This includes large, easy to read scientific buttons, accessed on a scrolling panel. All the features of the iPad version are included in the smaller design. Customizable for each level of vision: -------------------------------------------- Normal to low vision: Large, clear buttons with optional speech. Low vision: High contrast display mode, with optional speech. No vision / blind: VoiceOver reads the button names before they are activated. The calculation results are spoken. Entry and display on refreshable Braille devices. Why record new voices? -------------------------------------------- Having your iPad, iPhone or iPod Touch talk with your own voice, or that of a friend or tutor will make the calculator sound more natural to you. The calculator will speak with the accent you are used to hearing. Note also that the VoiceOver feature built into your device, while awesome, is not good at reading out large and small numbers. How good is the sound quality of recorded voices? Excellent: The microphone in your iPad / iPhone or iPod Touch 4G is of very good quality, and this calculator performs digital signal processing to ensure the audio level is consistent across all recorded words. Note: Earlier versions of the iPod Touch require an external microphone for recording. The current model iPod Touch and all iPhones and iPads have a built in mic.
