Abstract: Apparatus for use by a broker including a memory for holding a number of market prices each corresponding to a security or a commodity. A speech synthesizer provides that prices may be quoted to customers in a synthesized human voice. A telephone interface connects outside calls to a DTMF transceiver which is in turn connected to a programmed microprocessor unit so that a caller may key in instructions or information. Instructions for price quotations result in the price for the selected security or commodity being reported to the caller in a synthesized human voice. The apparatus is also capable of monitoring price triggers and reporting violations of price triggers by calling a predetermined telephone number and reporting the violation in a synthesized human voice. Also, price requests are logged and the unit is responsive to an instruction keyed in by a broker through his telephone to report the contents of the log over the telephone in a synthesized human voice.
