Here's a reading of Keats' "Ode to a Nightingale" in a reconstruction of early 19th century London pronunciation.
The historical mid-vowels are still undiphthongized. Rhoticity has been lost. The BATH vowel is in full swing, the PRICE and MOUTH diphthongs do not have their modern-sounding onsets yet. Unaccented final <-ing> is [ɪn], and some historical weak forms of words like "my" survive.
