==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.
