Pronexus provides a Voice Card Simulator that simulates the actions of a real voice card in software, using the keyboard and speakers of your computer. The simulator is intended mainly for testing and demonstrations and requires that a sound card be installed.
Enable the Voice Card Simulator via the VBVoice.ini file:
[Voicecard]
Type=Simulator
NOTE: Speech recognition applications may be used with VBVoice running on the sound card, by using either the card simulator or VBVoice test mode. This becomes very useful when making product demonstrations on a laptop, without any telephony hardware. In such configuration, the recognition results highly depend on the quality and the directional characteristics of the microphone!
