Methods, Systems, and Devices for Spectrally Adjusting Audio Gain in Videoconference and Other Applications - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240046950 titled 'Methods, Systems, and Devices for Spectrally Adjusting Audio Gain in Videoconference and Other Applications
Simplified Explanation
The abstract describes an electronic device that includes an imager and an audio input. The imager captures images of a subject using the device, while the audio input receives acoustic signals from the subject's mouth. The device uses one or more processors to determine if the subject's mouth is oriented on-axis or off-axis relative to the audio input. When the mouth is off-axis, the processors adjust the gain of the audio input for a subset of audible frequencies.
- The device captures images of a subject and receives audio signals from their mouth.
- Processors analyze the images to determine the orientation of the subject's mouth relative to the audio input.
- If the mouth is off-axis, the gain of the audio input is adjusted for certain audible frequencies.
Potential Applications:
- Enhancing audio quality during video calls or recordings by adjusting the gain based on the subject's mouth orientation.
- Improving speech recognition accuracy by optimizing audio input based on the subject's mouth position.
- Assisting individuals with hearing impairments by automatically adjusting audio settings based on mouth orientation.
Problems Solved:
- Off-axis mouth orientation can result in reduced audio quality and intelligibility. This technology solves this problem by adjusting the gain of the audio input.
- Inaccurate speech recognition caused by off-axis mouth orientation can be improved by optimizing the audio input.
Benefits:
- Improved audio quality and intelligibility during video calls, recordings, or other audio-based interactions.
- Enhanced accuracy of speech recognition systems, leading to better voice command recognition or transcription.
- Increased accessibility for individuals with hearing impairments, providing a more personalized and optimized audio experience.
Original Abstract Submitted
an electronic device includes an imager capturing one or more images of a subject engaging the electronic device and an audio input receiving acoustic signals having audible frequencies from the mouth of the subject engaging the electronic device. one or more processors determine from the one or more images of the subject whether the mouth of the subject is oriented on-axis relative to the audio input or off-axis relative to the audio input. the one or more processors adjust a gain of the audio input associated with a subset of the audible frequencies when the mouth of the subject is oriented off-axis relative to the audio input.
