Random tone or voice message synthesizer circuit

A message synthesizer circuit comprising:

• compressed message data storing means for storing a plurality of compressed message data, each corresponding to a plurality of message codes;
• ring counter means for emitting a count data by counting rings in synchronism with a predetermined clock signal with the total number of said plurality of compressed message data corresponding to a maximum count number of said ring counter means;
• input means connected to receive an external input message code signal asynchronously with the operation of said ring counter means;
• message code selector means connected to receive the count data from said ring counter means and the external input message code signal from said input means for randomly altering an array of count data emitted from said ring counter means, which corresponds to a specific message code signal, to convert said count data into random message code signal;
• means for reading out the compressed message data corresponding to said random message code signals from a corresponding area of said compressed message data storing means;
• and
• means for decoding said compressed message data read out from said compressed message data storing means and a means for converting said decoded data from digital into analog form to emit a specific synthesized message.
