You say /ˌən.dɪˈtɛk.tɪd/ in US/UK/AU. Stress falls on the third syllable of a four-syllable word: un- | di- | tected. Start with a schwa /ə/ in the first syllable, then a short /ɪ/ in the second, then the stressed /ˈtɛk/ with an open-mid front vowel, and end with /tɪd/ as a light, quick ending. Keep the 't' sounds tightly joined in the middle consonant cluster to avoid an extra syllable. Audio reference: try hearing the word in standard dictionaries or pronunciation videos to synchronize mouth movements.
Two common errors: (1) Misplacing primary stress on the wrong syllable, producing un-DI-TECT-ed instead of un- di- TECT-ed. (2) Weakening or slurring the 't' cluster in 'tect,' leading to /tɛk/ becoming /tɛk/ with a reduced or silent middle consonant; keep a crisp /t/ followed by a clear /ɪ/ before /d/. Correct by isolating syllables and practicing the middle consonant cluster: /ˌən.dɪˈtɛk.tɪd/.
In US, the 'un' often reduces to /ən/ with lighter initial emphasis, and rhotic /r/ is not present in this word itself but can affect surrounding vowels if connected. In UK, the /ˌən.dɪˈtɛk.tɪd/ is similar, but non-rhoticity may influence linking; you might hear clearer enunciation of the second syllable. In Australian, vowel quality may be slightly broader, with a more centralized /ə/ in the first syllable and a crisp /t/; stress remains on the /ˈtɛk/ syllable. Overall, the main consonants and stress pattern stay consistent, while vowel quality and link speech vary.
The difficulty lies in the consonant cluster /t/ followed by /ɪ/ and /d/ in rapid speech, which creates a potential for assimilation or elision; some speakers may drop the /d/ or merge /tɪd/ into /tɪd/ or /tɪd/. The sequence /dɪˈtɛk/ requires precise articulation to prevent a slipped vowel or a mis-timed stop. Additionally, the prefix 'un-' with a short vowel can compress in fast speech, reducing clarity. Focusing on sustaining the /d/ release and the /t/ timing helps clarity.
The word features a three-syllable-to-four-syllable stress pattern with the primary stress on the third syllable, creating a noticeable peak in amplitude during /ˈtɛk/. The prefix un- often reduces to a schwa /ə/ when spoken quickly, affecting the overall rhythm. This makes you focus on the middle consonant /t/ and its following vowel /ɪ/ as a key anchor for rhythm and intelligibility.

Undetected is formed from the prefix un- (a negative or opposite force) + detect (from Latin detegere ‘to uncover, reveal’ with de- meaning ‘undo’ and tegere ‘to cover’). The root detect comes from Latin detectus, past participle of detegere, which combines de- ‘un- / undo’ with tegere ‘to cover or protect’. The sense of detect emerges via medieval Latin detектare and Old French detecter before entering English as detect. The prefix un- connotes negation or opposite state and has been productive in English since at least the 14th century, while detect acquired its more modern sense of discovering something hidden by the 17th century, especially in scientific and investigative contexts. By the 19th and 20th centuries, undetected became common in medical, security, and technical language to denote things that have not been observed or identified despite scrutiny, testing, or surveillance. The term retains a precise implication: there exists something that should have been observed but was not. The construction emphasizes a latent or concealed status, often carrying a subtle tone of vulnerability or exception to detection. Overall, undetected has evolved to describe unseen phenomena across domains, with its core meaning centered on absence of detection rather than absence of existence. First known use in English traces to early modern usage around the 16th-17th centuries, aligning with the broader adoption of un- and detect compounds in scientific discourse of that era.
