Abstract

A memory system for speech synthesis employs a set of three memories for specifying the speech data to be applied to a speech synthesis circuit. The speech synthesis circuit is responsive to speech data parameters having a fixed number of bits. The speech data parameters are stored in a first memory 202 at a plurality of selected locations. A second memory 203 contains address data having fewer bits and respectively identifying locations within the first memory where desired speech data parameters are stored. The address data from the second memory is converted into the speech data parameters stored in the first memory as required by the speech synthesis circuit. The address data in the second memory can be formed into data frames having a plurality of data fields, wherein each data field corresponds to one memory location. In a preferred embodiment, these data frames are stored as ordered sets in the second memory with each ordered set of data frames corresponding to a portion of synthesized human speech data parameters are identified for input via register 212 to the speech synthesis circuit by the selection of address data in a third memory (12A, 12B Figure 3 not shown) which corresponds to the desired ordered sets of data frames in the second memory. <IMAGE>
