Hello Susenbach,
It would seem that Voiceover has been enabled on your iPod Nano. The following article contains information regarding Voiceover, and how to disable it once it's been enabled.
iPod nano (6th generation and later): How to use VoiceOver
http://support.apple.com/kb/HT4317
From the Home Screen, swipe right or left with two fingers until you see or hear "Page 2 of 2" on iPod nano (7th generation) or "Settings" on iPod (6th generation).
If the icons have been rearranged, or if there are more than four Home screens, you may hear something different.
- Slide one finger around the screen until you hear Settings.
- Double-tap to open Settings.
- Slide your finger up or down the screen until you see or hear General, then double- tap.
- Slide your finger up or down the screen until you see or hear Accessibility, then double-tap.
- Slide your finger up or down the screen until you see or hear VoiceOver, then double-tap.
- Double-tap when you hear "VoiceOver switch button on."
- You'll hear "VoiceOver off" to confirm the setting. Now you can use standard gestures to control iPod nano.
Note: You can also turn off VoiceOver by resetting your iPod.
Cheers,
Allen
