{ SBTS.PAS -- Sound Blaster Text To Speech Interface for Turbo Pascal 6.0 }
Unit SBTS;
Interface
{$IFNDEF VER60 }
** Needs Version 6.0 of Turbo Pascal to compile **
{$ENDIF }
{ SBTS.PAS
This unit provides an interface to the SBTALKER (TM) Text-to-Speech
driver.
USAGE NOTES:
1. Make sure you have made SBTALKER resident, prior to running your
application. Call from the DOS command line:
SBTALKER /DBLASTER
SBTALKER.EXE and BLASTER.DRV are found on the diskettes that
came with the Sound Blaster.
2. Due to the fact that this unit relies on the built-in assembler,
you'll need Turbo Pascal, version 6.0 or later to recompile.
3. IMPORTANT: Don't attempt to run an application within the
Turbo Pascal Integrated Development Environment. Do not launch
it inside a software-debugger either! It'll HANG your system.
RUN it from the DOS command line.
