SPEECH SYNTHESIZER WITH FUNCTION OF DEVELOPING MELODIES

A synthesizer is disclosed which has the function of generating synthesized human voices and melodies in the form of synthesized sounds. The speech synthesizer may be implemented with one or more LSI devices which include a central processor unit for receiving word codes or melody program codes and for controlling the synthesizer, a memory for storing the sequence of synthesis for each word and melody, a synthesized word generator for providing audible indications of the respective words in the form of a synthesized sound and a melody generator for providing melodies in the form of a synthesized sound. A decision circuit decides if word codes or melody programs are provided. The selected words are audibly delivered by fetching its associated sequence of synthesis from the memory and synthesizing those words through the synthesized word generator or the selected melodies are audibly delivered by fetching its associated sequence of synthesis from the memory and synthesizing the selected melodies through the melody generator.
