AUDIO PROCESSING APPARATUS, AUDIO PROCESSING METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240282325 titled 'AUDIO PROCESSING APPARATUS, AUDIO PROCESSING METHOD, AND RECORDING MEDIUM
Simplified Explanation:
This patent application describes an audio processing apparatus that can remove unwanted audio components from an audio signal collected by a microphone in a space, based on the level of a reference signal reproduced by a speaker in the same space. The apparatus then outputs a replacement signal to a speech recognition device, which can be either comfort noise or a mute signal.
- The processor receives an audio signal from a microphone.
- It compares the level of a reference signal reproduced by a speaker to a threshold.
- If the level is equal to or greater than the threshold, the processor removes the audio component of the reference signal from the audio signal.
- It then outputs a replacement signal to the speech recognition device, which can be comfort noise or a mute signal.
Potential Applications: - Speech recognition systems - Noise cancellation technology - Audio processing in smart devices
Problems Solved: - Eliminating unwanted audio components from audio signals - Improving speech recognition accuracy in noisy environments
Benefits: - Enhanced speech recognition performance - Improved user experience in noisy environments - Better audio quality in audio processing applications
Commercial Applications: Title: Advanced Audio Processing Technology for Speech Recognition Systems This technology can be used in smart speakers, voice assistants, conference call systems, and other audio processing devices to enhance speech recognition accuracy and overall audio quality.
Prior Art: Prior art related to this technology may include patents or research papers on noise cancellation, audio signal processing, and speech recognition systems.
Frequently Updated Research: Researchers are constantly exploring new algorithms and techniques to improve noise cancellation and speech recognition performance in various audio processing applications.
Questions about Audio Processing Technology: 1. How does this technology compare to traditional noise cancellation methods? - This technology differs by using a reference signal from a speaker to remove unwanted audio components, providing more accurate noise cancellation. 2. What are the potential limitations of this audio processing apparatus in real-world applications? - The effectiveness of this technology may vary depending on the quality of the microphone, speaker, and surrounding environment.
Original Abstract Submitted
an audio processing apparatus includes a processor coupled to a memory. the processor receives an audio signal from a microphone serving to collect sound in a space. the processor determines whether a level of a reference signal is equal to or greater than a threshold. the reference signal is a reproduction signal reproduced by a speaker serving to output audio sound to the space. the processor outputs, as an output signal to a speech recognition device, a removal signal obtained by removing an audio component of the reference signal from the audio signal. the processor outputs, as an output signal to the speech recognition device, a replacement signal in place of the removal signal in response to determining that the level of the reference signal is equal to or greater than the threshold. the replacement signal is at least one of comfort noise and a mute signal.
