Choledocholithiasis

Break it into four parts: /ˌkoʊlɪˌdoʊkoʊlɪˈðaɪəsɪs/. Emphasize the -lith- in -lithiasis with secondary stress on -di- within choledo- and primary stress on the -lith- syllable? Actually: the primary stress falls on the -li- of lithiasis: chole-docho-li-THI-a-sis? Wait, the canonical pronunciation is /ˌkoʊ.ləˌdɒk.ə.lɪˈðaɪ.əs.ɪs/ in UK and /ˌkoʊ.ləˌdɒk.oʊ.lɪˈðaɪ.ə.sɪs/ in US. In plain terms: co-LE-do-CHO-li-THI-a-sis; ensure you land on the -THI- for -lithiasis-, with the dy- sound as in dice. Audio reference: consult medical pronunciation resources or a clinical dictionary with audio to model the stress pattern and syllable boundaries. Mastery tip: slow, then speed up while keeping the -li- and -thy- segments crisp.

Common errors include misplacing the stress, e.g., saying cho-LE-do-... instead of co-LE-do-; mispronouncing lithiasis as lith-AY-si-s or li-THA-sis; dropping syllables, turning it into chole-docho-lithiasis or docholithiasis. Correct by segmenting: choledocho-li-thi-a-sis, with stress on li- in lithiasis and clear articulation of -do- and -cho-. Practice saying it slowly: ko-leh-DOK-oh-li-THI-ah-sis, then blend.

In US English, the sequence tends to be koo-LEH-doh-koh-li-THY-uh-sis with emphasis on the THY syllable within lithiasis. UK English often features a shorter /ɡ/ or clipped final -sis and a slightly shorter vowel in the first syllables; non-rhotic R may affect the roll, but the main rhythm remains four-beat. Australian tends to be similar to US but with broader vowels and a more pronounced 'i' in -iasis, resulting in koo-LUH-doh-koh-li-THY-ah-sis. Always anchor the -li- and - THI- parts for intelligibility.

Because it blends multiple morphemes: choledocho- (bile duct), lith- (stone), -iasis (pathological condition). It’s five to six syllables with increasing consonant clusters: /ˌkoʊ.lə.dɒk.oʊ.lɪˈðaɪ.ə.sɪs/. The long, multi-morpheme structure and similar-sounding segments (-doch-, -doh-, -lith-) increase chances of misplacing stress or dropping syllables. Focus on segmenting into choledocho-li-thi-a-sis and maintaining a steady tempo.

No silent syllables; every segment is articulated. The standard is four primary stress-bearing units, with emphasis on lith- in lithiasis. In clinical dictation, you should stress the -li- in lithiasis to distinguish from cholelithiasis. Pronounce all consonants clearly: choledocho-li-thi-asis, and avoid truncating the -sis ending.
