SPEECH CONTROL FOR VIRTUAL INSTRUMENTS USING THE TMS320C30 DSP

This application report describes a speech recognition interface for a Microsoft Visual Basic (VB) application. The VB application is a virtual instrument control system that can be used in various environments. The speech recognition interface enhances the ability of the operator to control various system components without manually navigating the graphical user interface (GUI) screens of the VB application.

Several options were considered during the analysis but only one option proved to be optimal. The solution described in this paper uses the Texas Instruments (TI(TM)) TMS32C30 DSP to handle all speech recognition calculations.

The speech recognition component using the TI TMS320C30 DSP was implemented as a co-processor residing on the PC. The VB control system runs on the main PC processor. The controlled instruments are attached to the system through an IEEE 488 parallel bus.

This report includes a system level diagram and references.
