- LANtastic(TM) Voice Programmer's Interface(TM)
-
- Make your software laugh, sob, growl, warble, wail, sing and talk
- with the LANtastic Voice(TM) Adapter and the LANtastic Voice
- Programmer's Interface (VPI(TM)).
-
- When used in conjunction with the LANtastic Voice Adapter (sold
- separately), LANtastic VPI makes adding sound and speech to your
- software easy. Using a set of simple, straight-forward commands,
- you can create educational and training programs on disk or CD-ROM
- that actually give verbal instructions to students. You can develop
- voice mail, "talking" software demos, music synthesis, sound
- effects and much more. Using the tape in and out jacks on the Voice
- Adapter, you can record from a CD player, tape recorder, microphone
- or other external sound source, then play back later through an
- amplifier with speakers.
-
- The LANtastic VPI is a set of routines for interfacing to the
- LANtastic Voice Adapter. VPI uses a structure called the Voice
- Command Block (VCB). This block is similar to an NCB or MCB in the
- NETBIOS. It contains pointers to blocks of data which can be used
- for PLAY and RECORD. Commands can be no-wait which means control
- returns to the calling program immediately while the VPI works in
- the background. When the VPI command completes, the user's POST
- routine is called.
-
- The Artisoft LANtastic Voice Adapter is a low-cost, IBM compatible
- expansion device which converts between audio/voice signals and a
- digital data stream. When used in conjunction with supporting
- software, it provides the capability to digitize spoken messages,
- preserving them in nearly their original fidelity.
-
- LANtastic VPI is sold to developers directly through Artisoft. For
- more information, call 602-293-6363.
