An often overlooked area of your computer or phone I'm sure is the Accessibility settings. If you don't have any visual or hearing impairments you've really no need to visit this section.
However on WP8.1 there's a goodie lurking there. In Settings, go to Ease of Access and check out "Use Speech To Announce Caller ID".
Enabling this has your phone read out the names of your incoming callers without you having to pick up the phone :)
