Integration of computers with the telephone network into commercial equipments has become feasible due to the proliferation of inexpensive Personal Computers and advances in speech processing. Now, Computer Telephony Integration (CTI), helps users to take advantage of new telephony services built-up using speech technologies such as coding, recognition and text-to-speech conversion. This article presents a hardware/software platform based on PC-Compatibles for CTI systems. Hardware comprises boards based on the latest Digital Signal Processors (DSPs) technology, allowing the real-time implementation of fairly complex signal processing algorithms. Software offers CTI application developers an Application Programming Interface (API) to manage and monitor speech processing functions running in the DSPs as well as multiprogramming support for DOS and Windows(R) that permits different CTI applications to be executed on the same or on a different board, each running associated to a phone port.
