We have just released a version of MorphVOX designed to enhance gaming
over audio chat. It is useful for gamers who want to role-play a
character that is of a different gender (or species) than the player.
Since MorphVOX was designed and developed for online games, it has a
number of features that gamers find useful - such as push-to-talk,
sound effects, audio alarms and key mapping. Additional themed voices
are now available for free. Online gamers can now sound like the
character they play, whether they choose to be a mighty giant or a
grumpy dwarf.
I've been using MorphVOX on my latest obsession, GuildWars. Some of my
friends have been using it on World of Warcraft and Dungeons & Dragons
Online.
MorphVOX comes in a freebie Junior version (limited features with ads)
and a full commercial 7-day trial version.
