Windows Mobile phones have evolved from passive one-to-one communication device to powerful hand held computing device. Today most new mobile phones are capable of capturing images, recording video, and browsing internet and do much more. Exciting new social applications are emerging on mobile landscape, like, business card readers, sing detectors and translators. These applications help people quickly gather the information in digital format and interpret them without the need of carrying laptops or tablet PCs. However with all these advancements we find very few open source software available for mobile phones. For instance currently there are many open source OCR engines for desktop platform but, to our knowledge, none are available on mobile platform. Keeping this in perspective we propose a complete text detection and recognition system with speech synthesis ability, using existing desktop technology. In this work we developed a complete OCR framework with subsystems from open source desktop community. This includes a popular open source OCR engine named Tesseract for text detection & recognition and Flite speech synthesis module, for adding text-to speech ability.

Mobile and compact devices become more and more popular in our society. Each of us faces with them every day. Certainly each of us has mobile phone, hand-held computers or other hi-tech devices. All of these devices have different mobile platforms. There are such known platforms as Windows Mobile, iPhone, BlackBerry, Symbian OS, Android etc. All of them have different history and advantages and failings.

Such platforms as Windows Mobile, BlackBerry, and iPhone are «closed» enough and limited by either their own devices (BlackBerry, iPhone) or development complexity. Among other problems of above mentioned platforms there is limited API. Even Java platform for mobile devices has some failings such as great number of limitations; very different APIs; device dependent code. Symbian and Windows Mobile platforms are better from this point as far as they support wider range of devices and their APIs give more options. Common problem here is also that there are a lot of platforms. Talking about Open Source and Cross-Platform solutions we should say that they are still developing at the moment and are not widespread yet.

Purpose of Mobile framework:

The purpose of a mobile framework is to utilize a standards-based architecture that leverages existing IT infrastructure and maximizes return on investment. Such a framework is relatively easily deployed and extends enterprise content to mobile users with both good quality and user experience. The purpose of a mobile framework is somewhat different from actual mobile development tools, which are specifically used to develop mobile applications. Mobile frameworks extend existing applications (such as Customer Resource Management (CRM) to mobile workforces and their devices. Just make sure the mobile framework is truly a mobile framework.
