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.
