Hello & Welcome,
I'm Greg and will do my best to assist you today.
Sorry to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) The FULL Model Number of the phone system you are working with? If this is a cordless system, that model should be printed on a sticker on the bottom or back of the MAIN base and START with KX-TG.
2) How many TOTAL cordless handsets do you have with this system?
3) Are you referring to the feature where the system "speaks" the caller's information?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
If you are referring to the "Talking Caller ID", here is a video that shows how to turn this feature off for may Panasonic systems.

NOTE: The handset shown in the video may not match yours exactly, but the steps will be the same.
If this has answered your question(s), please take a moment to rate MY service level (5-star is my goal) so that I get credit for my time helping you with this question.
You should see some "stars" to do that, but please let me know if you do NOT see them (you may have to scroll UP or DOWN) or can not use them.
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
