New Resound Nexia 9 and poor calling voice using an Iphone 14plus

While using my iphone 14+ connected to my new Resound Nexia 9 ( not MRIE), my recipients are complaining that my voice is echoy and the first syllable of some words are being chopped off. I remember reading about this in the forum but all search pulls up is this problem with the MRIE Nexia version. I saw my HA Professional today and he made some changes having to do with “voice isolation”.??? But it did not solve the problem. If you know of the problem or remember the discussion please add some info.
