Title: Voice analyzing and synthesizing device
Inventor: ISHIKAWA TAKAYUKI
IPC: G10L19/04
Filed: 1990-08-21
Abstract: PURPOSE:To reproduce a sound of high quality which is invariably stable and good in articulation by transmitting all basic analytic frames that a transmission frame contains with variable length frames represented by several representative analytic frames. CONSTITUTION:A power extractor 112 and a pitch extractor 108 extract short- time means voice electric power and pitch information from a quantized voice signal in basic analytic frame units and supply those voice electric power and pitch information to a multiplexer 111. The multiplexer 111 quantizes data regarding the number of offered representative frames, frame numbers, voiceless section numbers, LPC coefficients, the voice electric power, and pitch information, properly combines them into multiplexed data, and sends it to a multiplexing side 2 through a transmission line 3. In this case, 20 basic analytic frames, for example, are represented by 3, 5 or 6 representative frames for each transmission frame and sent out to the multiplexing side 2 by variable length frame composition. Consequently, a synthesized voice of high quality is obtained.

The black liquor concentrated in the chamber 42 is fed into the chamber 43 through a communicating line 50, is further concentrated, and is taken out through a line 51. In this case, since the liquor can be passed at a concentration near the solubility limit of an Na compound, both the quantity of a liquid evaporated and the quantity of the liquor supplied are extremely small as compared with the quantity of the liquor circulated, so that the mixed liquid is circulated at a concentration lower than a predetermined value. Accordingly, the Na compound separates out in the lines 44, 45 and the pump 48.
