  • Publication number: 20220014628
    Abstract: The example embodiments provides a processing system (10) including: an acquisition unit (11) that acquires target speech data in which a target speech is recorded or a target feature value that indicates a feature of the target speech; an inference unit (12) that infers a language of the target speech, based on an inference model for inferring a language of a speech from speech data or a speech feature value and the target speech data or the target feature value; a result output unit (13) that outputs an inference result by the inference unit (12); a determination unit (14) that determines whether the inference result is correct; and a learning data output unit (15) that outputs the inference result determined to be correct by the determination unit (14) and the target speech data or the target feature value, as learning data for generating the inference model.

  • Patent number: 10347273
    Abstract: A speech processing apparatus includes: an expectation value calculation unit configured to calculate, using an input signal spectrum and a speech model that models a feature quantity of speech, a spectrum expectation value which is an expectation value of a spectrum of an acoustic component included in the input signal spectrum; and an acoustic power estimation unit configured to estimate an acoustic power of the acoustic component of the input signal spectrum based on the input signal spectrum and the spectrum expectation value.

  • Publication number: 20170364854
    Abstract: The purpose of the present invention is to provide a technology which is capable of appropriately evaluating a person's conduct with respect to another person. Provided is an information processing device, comprising a recognition unit 11, a detection unit 12, and an evaluation unit 13. The recognition unit 11 recognizes an evaluation subject's conduct. The detection unit 12 detects a trigger which is a state of a person other than the evaluation subject which triggers the evaluation subject's conduct. Using the detected trigger and the result of recognition by the recognition unit 13 relating to the evaluation subject's conduct, the evaluation unit 13 evaluates the evaluation subject's conduct.
