I did some preliminary research into this, using my phone, and don't think it would be too hard to implement this as an app.

• ofono provides the phone number of an incoming call as a dbus message. It however doesn't provide the name.
• the contacts contain the details, just some matching necessary, either by accessing the data directly or through some API. (How does the phone UI do it?)
• There are text to speech engines for Linux (like festival)
• If there is a recorded sound file of the name, then its name could be simply added to a field in the contacts database

• for playing the sound: open the stream with property "media.name" = "notiftone"

  Then that stream is classified as non-silent, and it is allowed to play while ringtone is playing. The ringtone volume is attenuated a bit so that headphones aren't too loud. This nonsilent/notiftone stream isn't affected by this, so this should be taken into consideration when figuring out the volume for the stream. To have the stream follow global ringtone volume, have property module-stream-restore.id = "x-meego-ringing-volume" (but again, that is not affected by the attenuation). As a reference, ringtone volume is 77% when headphones are connected, 100% otherwise (-6.81 dB).

Proof of concept probably in a few hours or a weekend. (Not from me though)
