Understanding ARPABET Pronunciation

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

The distance between matching points on successive waves. It helps determine a wave's color, pitch, or energy.

Detailed Definition
Wavelength is measured from one crest of a wave to the next corresponding crest, or between comparable points in any repeating wave pattern. In visible light, different wavelengths are perceived as different colors; in sound, they relate to pitch. Poets often use wavelength figuratively for sympathy or shared understanding, but its science adds richness: two people may seem aligned while carrying different frequencies, distances, and energies through the same air.
Example
Example in poetry:
“Her voice had a long wavelength, low enough to tremble the window” links sound pitch to wave physics; A poet can use changing wavelength in light to describe a sunset shifting toward red; “Across the wavelength between us, the radio found only static” makes electromagnetic transmission a metaphor for failed communication; In a sea poem, wavelength can describe the measured distance from one wave crest to the next, creating a calm, observant rhythm
Additional Notes
Wavelength is measured from one wave crest to the next. Shorter light wavelengths appear bluer, while longer ones appear redder; for sound, wavelength relates to pitch.
