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 shortening or compression of a syllable or foot, opposite of diastole

Detailed Definition
Systole contracts duration or emphasis, typically applied to naturally long syllables pronounced short to fit metrical requirements, particularly in quantitative classical verse. In classical and experimental modern poetry, systole demonstrates the poet's technical mastery of prosodic flexibility; it allows compression of material within fixed metrical schemes while maintaining semantic clarity, showing how form and meaning can coexist through sophisticated prosodic manipulation.
Example
Example in poetry:
In Greek metrics, systole shortens a long syllable to fit meter, as in dactylic substitution; In Latin poetry, systole allows “āēr” to be scanned as two short syllables; In English, systole appears when poets compress words like “heaven” to one syllable (“’ven”) in hymns; In Shakespeare’s sonnets, “even” may undergo systole to “’ven” to maintain iambic rhythm; In Milton’s “Lycidas,” “flow’rs” represents systole of “flowers” to one syllable; In Greek lyric, systole enables metrical flexibility in Aeolic verse.
Additional Notes
Systole in prosody refers to the metrical shortening of a normally long (or stressed) syllable to fit a rhythmic pattern—essentially the opposite of diastole (lengthening). Though more relevant in quantitative meters (Greek/Latin), systole can occur in English when a typically stressed syllable is demoted to fit iambic flow (e.g., "paradise" with stress on first syllable forced into unstressed position). It reflects the flexibility poets employ to maintain meter without distorting meaning.
