probably because they didnt start out at profound losses and later lost more but learned speech when they had better hearing. Tyler can't decipher the sounds because he doesn't knwo what they all mean ...yet and I don't think its impossible either
I'm sure he will speak sooner or later just on his own time...
Since I didn't lose my hearing til later I am oral and my speech is perfect ppl don't believe me when I say I'm deaf until they see my zebra print hearing aids. I prob know one of the 2 you are speaking of as she is one of my good friends and I know she's worked hard to get her speech where it's at...its esp hard if you can't hear yourself speak or you don't know what the sound is supposed to sound like and mimic that sound if you've never heard it
