Call Volume Adjustment Using Noise and Uplink Voice Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile phone systems lack intelligent volume adjustment solutions for voice conversations, which are distinct from music playing scenes, leading to suboptimal user experience due to inconsistent volume settings.
Innovation Solution
A method and terminal that collect sound data during voice conversations, including uplink voice and background noise, to adjust downlink voice data volume in real-time based on energy, power, or average volume parameters, adapting to environmental noise levels and user speaking patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal uses preset volume levels for voice conversations, then the device complexity is low, but the adaptability to different environments is poor
Solution Approach 1:
The terminal automatically adjusts the volume of downlink voice data by collecting sound data and calculating volume parameters itself, without requiring manual user intervention or complex external control systems. The device serves itself by using its own microphone input to determine appropriate volume levels
Solution Approach 2:
The terminal collects sound data from the environment through the microphone, calculates volume parameters based on this feedback, and uses this information to automatically adjust the downlink voice volume. This closed-loop feedback mechanism enables adaptive volume control without increasing overall system complexity
2Adaptability or versatility
If the terminal manually adjusts volume based on user feedback, then the adaptability to user needs is good, but the loss of time for volume adjustment is high
Solution Approach 1:
The terminal automatically performs volume adjustment without requiring user intervention. The device collects sound data, calculates volume parameters, and adjusts downlink voice volume autonomously, eliminating the time users would otherwise spend manually adjusting volume controls
Solution Approach 2:
The system continuously monitors sound data and automatically adjusts volume based on real-time environmental conditions, eliminating the need for users to provide feedback and wait for adjustment. The automatic feedback loop instantly adapts volume to current listening conditions
3Adaptability or versatility
If the terminal collects and processes sound data in real-time, then the adaptability to environment is improved, but the use of energy increases
Solution Approach 1:
The terminal processes only the necessary portion of sound data - specifically focusing on calculating volume parameters from microphone input - rather than performing comprehensive audio analysis. This partial processing approach achieves adaptive volume control with reduced energy consumption compared to full sound processing
4Measurement precision
If the terminal uses different microphones for sound data and background noise, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The terminal divides the audio collection function into separate components - using one microphone for sound data and another for background noise - allowing independent optimization of each measurement channel. This segmentation improves measurement precision while keeping the overall device structure manageable
Data Source
AI summary
A volume adjustment method and a terminal relate to the field of terminal technologies and applied to adaptively adjust a volume during a voice conversation, and improve user experience. The terminal collects sound data during a voice conversation, where the sound data includes uplink voice data and background noise, and adjusts, when receiving downlink voice data, a volume of the downlink voice data based on the sound data.
