The /d/ sound is spelled with <d>, <dd> or <de>, and the /l/ sound is <l> or <ll>. Notice how the homograph do makes pairs with with low and loo.
The contrast is between a voiced stop and a voiced lateral continuant, fairly close together in the mouth. It may be a problem for learners when the sounds are contrasted medially, but not generally in other environments.
The /l/ sound in RP is usually a clear /l/ initially or medially and a dark /l/ when final in the syllable. It may also be syllabic, occurring after another consonant without an intervening vowel. The computer identified many pairs contrasting /d/ with syllabic /l/, as in arrived/arrival. I have removed all of these, since they would not be perceived as minimal, nor would they be a problem for any learners.
The only mildly taboo word pair is peed/peal.
Interesting pairs include:
comedian chameleon
dafter laughter
dental lentil
devil level
dipstick lipstick
humidity humility
meadow mellow
overawed overall
reddish relish
Spaniard spaniel
