprint data collection module (S100); in a determination that a voiceprint feature library includes target preset audio information corresponding to the audio information, determining user identity information and user mood information corresponding to the audio information based on the target preset audio information (S200); acquiring an adjustment parameter of a parameter adjustment mode corresponding to the user mood information, and acquiring an adjustment ratio corresponding to the parameter adjustment mode based on the user identity information (S300); and adjusting a video playback parameter of the smart terminal based on the adjustment parameter and the adjustment ratio (S400). This application may automatically adjust the video playback parameter of the smart terminal according to the user identity information and the user mood information corresponding to the audio information, thereby realizing intelligent adjustment of the video playback parameter of the smart terminal, and improving the user experience.
