Understanding ARPABET Pronunciation

Want to hear it? Click the Listen button to hear the browser speak the word using text-to-speech!

The pronunciation guide uses the ARPABET phonetic system—the same system used in speech recognition and text-to-speech applications.

Vowel Examples:
AE1 = cat, bat
EH1 = bed, head
IY1 = see, me
OW1 = go, boat
UW1 = boot, do
Stress Numbers:
0 = no stress (unstressed)
1 = primary stress (loud)
2 = secondary stress (medium)
Example:
AH0 TH IY1 N AH0
= a-THEE-na (Athena)

The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

A temperature scale beginning at absolute zero. It is widely used in physical science and measures thermal energy.

Detailed Definition
The kelvin is the base unit of thermodynamic temperature, beginning at absolute zero, where matter reaches its lowest possible thermal energy. Unlike Celsius, the Kelvin scale does not use degrees in its standard name. In poetry, Kelvin can make coldness feel exact and cosmic: a star's blazing surface, an empty winter field, or the nearly unimaginable hush near absolute zero. Its numerical rigor can sharpen contrasts between measured heat and human warmth.
Example
Example in poetry:
“At 273.15 kelvin, water reaches its freezing point,” gives a precise scientific use of the absolute temperature scale; A poet might write, “The laboratory cooled the sample toward zero kelvin, where motion nearly falls silent”; “Her room felt like two hundred kelvin, though the radiator hissed,” uses Kelvin for exaggerated coldness; In a space poem, “The star’s surface burned at thousands of kelvin,” conveys temperatures beyond ordinary weather.
Additional Notes
Kelvin measures temperature from absolute zero, where thermal motion is minimal. Unlike Celsius, Kelvin has no negative temperatures in ordinary use.
