Zi’s New eZiType Technology Brings Word Completion and Typing Correction Features to Sony Ericsson Mobile Phone and E-mail Device

Calgary, AB, Canada, March 27, 2006 - Zi Corporation (Nasdaq: ZICA) (TSX: ZIC), a leading provider of intelligent interface solutions, today announced that Sony Ericsson has embedded Zi’s eZiType™ product on its new M600 mobile phone and e-mail device. Zi’s technology will empower M600 users with prediction and auto-correction capabilities for its keyboard use improving the users’ overall input experience with the new device.

Launched in February 2006, the Sony Ericsson M600 is a powerful, fully-specified e-mail tool and mobile phone with a slim design feature and a touch screen. The M600 is the second Symbian OS 9.1 and UIQ 3.0 enabled phone in the Sony Ericsson portfolio, providing users with the ability to customize the device. Zi’s typing correction and word completion technology enable users to take full advantage of the M600’s dual function keyboard for sending e-mails or text messages.

“By combining Zi Corporation’s innovative word prediction and auto-correction features with the ergonomic design of the M600, text messages, e-mail messages and the overall text input becomes a more intuitive and enjoyable process for all users.” said Brendan Press, Head of Enterprise Marketing, Sony Ericsson.

“With industry analysts predicting explosive growth in the mobile e-mail market, the small keyboard-based interface of most devices will present a number of challenges for new users,” said Zi Corporation’s Chief Technology Officer and Chief Operating Officer Milos Djokovic. “eZiType empowers users with full-word prediction and auto-correction technologies, enhancing the overall user experience with any mobile e-mail device. As one of the first manufacturers to embed eZiType into its mobile e-mail device line-up, Sony Ericsson is enabling M600 users to compose words more quickly and therefore send more messages.”
