Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005. / Automatic speech recognition (ASR) systems are an attractive means for companies to deliver value added
services with which to improve customer satisfaction. Such ASR systems require a telephony interface to
connect the speech recognition application to the telephone system. Commercially available telephony
interfaces are usually operating system specific, and therefore hardware device driver issues complicate the
development of software applications for different platforms that require telephony access. The drivers and
application programming interface (API) for telephony interfaces are often available only for the Microsoft
Windows operating systems. This poses a problem, as many of the software tools used for speech recognition
research and development operate only on Linux-based computers. These interfaces are also typically in
PCI/ISA card format, which hinders physical portability of the device to another computer. A simple, cheaper
and easier to use USB telephony interface device, offering cross-platform portability, was developed and
presented, together with the necessary API.
