Nemonika Browser 1.1 offers you a speech processing system which provides real-time speech recognition as well as synthesis.

Major Features:

1. The speech recognition engine provides a small command oriented vocabulary, perfect for navigation and for implementing a "voice typewriter" that allows you to enter an arbitrary string.
2. The speech synthesizer can provide navigation feedback and can directly speak content such as web pages or text files.
3. Web pages are simultaneously rendered to fit onto a small screen to allow for simpler reading, navigation and scrolling.
4. Nemonika currently has support only for US English.
   

Key Benefits:

• Faster Input
• • You can choose at any time to enter data or commands either via speech, the soft input panel(SIP), touch screen or thumb pad. When using the SIP you receive immediate audio feedback allowing you to type more quickly.
• Performance
• • Nemonika is very responsive, everything is done on the client side. Server based solutions need to upload raw audio data to a server which then processes it and returns it as text to your mobile.
    
• Automatically Reformatted for Smaller Screen
• • The web is not ideal for viewing on small screens. Nor is it ideal for when you are away from a desktop in settings where you may need to multi-task your vision. Nemonika is not a desktop browser, it's a browser for the road. The one inside your head you're speeding down all the time.

Requirements:

• Windows Mobile 5.0 and above.
