3 syllables: im, puls, es. Stress on im.
IM-puhl-siz
/ˈɪmpəlsɪz/
impulses is pronounced IM-puhl-siz (/ˈɪmpəlsɪz/). It has three syllables (im-puls-es), with the stress on "im". Impulses are sudden urges or drives that prompt action, often triggering rapid or instinctive responses. In psychology and physiology, impulses refer to nerve signals or motivational cues that initiate movement or behavior. The term can also describe brief, but strong, impulses governing decisions or actions in various contexts, from electronics to social behavior.

"The scientist studied how neural impulses move signals from one neuron to another."
"You should resist impulsive spending and take a moment to think before buying."
"In electronics, impulses can create rapid, short-lived voltage spikes."
Pronounce as /ˈɪm.pʌl.sɪz/ in US/UK/AU. The stress is on the first syllable: IM-pluls-es. Break it into 3 syllables: im - pults - es, with a light schwa in the second syllable’s second vowel. The final -es sounds as /ɪz/ in most contexts. Keep the tongue close to the alveolar ridge for the ‘l’ and avoid an extra vowel after the ‘s’. Audio resources: Cambridge/Oxford dictionaries typically provide native-speaker audio; you can also listen to related words like impulse to hear the singular form for comparison.
Two frequent errors: misplacing the stress or slurring the middle consonant cluster. First, some learners place stress on the second syllable (im-PUL-ses) instead of the correct IM-pluls-es; ensure primary stress on the first syllable. Second, learners may mispronounce the /l/ as a vowel-ish sound or mis-handle the /z/ at the end, producing /-zɪz/ or /-sɪz/. Correct it by timing the final /z/ as a voiced alveolar fricative and keeping the final vowel as a short /ɪ/ before /z/. Practice with minimal pairs: 'impulse' vs 'impulses' to hear the plural ending clearly.
In US, UK, and AU accents, /ˈɪm.pʌl.sɪz/ is broadly similar, with rhoticity affecting surrounding vowels in connected speech. US accents may have a slightly tighter /p/ release and pronounced /ɪ/ in the first syllable; UK speakers often have a crisper /l/ and a shorter /ɪ/ in the first syllable depending on vowel environment; Australian English tends toward a more centralized /ʌ/ and may reduce vowel length slightly. The final /z/ remains voiced in all; non-rhotic variants may link with following vowels differently in fast speech, but the basic sequence IM- pul-ses remains recognizable.
The main challenge is the three-syllable rhythm with a clear primary stress on the first syllable and a voiced alveolar fricative ending. The cluster /m p/ requires precise stop-release timing, and the stretch from /əl/ to /sɪz/ must be smooth to avoid an intrusive schwa. People often mispronounce as 'im-pulses' with reduced second syllable or replace /ʌ/ with /æ/. Practicing with slow slowed pace and deliberate tongue position helps: keep lips rounded slightly for /p/, raise the tongue for /l/, and maintain voicing through the final /z/.
A useful tip is to pair the plural ending with a light assimilation: ensure the /z/ is voiced and blends with the preceding /s/ without an extra sibilant. Say the phrase 'neural impulses' slowly, then gradually speed up, focusing on the transition from /l/ to /s/ and then to /ɪz/. Tip: practice with the phrase 'natural impulses' to reinforce the /ɪz/ ending and avoid devoicing the final consonant. Listen to 'impulse' in pronunciation guides and compare to the plural to feel the added syllable and final z sound.

Impulse comes from the Latin impulsum, past participle of imponere ‘to push on, force,’ from in- ‘in, on’ + pellere ‘to push’. The English form impulse appeared in the 16th century, originally conveying a push or sudden impetus. In middle to late 19th century science, psychology and physiology adopted the term to describe nerve or motor triggers, evolving to encompass a broad sense of sudden motivational forces. By the 20th century, ‘impulse’ broadened to refer to brief stimuli that elicit automatic responses, including electrical impulses in circuits and behavioral impulses in humans. The plural ‘impulses’ follows standard English morphology with -es, pronounced /ˈɪmˌpʌl.sɪz/ in typical usage, though stress and vowel quality can shift with dialect. First known use citations include medical and natural philosophy texts; the term grew in scientific literature with the rise of neurology and cybernetics, solidifying its current, multi-domain meaning across psychology, electronics, and everyday speech.
