One syllable: Hertz.
herts
/hɛɹts/
Hertz is pronounced herts (/hɛɹts/). It has one syllable (Hertz), with the stress on "Hertz". Hertz refers to the unit of frequency, equal to one cycle per second, commonly used to measure sound or signal frequency. It can also refer to Heinrich Rudolf Hertz, the physicist who demonstrated electromagnetic waves. In everyday use, ‘Hertz’ appears in contexts like audio specs, radio, and science, and is especially familiar to engineers, musicians, and students of physics.

- Vowel drift: Speakers often longer or shorter the /ɜː/; keep it steady as /ɜː/ rather than a lax /ɜ/ or /ə/. - Final cluster error: Many drop /t/ before /s/ or insert a vowel: avoid saying /hɜːrt s/ or /hɜːrts/ with a hiatus. - R-coloring: Americans expect a rhotic /r/; in non-rhotic accents, the /r/ may be weak; to maintain clarity, articulate /r/ distinctly before the /t/ start. Correction tips: practice minimal pairs with a clear /t s/ release; use finger tap to time the /t/ release; recite phrases like “hertz units” slowly then speed up.
"The speaker delivers audio at 44,100 Hz, which affects the fidelity of the recording."
"Her professor explained that the sampling rate must be at least 44.1 kHz to avoid aliasing."
"We measured the room’s resonant frequency in hertz to identify problematic modes."
Pronounce it as /hɜːrts/ in US and UK English, rhotacized with an initial “h” and a mid-central vowel /ɜː/ before the /r/. The final /ts/ is a crisp voiceless affricate. For Australian speakers, /hɜːts/ is typical, with a slightly longer /ɜː/ depending on regional vowel length. Visualize lips relaxed, tongue central, tip lightly touching the alveolar ridge as you glide into the /t/ and release into /s/. Audio cue: a short, clean ‘h’ onset, then steady /ɜːr/ then a precise /ts/.
Common mistakes include saying /hɜːrts/ with a dropped /r/ (non-rhotic) in American contexts, or turning the final /ts/ into a simple /t/ or /s/ cluster. Some speakers lengthen the vowel too much, making /hɜːrts/ sound like /hɜːrtɒs/. To correct: keep a crisp /t/ followed directly by /s/—as in an abrupt /t s/ sequence—avoid vowel clustering or extra vowel intrusion between /r/ and /t/. Practice by drilling /ɜːr/ then a tight /ts/ release.
In US/UK: /hɜːrts/ with rhotic R and a short, tense /ɜː/. In many US dialects, /ɜː/ may be realized closer to /ɝ/ (as in birds), but still with /r/. In some non-rhotic accents (certain UK dialects) you might hear a weaker or non-rhotic /r/, affecting the surrounding vowels. Australian tends to have a rounded, centralized /ɜː/ with a clear /r/ depending on whether the speaker is rhotic; the ending /ts/ remains a crisp affricate. Overall, retain the /r/ and the tight /ts/ release across accents, adjusting vowel quality slightly per region.
The difficulty comes from the combination of a mid-central vowel /ɜː/ followed by an /r/ and a final /ts/ cluster, which can create a blend or vowel-tapping effect for non-native speakers. The challenge is keeping the /r/ clear before the voiceless /t/ and ensuring the /t/ is released into /s/ without a vowel between them. Another challenge is avoiding assimilatory changes where /r/ is silent or merges with adjacent consonants in rapid speech. Practice sharp, precise articulation of each segment.
A unique angle for ‘Hertz’ is recognizing its dual identity as both a unit of frequency and a surname. When used as a unit, you emphasize the first syllable /hɜːr/ with a crisp /r/; the second syllable is a tailed /ts/. When referencing Heinrich Hertz in speech, some speakers slightly modify the vowel quality or length in the name, but in most contexts the pronunciation remains /ˈhɜːrts/ for the surname in English as well. Keep attention on the affricate at the end to avoid a simple /t/ or /s/.

- US: rhotic /r/, tenser /ɜː/; keep /r/ pronounced and avoid vowel shortening before /ts/. - UK: often non-rhotic in some variants; if rhotic speakers, ensure /r/ is audible; use slightly lighter /r/ and a shorter /ɜː/. - AU: generally rhotic but vowel can be more centralized; maintain clear /r/ and crisp /ts/; some vowels may resemble /ə/ in rapid speech. IPA references to compare: US /hɜːrts/, UK /hɜːts/, AU /hɜːts/; keep /r/ before /t/ in all.
Hertz originates from the German physicist Heinrich Rudolf Hertz (1857–1894), who experimentally confirmed the existence of electromagnetic waves and demonstrated their properties in the late 19th century. The term Hertz as the unit of frequency was adopted by the International Electrotechnical Commission in 1930s and later adopted by the SI system; the symbol Hz denotes cycles per second. The concept traces back to the Fourier analysis and wave theory, evolving from the older term ‘cycles per second’ to the standardized SI unit. The name honors Hertz’s pioneering work in radio waves, wireless communication, and wave propagation, which laid the foundation for modern communications and signal processing. While the unit is ubiquitous in physics and engineering, the word itself is also a proper noun in reference to the surname Hertz, leading to occasional confusion when discussing the person versus the unit. In usage today, Hz is used across disciplines, from acoustics to electronics, to quantify frequency, with higher Hz indicating faster oscillations or higher pitch in audio contexts.
