Kbase Article of the Week: Enabling Spoken Menus on iPod nano »

Apple Support:

iPod nano (5th generation) and iPod nano (4th generation) include the ability to speak the name of selected menus in iPod software using the text-to-speech capability built into or installed into Mac OS X or Windows.

Note: Spoken menus may not be available for all menu items or synced content. Spoken menus will be generated in the language of the system voice that users have installed and configured on their computer. Some voices may not support this feature. Overall sync times will increase when spoken menus are enabled in iTunes. Audio clips for spoken menus will reduce the available capacity for audio and video content on iPod nano.
