Adaptive Voice Response Volume Control for Muted Audio Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic user devices face challenges in controlling the amplitude of audio output in response to voice inputs, often resulting in undesirable loudness or inaudibility, especially when the device is muted or in quiet environments, leading to user embarrassment or missed notifications.
Innovation Solution
Implementing a smart audio output volume control method that dynamically adjusts the output volume based on the input volume level of the received voice command, allowing for real-time correlation and resetting to a pre-set volume or mute setting after the response, ensuring the audio output is audible without being disruptive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device media volume is set to a fixed level for audio output, then the audio response is consistently audible, but the output may be too loud in quiet environments or too soft in noisy environments
Solution Approach 1:
The patent implements dynamic volume adjustment by detecting the ambient noise level and automatically adjusting the media volume accordingly. The system transitions from a static fixed volume setting to a dynamic adaptive setting that changes based on environmental conditions, resolving the contradiction between consistent audibility and environmental adaptability
Solution Approach 2:
The system uses feedback from the ambient noise detection mechanism to continuously monitor the acoustic environment and adjust the media volume in response. This closed-loop feedback system allows the device to adapt to changing environmental conditions while maintaining reliable audio output
2Reliability
If the device unmutes and sets audio output to a fixed volume level before announcing audio output, then the voice readouts become audible when the device was muted, but the output can be very loud and disruptive in certain situations
Solution Approach 1:
The patent changes the volume parameter dynamically based on ambient noise detection rather than using a fixed volume level. By adjusting the media volume parameter according to the detected acoustic environment, the system ensures voice readouts are audible without being excessively loud or disruptive, eliminating user embarrassment in public settings
3Ease of operation
If the audio output volume is set to match the device's preset media volume, then the output is consistent with user expectations, but it cannot adapt to different acoustic environments or user preferences
Solution Approach 1:
The system transitions from a static preset volume setting to a dynamic adaptive volume control that responds to ambient noise conditions. This allows the audio output to maintain consistency with user expectations while simultaneously adapting to different acoustic environments through automatic detection and adjustment

AI summary
A method implemented by processing and other audio components of an electronic device provides a smart audio output volume control, which correlates a volume level of an audio output to that of an audio input that triggered generation of the audio output. According to one aspect, the method includes: receiving an audio input that triggers generation of an audio output response from the user device; determining an input volume level corresponding to the received audio input; and outputting the audio output response at an output volume level correlated to the input volume level. The media output volume control level of the device is changed from a preset normal level, including from a mute setting, to the determined output level for outputting the audio output. Following, the media output volume control level is automatically reset to a pre-set volume level for normal media output.
