/ˈθɜːrməˌkuːpəlz/
thermocouples is pronounced THURR-muh-koo-puhlz (/ˈθɜːrməˌkuːpəlz/). It has four syllables (ther-mo-cou-ples), with the stress on "ther". Thermocouples are temperature-sensing devices made of two dissimilar metals joined at one end, producing a voltage proportional to temperature. They operate based on the Seebeck effect and are widely used in industrial and scientific settings to measure high temperatures. The term encompasses multiple configurations and materials, including thermocouple types K, J, and Type-T sensors.

"The engineer installed several thermocouples along the furnace lining to monitor heat distribution."
"We calibrated the thermocouples before starting the high-temperature bake."
"Thermocouples provide fast response times compared with RTDs in extreme temperatures."
Pronounced as /ˈθɜːr.moʊˌkuː.pəlz/ (US) or /ˈtɜː.məˌkʌp.əlz/ (UK/AU). The primary stress is on the first syllable (THERM-o), with secondary stress on the third syllable in many speakers. Start with the voiceless th as in thin, then “er” with a mid-back vowel, followed by ‘mo’ as /moʊ/ or /mʌ/ depending on accent, then ‘cup’ as /ˈkʌp/ or /kʌp/, and end with ‘ples’ sounding like /pəlz/. Ensure the final z is a clear voiced sibilant. Audio cue: think “THERM-uh-KUP-uls.”
Common errors: (1) Misplacing the stress, say ‘ther-MO-cou-ples’ instead of ‘THER-mo-cou-ples’; (2) Slurring the ‘cou’ into ‘cook’ or making /kuː/ in US as /kjuː/; (3) Final syllable mispronunciation, producing ‘puls’ or ‘pulls’ instead of /pəlz/. Correction tips: keep primary stress on the first syllable, pronounce ‘cou’ as /ˈkʌp/ or /kəp/ depending on dialect, and clearly vocalize the final /əlz/ with a light schwa before the z. Practice slow with minimal pairs to stabilize segments.
US tends to pronounce as /ˈθɜːr.moʊˌkuː.pəlz/ with /ɜːr/ and a long /oʊ/ in ‘mo’ and a fuller /uː/ in ‘cou-’. UK/AU favor /ˈtɜː.məˌkʌp.əlz/ with a shorter first vowel and a more clipped /ˌkʌp/; rhoticity varies: US is rhotic, UK and AU can be non-rhotic in careful speech; AU often emphasizes the second syllable slightly more, giving a clearer /kəp/ or /kʌp/. IPA references: US /ˈθɜːr.moʊˌkuː.pəlz/, UK/AU /ˈtɜː.məˌkʌp.əlz/.
Difficulties stem from the cluster 'thermo-' with a strong initial /θ/ followed by a rhotic vowel and then a multi-syllabic sequence /ˌkjuː.pəlz/ or /ˌkʌp.əlz/. The challenge is accurate placement of primary stress on the first syllable and producing the mid-central schwa in the middle syllable with a clear, unambiguous final /əlz/. Also, the 'cou' can be mispronounced as /kuː/ or /kaʊ/; practice with minimal pairs to land the intended /kə/ or /kʌ/ before /pəlz/.
The unique aspect is the three-syllable rhythm with a heavy initial stress and a trailing -ples that many non-native speakers misinterpret as ‘-poo-lz’ or ‘-pulz’. Emphasize: THERM-mo-kup-ples with a crisp /pəlz/ at the end. The presence of the /θ/ sound near a vowel cluster and the /ˌkuː/ versus /ˌkʌ/ variation makes exact articulation essential for understanding in technical dialogue.

The term thermocouple derives from Greek therme meaning heat combined with k principal ‘couple’, designating two dissimilar metals joined to generate voltage when heated. The concept emerged from the study of thermoelectric effects in the early 19th century, with Seebeck’s discovery in 1821 showing that a current is produced when two different metals are placed at different temperatures. Early research by Thomas Seebeck and later refinements by joule’s work and the development of practical sensors by the mid-20th century solidified thermocouples as standard high-temperature sensors. The word first appeared in technical literature in the mid-1900s as industrial thermocouple usage expanded into aerospace, power generation, and process control.
