MICROPHONE SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18320656 titled 'MICROPHONE SYSTEM

Simplified Explanation

The patent application describes a microphone system that can classify speech sounds and noise in an acoustic space based on reflection sound values. The system collects sound using a microphone and then categorizes the sound into speech sounds made by humans and other types of noise. The classified speech sounds are then sent to a speech recognition device for further processing.

  • The system uses a microphone to collect sound in an acoustic space.
  • It classifies the collected sound into speech sounds and noise based on reflection sound values.
  • The classified speech sounds are sent to a speech recognition device for analysis.

Potential Applications

  • Speech recognition systems: The technology can be used in speech recognition devices to improve accuracy by filtering out noise and focusing on speech sounds.
  • Voice-controlled devices: It can be applied in devices like smart speakers or virtual assistants to enhance voice recognition capabilities in noisy environments.
  • Telecommunications: The system can be used in call centers or teleconferencing systems to improve the quality of speech transmission by reducing background noise.

Problems Solved

  • Noise interference: The technology helps to distinguish speech sounds from background noise, improving the accuracy of speech recognition systems in noisy environments.
  • Reflection sound impact: By considering reflection sound values, the system can better classify speech sounds and noise, reducing false positives or negatives in the classification process.

Benefits

  • Improved speech recognition accuracy: By filtering out noise, the system enhances the performance of speech recognition devices, leading to more accurate transcriptions or commands.
  • Enhanced user experience: Voice-controlled devices can better understand and respond to user commands, even in noisy surroundings.
  • Clearer communication: In telecommunication systems, the technology reduces background noise, resulting in clearer and more intelligible conversations.


Original Abstract Submitted

A microphone system causes a microphone disposed in an acoustic space to collect sound, classifies a sound included in a sound data related to the sound collected by the microphone into a type of speech sound of a human present in the acoustic space and a type of noise that is a sound other than the speech sound based on a value related to a reflection sound reflected in the acoustic space, and outputs data related to the classified speech sound to a speech recognition device.
