According to one embodiment, in a speech processing device, an extractor windows a part of the speech signal and extracts a partial waveform. A calculator performs frequency analysis of the partial waveform to calculate a frequency spectrum. An estimator generates an artificial waveform that is a waveform according to an interval between the pitch marks for each harmonic component having a frequency that is a predetermined multiple of a fundamental frequency of the speech signal and estimates harmonic spectral features representing characteristics of the frequency spectrum of the harmonic component from each of the artificial waveforms. A separator separates the partial waveform into a periodic component produced from periodic vocal-fold vibration as an acoustic source and an aperiodic component produced from aperiodic acoustic sources other than the vocal-fold vibration by using the respective harmonic spectral features and the frequency spectrum of the partial waveform.

According to one embodiment, a markup assistance apparatus includes an acquisition unit, a first calculation unit, a detection unit and a presentation unit. The acquisition unit acquires feature amount for respective tags, each of the tags being used to control text-to-speech processing of a markup text. The first calculation unit calculates, for respective character strings, a variance of feature amounts of the tags which are assigned to the character string in a markup text. The detection unit detects first character string assigned first tag having the variance not less than a first threshold value as a first candidate including the tag to be corrected. The presentation unit presents the first candidate.

According to one embodiment, a speech processing apparatus includes a histogram calculation unit, a cumulative frequency calculation unit, and a filter production unit. The histogram calculation unit is configured to calculate a first histogram from a first speech feature extracted from speech data, and to calculate a second histogram from a second speech feature different from the first speech feature. The cumulative frequency calculation unit is configured to calculate a first cumulative frequency by accumulating a frequency of the first histogram, and to calculate a second cumulative frequency by accumulating a frequency of the second histogram. The filter production unit is configured to produce a filter having a characteristic to get the second cumulative frequency near to the first cumulative frequency.
摘要:
A lithium secondary battery of the present invention has a positive electrode is provided with a positive electrode mix layer that includes a positive electrode active material and a conductive material. The positive electrode mix layer has two peaks, large and small, of differential pore volume over a pore size ranging from 0.01 μm to 10 μm in a pore distribution curve measured by a mercury porosimeter. A pore size of the smaller peak B of the differential pore volume is smaller than a pore size of the larger peak A of the differential pore volume.

In a planetary reduction gear device of a starter, a planet carrier forms gear shafts and planetary gears are rotatably supported by the gear shafts through bearings. The planet carrier further forms waste shafts projecting in a direction same as that of the gear shafts. The waste shafts are arranged on a circle having a center coincident with a rotation axis of the clutch outer portion at regular intervals in a circumferential direction. The circle on which the waste shafts are arranged has a diameter different from that of a circle on which the gear shafts are arranged. A speed reduction ratio can be changed by mounting planetary. gears having a gear specification different from that of the planetary gears supported on the gear shafts on the waste shafts. The planet carrier can be integrally formed with a clutch outer portion of a one-way clutch.
摘要:
A business form handling system includes an image reading device for reading a business form and a terminal apparatus installed at the window for discriminatively deciding whether a read image corresponds to a first species of business form by referencing form species identifying definition information stored previously in a file. When the read image corresponds to the first species of business form, the terminal apparatus cuts an image from a field corresponding to a format inherent to the first species of business form to thereby recognize contents of statement from the cut image and executes processing in accordance with result of the recognition. Unless the read image corresponds to the first species of business form, the terminal apparatus decides discriminatively whether the read image corresponds to a second species of business form by referencing the form species identifying definition information. When the correspondence is found, the terminal apparatus cuts an image from a field corresponding to a format inherent to the second species of business form to thereby recognize contents of statement from the cut image.
