内容記述 | Recent development of information processing networks requires the further expansion of the function of audio response unit(ARU) to increase response vocabulary and number of multiplex channel.The audio response unit reported in the paper meets these requirements by the principle of speech synthesis of combined sum of acoustical elements which are damped sinusoidal waves for voiced sounds and bandpassed noises for unvoiced sounds.These elements are pre-recorded on core memory because the memory capacity needs less than 40k bits only.The control data for speech synthesis are also less than 3 200bit/sec and a magnetic drum of 512 tracks and 2MHz clock can store more than 2 000 words of 0.8 sec duration with 20m sec or less maximum access time.Digital store of acoustical elements on core memory and relatively simple processing of speech synthesis enables multiplexing operation by time devision and the possible number of multiplex channel is 40 under the conditions described in the paper.In many case response messages have several pre-determined formats accordingly only the assignment codes for message format and variable words in the message are transmitted from CPU to ARU and one telephone line of capacity no more than 120 Baud can transmit all necessary codes for multiplex operation of 40 channels. | |||||||
