SOUND COLLECTING DEVICE, SOUND COLLECTING METHOD, AND SOUND COLLECTING PROGRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18677136 titled 'SOUND COLLECTING DEVICE, SOUND COLLECTING METHOD, AND SOUND COLLECTING PROGRAM
Simplified Explanation: This patent application describes a system that converts vibrations transmitted to a human body into voice signals using an adaptive filter.
- The microphone generates a voice signal based on air vibration.
- The vibration sensor generates a vibration signal based on vibration transmitted to a human body.
- An adaptive filter multiplies the vibration signal by a coefficient to generate a converted voice signal.
- A subtractor generates a residual signal that is the difference between the voice signal and the converted voice signal.
- The adaptive controller updates the coefficient of the adaptive filter based on whether the signal is determined to be a voice section or a non-audio section.
Potential Applications: 1. Assistive communication devices for individuals with speech impairments. 2. Noise cancellation systems in audio equipment. 3. Voice recognition technology in smart devices.
Problems Solved: 1. Converting vibrations into voice signals for communication. 2. Enhancing audio quality by reducing background noise. 3. Improving voice recognition accuracy in various applications.
Benefits: 1. Enhanced communication for individuals with speech disabilities. 2. Improved audio quality in noisy environments. 3. Increased accuracy in voice recognition systems.
Commercial Applications: Potential commercial applications include assistive communication devices, audio equipment, and smart devices with voice recognition capabilities.
Prior Art: Readers can explore prior patents related to adaptive filters, voice signal processing, and vibration sensors in the field of audio technology.
Frequently Updated Research: Stay updated on advancements in adaptive filter technology, voice signal processing, and vibration sensor applications for audio devices.
Questions about the Technology: 1. How does the adaptive filter in this system improve voice signal conversion? 2. What are the potential limitations of converting vibrations into voice signals using this technology?
Original Abstract Submitted
A microphone generates a voice signal based on air vibration. A vibration sensor generates a vibration signal based on vibration transmitted to a human body. An adaptive filter multiplies the vibration signal by a coefficient to generate a converted voice signal. A subtractor generates a residual signal that is a difference between the voice signal and the converted voice signal. The adaptive controller controls the adaptive filter to update the coefficient so that the residual signal becomes small at a first speed when it is determined to be a voice section, and controls the adaptive filter to update the coefficient so that the residual signal becomes small at a second speed slower than the first speed when it is determined to be a non-audio section, or supplies the adaptive filter control signal to the adaptive filter to control not to update the coefficient.
