Company has agreed to buy MobileVoiceControl, which lets cell-phone users dictate and send e-mails and texts Nuance Communications will acquire MobileVoiceControl Inc., which provides a service that lets cell-phone users find and download information without pressing so many keys.Nuance has agreed to acquire MobileVoiceControl, a privately held provider of a service that lets cell-phone users dictate and send e-mail and text messages, search the Web, create calendar entries and call their contacts through speech recognition. They only have to press one key on the phone to get started, according to the companies.Although typing words with a numeric keypad is routine in some parts of the world and among younger cell-phone users, many people find it hard to do. This factor, plus the need to look at the phone and navigate a multilevel hierarchy to find all the features and content on it, may be holding back full use of new handsets and services. Carriers are starting to embrace speech recognition as a way around this barrier. Sprint Nextel Corp. already offers the MobileVoiceControl service on some devices, and users can also download it from Handango Inc. MobileVoiceControl offers versions for selected Microsoft Corp. Windows Mobile, Palm Inc. PalmOS and Research In Motion Ltd. BlackBerry devices. It requires a monthly subscription fee. Gannett Co. provides news, sports, weather and other information, along with ads, from its USA Today newspaper on the MobileVoiceControl service.Nuance, in Burlington, Massachusetts, is the maker of Dragon Naturally Speaking 9 software for PCs and a major vendor of core speech-recognition technology. It supplies that core technology to providers of mobile speech-enabled products, including V-Enable Inc., and will continue to do so, said Nuance spokeswoman Kristen Wylie. Nuance also has its own mobile system, called Nuance Mobile, in beta testing. By combining its underlying technology with the work MobileVoiceControl has already done, the company can build a complete service that is better at recognizing what end users say, Wylie said.MobileVoiceControl’s employees will join Nuance but remain in the company’s hometown of Mason, Ohio, Wylie said. The companies did not disclose the financial terms of the agreement, which is expected to close by the end of the month. Technology IndustrySoftware DevelopmentSmall and Medium Business
