METHOD AND APPARATUS FOR DYNAMIC DIRECITONAL VOICE RECEPTION WITH MULTIPLE MICROPHONES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240029756 titled 'METHOD AND APPARATUS FOR DYNAMIC DIRECITONAL VOICE RECEPTION WITH MULTIPLE MICROPHONES

Simplified Explanation

The abstract describes a speakerphone that includes multiple microphones and a memory device. It also includes a DSP (Digital Signal Processor) to process audio waves received by the microphones and determine the direction of the user's voice. The DSP also filters out background noises and voices from outside the coverage area.

  • The speakerphone includes a memory device, PMU, and three microphones to receive audio waves.
  • A DSP is used to process the audio waves received by the microphones.
  • The DSP determines the wave phases of the audio waves to calculate the direction of the user's voice relative to the speakerphone.
  • The voice direction of the user is locked in by the speakerphone.
  • The DSP also processes the user's voice to detect characteristics and filters out background noises and voices from outside the coverage area.

Potential Applications:

  • Conference calls: The speakerphone can accurately capture the direction of the user's voice, making it suitable for conference calls where multiple participants are involved.
  • Voice recognition systems: The technology can be used in voice recognition systems to filter out background noises and improve the accuracy of voice recognition.
  • Smart home devices: Speakerphones with this technology can be integrated into smart home devices to enhance voice commands and eliminate interference from background noises.

Problems Solved:

  • Background noise interference: The technology solves the problem of background noises and voices affecting the clarity of the user's voice during audio communication.
  • Voice direction determination: The speakerphone accurately determines the direction of the user's voice, allowing for better audio capture and localization.

Benefits:

  • Improved audio quality: By filtering out background noises and voices, the speakerphone provides clearer and more intelligible audio during communication.
  • Accurate voice direction detection: The technology ensures that the speakerphone can accurately determine the direction of the user's voice, enhancing the overall user experience.
  • Enhanced voice recognition: By filtering out background noises, the technology improves the accuracy of voice recognition systems, making them more reliable and efficient.


Original Abstract Submitted

a speakerphone may include a memory device, a pmu, a first microphone, a second microphone, and a third microphone, each, to receive audio waves. the speakerphone also includes a dsp to process the audio waves received by the first microphone, second microphone, and third microphone to determine the wave phases of the audio waves received by the first microphone, second microphone, and third microphone to calculate a direction of a voice of a user relative to the speakerphone, lock in the voice direction of the user relative to the speakerphone, and process the voice of the user to detect characteristics of the user's voice and filter out background noises and background voices from outside an angular field coverage for the voice direction of the user.
