==THRESHOLD GENERATION METHOD, THRESHOLD GENERATION DEVICE, AND COMPUTER PROGRAM PRODUCT - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240029713 titled 'THRESHOLD GENERATION METHOD, THRESHOLD GENERATION DEVICE, AND COMPUTER PROGRAM PRODUCT

==Simplified Explanation==

According to one embodiment, this patent application describes a method for generating a threshold to be used in a keyword detection device. The keyword detection device is used to determine if an audio signal contains a specific keyword by comparing a threshold with a keyword score, which represents the similarity between the voice in the audio signal and a preset keyword. 

The method for generating the threshold includes the following steps:
* Calculating keyword scores that represent the similarity between the keyword and a set of reference audio signals.
* Calculating parameters that represent the distribution of the keyword scores.
* Generating the threshold based on the parameters that represent the distribution of the keyword scores.

Potential applications of this technology:
* Voice recognition systems: This technology can be used in voice recognition systems to accurately detect specific keywords in audio signals.
* Security systems: It can be applied in security systems to identify specific keywords or phrases that may indicate a threat or suspicious activity.
* Transcription services: This technology can be used in transcription services to automatically detect and highlight specific keywords or phrases in audio recordings.

Problems solved by this technology:
* Accurate keyword detection: This technology improves the accuracy of keyword detection by generating a threshold based on the distribution of keyword scores, resulting in more reliable detection of keywords in audio signals.
* Efficient processing: By using a threshold, the keyword detection device can quickly determine if an audio signal contains the keyword, reducing the processing time and improving efficiency.

Benefits of this technology:
* Improved accuracy: The generated threshold based on the distribution of keyword scores helps in accurately detecting keywords in audio signals, reducing false positives and false negatives.
* Time-saving: The use of a threshold allows for faster processing of audio signals, enabling real-time keyword detection.
* Versatility: This technology can be applied in various fields such as voice recognition, security systems, and transcription services, providing a versatile solution for keyword detection.


==Original Abstract Submitted==

according to one embodiment, a threshold generation method includes generating a threshold to be set in a keyword detection device. the keyword detection device detects, based on a result of comparison of the threshold with a keyword score representing a degree of similarity between voice included in an audio signal and a preset keyword, whether the audio signal includes the keyword. the threshold generation method includes: calculating keyword scores representing degrees of similarity between the keyword and a plurality of reference audio signals; calculating parameters representing a distribution of a score set including the keyword scores calculated based on the reference audio signals; and generating the threshold based on the parameters representing the distribution of the score set.
