Patent US 5,111,505

A voice synthesizing device which compiles wave segments, such as pitch wave segments, in order to synthesize speech. Speech is synthesized by connecting wave segments to form a contiguous waveform. Each wave segment is assigned one or more connection types which describe the connection to be made between points on that wave segment and points on adjacent wave segments. A wave segment connector uses information on the connection types of adjacent wave segments to connect the end point and lead point of the adjacent wave segments using a normal sampling period or a normal sampling period compressed or expanded by 1/2 of the sampling period. The period used depends on the connection type stored in the connection type memory.
