INFORMATION PROCESSING DEVICE, AND OUTPUT METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18239289 titled 'INFORMATION PROCESSING DEVICE, AND OUTPUT METHOD

Simplified Explanation

The abstract describes an information processing device that can process sound signals to enhance specific sound directions and suppress others. Here are the key points:

  • The device acquires information about the position of sound sources.
  • It extracts multiple sound feature values from mixed sound signals.
  • It emphasizes a sound feature value in a target sound direction based on the position information.
  • It estimates the target sound direction based on the position information.
  • It extracts a mask feature value based on the estimated target sound direction.
  • It generates a sound signal that emphasizes the target sound direction and another sound signal that masks it.
  • It outputs a target sound signal using the emphasized sound signal.

Potential applications of this technology:

  • Audio enhancement in teleconferencing systems to improve the clarity of the desired speaker's voice.
  • Noise cancellation in headphones or hearing aids to reduce unwanted background noise.
  • Directional audio systems in theaters or stadiums to focus sound towards specific areas or seats.
  • Virtual reality or augmented reality applications to enhance the spatial audio experience.

Problems solved by this technology:

  • Difficulty in hearing or understanding specific sound sources in noisy environments.
  • Inability to isolate or enhance specific sound directions in audio processing.
  • Lack of control over the directionality of sound signals in various applications.

Benefits of this technology:

  • Improved speech intelligibility and communication in noisy environments.
  • Enhanced listening experience by focusing on desired sound sources.
  • Increased immersion and realism in virtual reality or augmented reality applications.
  • Better audio quality and reduced distractions in various audio processing systems.


Original Abstract Submitted

An information processing device includes an acquisition unit that acquires sound source position information and so forth, a sound feature value extraction unit that extracts a plurality of sound feature values based on the mixed sound signal, an emphasis unit that emphasizes a sound feature value in a target sound direction based on the sound source position information, an estimation unit that estimates the target sound direction based on the sound source position information and so forth, a mask feature value extraction unit that extracts a mask feature value based on the estimated target sound direction and so forth, a generation unit that generates a target sound direction emphasis sound signal and generates a target sound direction masking sound signal, and a target sound signal output unit that outputs a target sound signal by using the target sound direction emphasis sound signal and so forth.
