Latest Patents

Ueno's latest patents include a text generator, text generating method, and computer program product. According to an embodiment, this text generator comprises a recognizer, a selector, and a generation unit. The recognizer is designed to recognize an acquired sound and obtain recognized character strings in recognition units along with confidence levels of these recognized character strings. The selector is responsible for choosing at least one of the recognized character strings for a transcribed sentence based on parameters related to transcription accuracy and the workload required for transcription. The generation unit then generates the transcribed sentence using the selected recognized character strings. Another significant patent involves an apparatus and method for clustering speakers, along with a non-transitory computer-readable medium. This speaker clustering apparatus includes a clustering unit, an extraction unit, and an error detection unit. The clustering unit extracts acoustic features from an acoustic signal and clusters utterances into speakers using these features. The extraction unit acquires character strings representing the contents of the utterances and extracts linguistic features of the speakers. The error detection unit determines if an utterance is erroneously clustered based on the fit of character strings with the linguistic features of the respective speakers.
