Use Neospeech with TTS plug-in

we purchased neo speech text to speech engine, looking for integration with gateway. Neospeech comes with it’s own text to speech engine. I would like to know how to apply plugins.

That should be easy.

Install the Neospeech software, reboot. Open Voicent Gateway, select Setup > Options > text-to-speech, then select the voice provided by Neospeech.
