How do I repair talking mechanism?

Go into your settings, go to general, scroll down and click on Assessability, then from their you should see a tab that says "VoiceOver" turn it off

Hi your problem to your cellphone is Ear piece if you not hear the ringtone and voice to your talking. you need to repair a hardware and replace the earpiece.thanks :)

Take it to a local jeweler/watch repair and have them check the battery. They should have a tester to test to see if its the battery. If thats not it, you need to check with the retailer you bought it from to get a replacement watch. I am sure it is under some kind of warranty. Best wishes.

When you talk on you phone make sure your volume label is up. There is a key in right hand site on top. Press up / down for adjusting the volume. if you seen the volume label is fully up but nothing to be change in voice, its mean the internal speaker is damaged. Replace it. And about your voice is not loud from other side then replace that microphone also. I think that's a common problem of Nokia N73 mobiles.
Thanks

It is 100% the mike. it needs to be replaced.

Let it dry out good!
I'd put it in my car on the floor with the heat on highest and the windows open as needed!

The mouth piece of your phone is bad, tale it to a technician and make them repair or replace the microphone in the mouth piece.

you need to replace the voice coil. it is already grounded, that is the one inside the mic ball (where you speak or sing). it is not repairable so you need to purchase a new voice coil

Check in preferences > Change Voice to make sure that a voice is selected. If it is, it probably corrupted. Pick a new voice. If none of the other voices work, plug your TomTom into your computer and boot up TomTom HOME and reinstall the voices. If after that they still don't work, contact TomTom support and ask them for advice. They will probably have you send it in for repair on broken speakers.

Please rate, Thank you!
