3 syllables: A, my, lase. Stress on A.
AM-il-ayz
/ˈæmɪˌleɪz/
Amylase is pronounced AM-il-ayz (/ˈæmɪˌleɪz/). It has three syllables (A-my-lase), with the stress on "A". Amylase is a digestive enzyme that catalyzes the hydrolysis of starch into sugars. It is produced chiefly by the salivary glands and pancreas and plays a crucial role in the early stages of digestion. In biochemistry, amylase is often studied as a representative carbohydrase with notable activity on alpha-1,4-glycosidic bonds.

How to Pronounce Amylase
"- Saliva contains amylase, which begins starch digestion in the mouth."
"- Amylase activity increases in the pancreas during digestion."
"- Genetic defects can reduce amylase production, affecting carbohydrate metabolism."
Amylase is pronounced /ˈæmɪˌleɪz/ (American) or /ˈæmɪˌleɪz/ (British). Emphasize the first syllable AM, with a light secondary emphasis on the third position ‘lay’ syllable; the final ‘-ase’ sounds like ‘-z’ as in ‘zase’. Mouth positions: start with the jaw dropped slightly for /æ/, then raise the tongue for /mɪ/ and glide into /ˈleɪ/ with a clear long “a” vowel, finishing with a voiced alveolar sibilant /z/.
Common errors include: 1) Slurring the middle syllable so /ˈæmɪˌleɪz/ becomes /ˈæməˌleɪz/—keep /ɪ/ in the second position. 2) Misplacing stress, saying /ˈæmɪˈleɪz/ with stress on the second syllable; maintain primary stress on the first syllable and a weaker secondary on the third. 3) Ending with a soft /ɪz/ instead of /leɪz/—avoid an -eɪ- then z; keep /leɪz/ for the final syllable.
US, UK, and AU all render /ˈæmɪˌleɪz/ with primary stress on the first syllable and a rising diphthong in the second half. Differences occur in the /æ/ vowel quality (slightly tenser in British and Australian speakers), and in rhoticity: American tends toward a rhotic /r/ influence in connected speech, UK remains non-rhotic in formal contexts, and AU often leans toward General Australian vowel mergers that can slightly flatten the /eɪ/ to a near-diphthong. Overall, the core sequence /æ m ɪ ˈ leɪ z/ remains stable.
Two main challenges: the sequence /ˈæmɪˌleɪz/ places a lighter, short /ɪ/ between the stressed /æ/ and rising /leɪ/. This can trick learners into reducing or lengthening the middle vowel. Also, the final -ase is not /æz/ but /leɪz/, so learners often mispronounce as /ˈæmɪliz/ or /ˈæmɪlæs/. Focus on keeping the middle syllable distinct and simplifying the final vowel into a clean /eɪ/ before /z/.
Does amylase ever reduce to a two-syllable form in rapid technical speech, and how should you handle it? In careful speech you say /ˌæmɪˈleɪz/, two-pronounced syllables when speed reduces; but precise enunciation, especially in lecturing or diagnostics, preserves three syllables: /ˈæmɪˌleɪz/. When speed is a factor, keep the first syllable intact and semi-reduce the middle while maintaining the long /eɪ/ before /z/.

Amylase derives from the Greek amylon meaning starch and the suffix -ase denoting a enzyme. The term first appeared in the 19th century, reflecting the discovery of enzymes as biological catalysts. The Greek root amylon was used in early 19th-century texts to describe starch-like substances; later, amylase was defined to include enzymes that hydrolyze alpha-1,4 glyceridic bonds in starch and similar polysaccharides. The classification progressed with biochemical advances in carbohydrate chemistry, allowing precise naming of enzymes by substrate (amylase acting on starch) and mechanism (hydrolysis). By the mid-20th century, clinical and digestive physiology literature standardized “amylase” to refer specifically to salivary and pancreatic enzymes, with assays developed to quantify its activity in saliva, serum, and pancreatic juice. The current usage spans basic biochemistry, clinical diagnostics, and industrial applications like starch processing and fermentation. First known uses appear in pharmacological and physiochemical treatises of the late 1800s, expanding through the discovery and isolation of pancreatic juice components in the early 1900s.
