    Default Thirty

    I pronounce the word "thirty"; THERDEE. I would like to know what other words have that distintive sound where the T is replaced by a D when pronounced. I also pronounce "british; BRID-DISH.
    thanks for replying.

    The t sound in thirty in BrE is very clear and distinct.
    In AmE it's somewhere between t and d sounds. The t sounds will sound somewhat muddled, much less clear than typical British t.
    Same thing applies to your word British.
    The rule of thumb is that t is pronounced as d if it's not proceeded by a voiceless consonant: /s/f/k/p/ or by /ch/sh/th/.

    In some dialects of BrE, most notably Cockney, the -t becomes a glottal stop-- thir'y- otherwise it is generally a fairly clear sound.

    BTW, Tdol, is it really true that certain Cockney words are spelled backwards?
    I heard that "old" can sound something like "di:lou".

    I guess Tdol will not have an answer for me...

    "t" isn't replaced by the sound [d]. "t" is [d].

    When "t" is surrounded by voiced sounds (sounds that are made by vibrating the vocal folds: [r] and [y]), "t" also vibrates, and when it does, it becomes [d]. It's a phonetic process, and it's related to physical factors: it's easier to keep the stream of air vibrating than it is to stop vibrating for "t" and then start vibrating for "y".

    pity => pi[t]y and pi[d]y
    Marty => Mar[t]y and Mar[d]y
