Automatic Song Mode Switching via Vocal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current song playing modes require manual switching between listening and singing modes, leading to inflexible song playback as users need to restart the song after mode changes.
Innovation Solution
A method and apparatus that automatically switch between song listening and singing modes based on continuous user behaviors, such as mouth shape and voice following, allowing seamless transition by reducing the original vocal volume and switching to song accompaniment when appropriate behaviors are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching between song listening mode and song singing mode is implemented, then mode switching is achieved, but operation flexibility is reduced and time loss occurs due to replay requirement
Solution Approach 1:
The system automatically detects user singing behavior through voice analysis and autonomously switches between listening mode and singing mode without requiring manual user input. The device serves itself by monitoring its own playback state and making mode transitions based on detected user actions, thereby eliminating the need for manual mode switching operations and avoiding time loss from replays
Solution Approach 2:
The system continuously monitors user voice input during playback and uses this feedback to determine when to switch modes. By analyzing the presence and characteristics of user singing voices in real-time, the system dynamically adjusts the playback mode, creating a closed-loop control system that responds to user behavior without requiring explicit mode change commands
2Adaptability or versatility
If manual mode switching is required, then clear mode separation is maintained, but operation complexity increases and flexibility is reduced
Solution Approach 1:
The playback device automatically monitors its own operational state by detecting user singing behavior through its audio input capabilities. This self-monitoring mechanism enables the device to autonomously determine when to transition between listening and singing modes, eliminating the need for complex manual switching interfaces and increasing operational flexibility while maintaining clear mode separation through automatic detection

AI summary
A song playing method includes: playing an original vocal of a target song in a song listening mode; reducing a volume of the original vocal in response to a first continuous following behavior for the target song, the first continuous following behavior being a continuous following behavior made with playing progress of the target song; switching from the song listening mode to a song singing mode in response to a second continuous following behavior after the first continuous following behavior, the second continuous following behavior being different from the first continuous following behavior, and being a continuous following behavior that is made with the playing progress of the target song and is generated after the first continuous following behavior; and playing, in the song singing mode, a song accompaniment of the target song from song progress of the target song that is indicated by the original vocal.
