Abstract:
An IC card with a built-in voice synthesizing function is provided which includes a solid-state memory containing vector-quantized coded data, a pattern generating means for generating patterns each composed of a prescribed number of digital data by repeatedly performing calculations using a recurrence equation with initial values given by coded data read out of the solid-state memory, a converter circuit for limiting the band of each pattern generated by the pattern generating means and converting into an analog voice signal, and a gain control circuit for adjusting the gain of the analog voice signal output from the converter circuit on the basis of gain data read out of the solid-state memory.
