    摘要： The speech decoding apparatus decodes a speech signal that is coded into a plurality of speech parameters including an excitation parameter, using the excitation parameter. The controller controls an output speech volume of the decoded speech signal according to a predetermined gain parameter. At this point, the gain parameter is corrected according to an energy of the speech signal corresponding to the excitation parameter. The controller controls the output speech volume corresponding to the gain parameter only when the energy of the speech signal corresponding to the excitation parameter is within a predetermined range.

    摘要： In a communication between transmitter-side and receiver-side communication control devices, when a data communication is desired after a facsimile communication without opening a telephone line, the transmitter-side communication control device transmits a data communication shift request signal to the receiver-side communication control device based on a previous command inputted to the transmitter-side communication control device. In response to this request signal, the receiver-side communication control device switches a communication mode from a facsimile communication mode to a data communication mode, and then sends back a data communication shift acknowledge signal to the transmitter-side communication control device. In response to this acknowledge signal, the transmitter-side communication control device switches a communication mode from a facsimile communication mode to a data communication mode. Accordingly, the data communication can be performed automatically after the facsimile communication without once opening the line. Such a data communication after the facsimile communication may also be realized based on a data communication shift request signal from the receiver-side communication control device.

    摘要： The speech coding apparatus comprises a memory to store the convolution data of a pitch reproduced excitation pulse sequence extracted from an excitation pulse sequence in the pitch reproduction processing with a coefficient of linear predictive synthesis filter. When the convolution processing is repeated again, the speech apparatus performs the memory control to write a part of the previous convolution data in a storing area of current convolution data, then performs the pitch prediction processing using the current convolution data.

    摘要： A method for managing a defect in an optical disk employed in a recording/reproducing apparatus. The optical disk includes a data area and a preliminary area. Further, the data area includes sectors for storing data and the preliminary area includes alternate sectors for defective sectors occurring after initialization of the optical disk. In the optical disk, physical addresses are assigned to all of the sectors of the data area and the preliminary area in an ascending order. In contrast, logical addresses are assigned to the sectors in an ascending order skipping the defective sectors detected at the time of the initialization and the sectors of the preliminary area. The method for managing a defect in an optical disk comprises the steps of constructing a table in which a cumulative number of defective sectors detected at the time of the initialization of the optical disk and being present between a starting physical address of the optical disk and a sector subsequent to a defective sector is used as the logical address of the sector subsequent to the defective sector and of converting the logical address of a sector into the physical address thereof by using the table. Thereby even when a defective sector occurs in the optical disk, the logical address of a sector can easily be converted into the physical address thereof.
