In all cases, the American English diphthongs are somewhat longer than the simple vowels.

This maybe credited to the fact that General American English has no central diphthongs while Received Pronunciation has /Iq/ and /Eu/. General American English has a combination of /Ir/: learn /lIrn/; /Fr/ lair (барлога); /ur/ lure (спокуса).

In addition General American English doesn't have phoneme /P/. Whenever Received Pronunciation has this sound General American English has either /Q/ or /O/, e.g. clock /Q/, Washington /Q/. Correspondingly to /P/ (R.P.) General American English has /Q/ especially in the Middle West and neighbouring Canada. Before such consonants as l, m, n and before stops AmE have /Q/: top, rob, bomb, don. But before g in the words dog, fog /O/, before /N/ they have /O/ as well.
