ABSTRACT:
Speech synthesizer and a computer system having the speech synthesizer operably coupled thereto to provide speech capability for the computer system. The speech synthesizer is capable of electronically synthesizing human speech from coded speech data including parameters as stored either in a solid state memory on a permanent basis or alternatively as temporarily stored in another memory, wherein the coded speech data is made available from an external source, such as a central processing unit of a commercial or home-type computer, as coupled to the speech synthesizer. The speech synthesizer may be in the form of a speech module including a speech synthesizer processor for converting coded speech data into digital speech signals in combination with a mode selector which selectively applies either the coded speech data from a read-only-memory within the speech module or the coded speech data obtained from the external source to the speech synthesizer processor in response to a control signal provided by the external source for determining which of the two alternative operating modes will be employed in a given instance. The computer system is provided with speech capability by including the speech module as a component thereof in combination with a computer input device, the central processing unit of the computer, and an audio amplifier and speaker connected to a digital-to-analog converter of the speech module so as to generate audible human speech from the digital speech signals provided by the speech synthesizer processor of the speech module.
