At CES, if you don't have a 16,000-square-foot booth like Microsoft, how do you get heard? With so much big stuff at the show, as our columnist Brier Dudley points out, here are a few of the smaller things Seattle-area companies want you to know about:

-- Bellevue-based VoiceBox announced today a joint venture with Nuance Communications to develop advanced voice navigation applications for the personal device, automotive and mobile phone markets. The goal is to develop and deliver something so accurate and intuitive that it further enhances the way people use navigation devices.

-- Seattle-based Volantis, which helps media content be delivered to mobile phones, said today that it launched Volantis Content Services. The service offers a tier of offerings that lowers the cost for content providers wanting to quickly launch a mobile presence.

In addition, Volantis said it was launching a more agressive push into the mobile advertising market by partnering with Bango, a mobile payment platform, and Third Screen Media, a mobile advertising software and services, to provide mobile billing and advertising capabilities.

-- Seattle-based RealNetworks made a series of announcements yesterday.
It said it has integrated its Rhapsody digital music services into the TiVo service to give TiVo subscribers access to more than 3 million songs on demand right from the TiVo remote. The service will be available starting later this year.

RealNetworks also announced a collaboration with Reigncom, which makes the popular iriver portable multimedia devices. Reigncom will bring two new Rhapsody portable players to market. The MP3 players will come Wi-Fi enabled and will allow consumers to download their favorite music over the air directly to the device. Both devices are expected to ship in the U.S. in the first half of this year.
