Lance" Subject: Re: American Diphthongs In recordings of Missourians of German descent, I found [ao] to be the diphthong used by those who had maintained several other German- influenced features such as retracted [a]. Of course, they hadn't retracted the [a] but simply used the sound of the German long a. Once you start noticing [ao] you'll hear it frequently. DMLance
