Earphone Volume Control Using Name Recognition in Mobile Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users wearing earphones often cannot hear others speaking to them, especially when the volume is high, as existing technologies lack an effective solution to automatically adjust the volume based on the identity of the person speaking.
Innovation Solution
A mobile device that recognizes the user's name through a microphone and processor, generating a volume control signal to lower the earphone volume when the user's name is detected, and optionally uses voice recognition and tonality analysis to identify the speaker and adjust the volume accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the earphone volume is increased to improve audio quality and user experience, then the user cannot hear others speaking to them, especially when the volume is high
Solution Approach 1:
The system continuously monitors the audio environment through the microphone, detects when the user's name is mentioned, and provides feedback by automatically adjusting the volume. This closed-loop feedback mechanism allows the system to respond dynamically to contextual cues, resolving the contradiction between maintaining high audio volume and being able to hear external speech.
Solution Approach 2:
The earphone volume is transformed from a static setting to a dynamic parameter that automatically adjusts based on real-time speech detection. The processor modulates the volume level in response to detected name mentions, creating a dynamic system that adapts to changing environmental conditions and resolves the fixed contradiction between high volume and external awareness.
2Ease of operation
If automatic volume adjustment based on name recognition is implemented, then users can hear important voices, but the device complexity increases
Solution Approach 1:
The mobile device's existing processor and microphone are utilized for dual purposes: their original functions plus name recognition and volume control. By making the existing components multi-functional, the system achieves automatic volume adjustment without adding significant hardware complexity, resolving the contradiction between enhanced operation and device simplicity.
Solution Approach 2:
The system uses the device's own existing resources (processor, memory, microphone) to perform the name recognition and volume control functions. Rather than requiring entirely new dedicated components, the existing system serves itself by leveraging its current capabilities for the additional function of contextual volume adjustment.
Data Source
AI summary
A mobile device has a memory storing a name of a user of the mobile device, an audio output interface for outputting an audio signal to earphones worn by the user of the mobile device and a microphone configured to receive a sound signal external to the earphones. A processor is communicatively connected to the microphone to process the sound signal to recognize speech in response to the processor detecting that the audio output interface is outputting the audio signal to the earphones. The processor is configured to determine if the speech includes the name of the user stored in the memory of the mobile device. The processor is configured to generate and provide a volume control signal to the audio output interface to lower a volume of the earphones in response to determining that the speech includes the name of the user.
