To provide a sequencer capable of outputting voice, in which operations such as addition and change of each language expression is facilitated, while the language expression can be performed with a plurality of languages.

In the lower left side of a CPU 60, a memory device 50, an external input device 10, and a country name selecting means 70 including a plurality of depression button switches for language designation, are connected. In the lower right side of the CPU, a speech synthesis LSI 80, and a memory 90 for speech signals, which is exclusively provided to the LSI, are connected. The speech synthesis LSI reads data for speech signals in the memory for speech signals present in a specific address, in response to an instruction from the CPU, and outputs the speech signal from a speaker SP. The memory device 50 includes a sequence program area 50c that includes a series of sequence programs for instructing ladder arithmetic operation and a support program for supporting new creation and editing of the program, and a speech data storage area 50d.
