Using TTS (Text to Speech) in C + + Builder

Start BCB, open the menu item Project->import Type Library ..., click Add in the Pop-up dialog box, select Vtxtauto.tlb under Windows\speech directory, and join Vtxtauto[version 1.0] One item. Clicking OK,BCB automatically generates a vtxtauto_tlb.cpp file. This file contains the COM class interface of the TTS engine, which can be used to communicate with DLL files. Create a new project to include this file in:

The source code is as follows:

//unit.h


#ifndef unit1h


#define UNIT1H
