/ˌmɑdʒəˈleɪʃən/
modulation is pronounced mah-juh-LAY-shuhn (/ˌmɑdʒəˈleɪʃən/). Modulation refers to the act or process of varying a parameter, such as volume, pitch, or frequency, within a system or signal, often to convey nuance or adapt to different contexts. It can also describe the adjustment of musical dynamics or the alteration of a signal in communications. In broader use, it denotes controlled change to achieve a desired effect or compatibility.

You say /ˌmɒd.juˈleɪ.ʃən/ in US English, with primary stress on the third syllable. In UK English it’s /ˌmɒ.djʊˈleɪ.ʃən/ and in Australian English /ˌmɒ.dʒʊˈleɪ.ʃən/. Note the trois-syllable sequence: mod-u-la-tion, with a light, schwa-like final -tion. Pay attention to the syllable boundary after -ju- and keep the vowel in -leɪ- steady and clear.
Common mistakes include reducing the middle syllable, saying /ˈmɒdjʊˌleɪʃən/ with wrong stress, and slurring -leɪ- into -lé- or -lət. Focus on stressing the -leɪ- (ˈleɪ) and articulating the final -ʃən clearly as /-ʃən/. Practice by isolating each segment: /ˌmɒd/ + /ˌjuː/ + /ˈleɪ/ + /ˈʃən/, then blend. You’ll hear the natural rhythm when you maintain a light secondary stress on the first two syllables and emphasize the third for clarity.
Across US/UK/AU, the primary stress sits on the third syllable, but vowel quality changes: US often uses /ˌmɒd.juˈleɪ.ʃən/ with a more open /ɒ/ in the first syllable and /ju/ as a clear /juː/; UK shows /ˌmɒ.djʊˈleɪ.ʃən/ with a shorter /djʊ/ and non-rhotic /r/ absence; AU keeps a broad /æ/ or /ɒ/ variation with a slightly more rounded /ɪən/ leading to /ˌmɒ.dʒʊˈleɪ.ʃən/. In all, the -leɪ- is a distinct, stressed nucleus, while the final -ʃən remains a light, unstressed ending.
The difficulty lies in the cluster /dʒ/ or /dj/ combination after /mɒd/. In many accents, you transition from a hard /d/ to a near-palatal /j/ without creating a pronounced break, which can cause an awkward glide. Additionally, the three-stress pattern on a multi-syllable word requires precise timing: secondary stress on the first syllables and primary stress on the third. Mastery comes from clear articulation of /ˈleɪ/ and a soft, efficient /t/ leading into -ʃən in rapid speech.
Yes. In technical contexts like electronics or audio engineering, you’ll encounter phrases like “frequency modulation” or “depth of modulation.” When saying them in sequence, maintain consistent syllable weight and avoid rushing the -ˈleɪ- portion to keep the rhythm intact. The cadence tends to slow slightly in formal dictation or academic talk, so you’ll naturally place a tiny pause after the -ju- syllable before the stressed -leɪ-.

Modulation comes from Latin modulatio, from modulus (small measure, measure, standard) and the verb modulus originated in Roman law and music theory, where it referred to the measure or the manner of forming something. The earliest sense in English traces to late Middle English, adopted from French modulation or directly from Latin modulatio. Over time, it broadened beyond music to describe any method of shaping or adjusting a signal or parameter. In early 18th-century technical discourse, modulation primarily described changes in musical keys. By late 19th and 20th centuries, with the advent of electrical engineering and communications, the term expanded to electronic signal processing (AM/FM modulation, phase and amplitude modulation). The word carried into digital domains, where it now encompasses modulating light, data, or user interfaces, while retaining its core meaning of controlled alteration. The first known uses appear in scholarly treatises on acoustics and telecommunication in Europe, with English attestations appearing in the 1700s and becoming common in technical literature by the 1900s. Today, modulation is a staple term in music, engineering, telecommunications, and user-experience design, always signaling purposeful, measured change.
