摘要:
A database construction apparatus and method which construct a tree structure database are provided. First of all, consecutive node numbers are assigned to nodes for each layer, from an upper layer to a lower layer in a tree structure, in the order of the node numbers of parent nodes. Thereafter, the respective nodes are assigned child node relative numbers representing relative values between the node numbers and the node numbers of corresponding child nodes.

The distance between the first two pitch marks of a voiced portion of speech data to be processed is calculated. The difference between the adjacent inter-pitch-mark distances is calculated. The respective calculation results are stored and managed in a file.
摘要:
A segment set before updating is read, and clustering considering a phoneme environment is performed to it. For each cluster obtained by the clustering, a representative segment of a segment set belonging to the cluster is generated. For each cluster, a segment belonging to the cluster is replaced with the representative segment so as to update the segment set.
摘要:
A device and method for calculating likelihood of an observed feature parameter for a plurality of standard patterns. Coefficients used in an equation for calculating likelihood for each of a plurality of standard patterns are generated and stored in a database. Further, a power of the observed feature parameter is calculated. The likelihood is calculated via a product-sum calculation based on the calculated power and the coefficients corresponding to the powers.
摘要:
The system implements high-accuracy speech recognition while suppressing the amount of data transfer between the client and server. For this purpose, the client compression-encodes speech parameters by a speech processing unit, and sends the compression-encoded speech parameters to the server. The server receives the compression-encoded speech parameters, and speech processing unit makes speech recognition of the compression-encoded speech parameters, and sends information corresponding to the speech recognition result to the client.
摘要:
An anti-fogging coating material is disclosed which comprises a phosphoric acid compound binder; and oxide particles having an average particle diameter of 1 to 300 nm mixed with the phosphoric acid compound binder and provides an anti-fogging coating with a high hydrophilic property and a high water absorption property, capable of retaining the high hydrophilic property for a long period of time.

A wafer processing method which can polish the chamfered portion of a wafer quickly, is disclosed. The processing method comprises the steps of: chamfering a peripheral portion of a wafer obtained by slicing an ingot, by grinding; lapping the wafer; etching the chamfered or lapped wafer; thereafter honing the entirety of the chamfered peripheral portion of the wafer by using a grinding stone while applying a predetermined load to the grinding stone; and thereafter polishing the entirety of the chamfered peripheral portion and the front and rear surfaces of the wafer.
摘要:
In a drainage pump station, a driving machine has a capacity greater than a shaft power necessary for no-discharge operation of a pump, and during severe flooding the pump is operated at an overload exceeding its design capacity. During maintenance operation water is fed from a river on the delivery side of the pump station into the station. When an inflow of rainwater into the pump station is great the pump is operated at the necessary capacity, when it becomes small the water level is kept above a rated value, and when the inflow rate is zero the pump discharge is increased to a capacity at which sediment can be discharged. A suction blower is disposed at the top of a suction sump and interstage valves are disposed in entrances of vertical shafts to effect efficient ventilation of the underground waterway. A feed channel is operated as a pressure channel and the pump is of variable capacity and the water level in the underground waterway is controlled to be constant.
