  • Patent number: 11770213
    Abstract: According to one embodiment, a failure detection apparatus includes processing circuitry. The processing circuitry acquires a time-series signal generated by a sensor module, generates an analysis result including information concerning saturation of the time-series signal by analyzing the time-series signal, and determine a failure of the sensor module based on the analysis result.

  • Patent number: 8223374
    Abstract: A maintenance system of an image forming apparatus is composed of an image forming apparatus and a central management apparatus connected to it via a communication line. The image forming apparatus is composed of an image forming unit for forming an image, an information output unit for outputting intra-machine information of the image forming unit, a voice information input unit for inputting voice information of a user of the image forming unit, and a first communication controller for outputting the intra-machine information and voice information via the communication line.

  • Patent number: 7809554
    Abstract: An apparatus, method, and medium for detecting a voiced sound and an unvoiced sound. The apparatus includes a blocking unit for dividing an input signal into block units; a parameter calculator for calculating a first parameter to determine the voiced sound and a second parameter to determine the unvoiced sound by using a slope and spectral flatness measure (SFM) of a mel-scaled filter bank spectrum of an input signal existing in a block; and a determiner for determining a voiced sound zone and an unvoiced sound zone in the block by comparing the first and second parameters to predetermined threshold values.

  • Publication number: 20100250246
    Abstract: A speech signal evaluation apparatus includes: an acquisition unit that acquires, as a first frame, a speech signal of a specified length from speech signals; a first detection unit that detects, on the basis of a speech condition, whether the first frame is voiced or unvoiced; a variation calculation unit that, when the first frame is unvoiced, calculates a variation in a spectrum associated with the first frame on the basis of a spectrum of the first frame and a spectrum of a second frame that is unvoiced and precedes the first frame in time; and a second detection unit that detects, on the basis of a non-stationary condition based on the variation in spectrum, whether the variation of the first frame satisfies the non-stationary condition.

  • Publication number: 20090030693
    Abstract: In one embodiment, a method for providing voice quality assurance is provided. The method determines voice information for an end point in a voice communication system. The voice information may be from an ingress microphone. The method determines if the voice quality is considered degraded based on an analysis of the voice information. For example, the voice information may indicate that it is distorted, too loud, too soft, is subject to an external noise, etc. Feedback information is determined if the voice quality is considered degraded where the feedback information designed to improve voice quality at an ingress point for a user speaking. The feedback information is then outputted at the end point to the user using the end point.
