Voiceover

Voiceover is a screen reader that was built for the Mac then later it came out for the iPhone 3GS. When It came out for the Mac it started out as a preview on Mac OS X 10.3 Panther, and it was called “Spoken Interface Preview. Then It was brought to Mac OS X 10.4 Tiger and was called voiceover. It was made to be used for people who are blind. When Mac OS X 10.5 Leopard came out, Apple added the Alex voice. It sounded more human and had better quality in speech. The Alex voice also has breathing for example if your reading a long paragraph it will pauz and take a breath before continuing.

After voiceover was successful it was added to the iPod Sshuffle. It helped people control the playback of songs by reading them out the titles. When the 2010 version of the iPod came out, people could have voiceover read out their playlists. Unlike voiceover on Mac OS X where voiceover is retailed as an accessibility feature,, on the Ipod Shuffle voiceover was made to be used by everyone not just the people who are blind.

When the iPhone 3GS was released on July 10th, 2008 Voiceover was added to IOS. In the third generation of the iPod touch the iPod was upgrated to match the hardware of the 3GS. The upgrade also gave it voiceover capabilities. On the IOS platform Voiceover is controlled by using different gestures for example sliding one finger on the screen will have voiceover read out what your finger is passing over. To open the Item the user will double tap on the screen just like how a sighted person will tap once on the screen to open a app or folder. Voiceover can also shut off the screen but, still leave the touch screen active. It is called screen curtain. Its also available on Mac OS X. Under settings you can turn on voiceover by going to general and accessibility then voiceover. You can also press the home button three times or, ask Siri to turn on voiceover.
