Predictive Text Capability

CAMBRIDGE, UNITED KINGDOM and CALGARY, ALBERTA--(CCNMatthews - March 29,
2005) -

eZiText® technology to be integrated into TTPCom's Ajar application
platform for worldwide markets

Zi Corporation (TSX:ZIC)(NASDAQ:ZICA), a leading provider of intelligent
interface solutions and TTPCom Limited ('TTPCom') - a subsidiary of TTP
Communications plc (LSE:TTC), jointly announce a collaboration to
integrate Zi's eZiText® predictive text input technology into TTPCom's
Ajar application platform. The pre-integration of the technology is
designed to address the needs of the fast-growing Asian marketplace and
will be available in Third Quarter 2005.

"Working with a world leading company such as TTPCom reaffirms the key
role that Zi's technology has established in the global marketplace and
in particular Asia," commented Glen Morgan, senior vice president of
global sales and marketing for Zi Corporation. "OEMs are demanding more
and more platform solutions with pre-integrated application frameworks
to ensure faster time to market for their products. TTPCom's Ajar
applications platform, pre-integrated with Zi's predictive text input
technology is a major step forward in helping OEMs achieve this goal."

"Manufacturers are under intense pressure to deliver differentiated
handsets with increasing levels of functionality," said Morten Iversen,
TTPCom's strategic alliances manager. "Consumers expect capabilities
such as predictive texting to be offered as standard, but the inclusion
of each new function requires extensive testing and specialist
engineering resource. By working with Zi to embed the company's
innovative predictive text input technology into Ajar, we are enabling
our customers to deploy the technology quickly and cost effectively."
