Latest Patents
One of Simyung Chang's latest patents is titled "Dummy prototypical networks for few-shot open-set keyword spotting." This innovation provides systems and techniques for processing audio data, utilizing a dummy prototypical network to perform few-shot open-set keyword spotting (FSOS-KWS). The process involves determining prototype representations based on support samples associated with various classes. Each prototype representation is linked to specific classes, and a dummy prototype representation is established in the same learned metric space. The system classifies query samples based on distance metrics derived from these representations.
Another significant patent is "Multi-task learning for personalized keyword spotting." This patent outlines systems and techniques for personalized keyword spotting through multi-task learning (PK-MTL). The process includes obtaining an audio sample, generating representations of both the keyword and the speaker, and determining a similarity score based on these representations. The keyword spotting output is generated by analyzing the similarity score against a threshold, allowing the system to accept or reject the audio sample as containing a target keyword.
