How do I install Voice Banked Voices for Grid 3?

Grid 3 is compatible with any voice in a SAPI5 format, this includes voice banked voices created by third parties. These voices will need to be installed and licenced with Windows first and should then appear in Grid 3 as part of the Voices store. Ensure Grid 3 is closed before starting any installation, to guarantee Grid 3 picks up the new voice successfully. Currently, only SpeakUnique voices are compatible with Grid for iPad.
