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 process of combining two vowels into a single gliding syllable, affecting scansion and rhythmic flow in poetic lines.

Detailed Definition
Diphthongization merges adjacent vowels into a diphthong, compressing syllables to accelerate pace or smooth transitions in verse, common in languages with fluid phonetics like English or Greek. In Chaucer's Canterbury Tales, it aids Middle English rhythm, creating melodic glides that enhance storytelling's oral quality; its significance in literature lies in facilitating natural speech patterns within strict meters, allowing poets to evoke motion or intimacy—appearing to humanize formal structures, it bridges prosody and dialect, enriching cultural authenticity and inviting performers to capture the era's sonic essence.
Example
Example in poetry:
In Chaucer's "The Knight's Tale," diphthongization merges "day" sounds in Middle English for smoother heroic couplets; Shakespeare's Elizabethan pronunciation diphthongizes "time" to "tahm," affecting iambic rhythm; Educational: Modern adaptation of "The road not taken" with diphthongized "way" for gliding stress; In Welsh poetry influences, diphthongization creates melodic lines in Dylan Thomas' villanelles; For practice, rewrite "I wander lonely" emphasizing diphthong in "lonely" for fluid anapest.|In Anglo-Saxon verse, diphthongization in "ealdor" adds resonance to alliterative rhythm; Students analyze diphthongization in Keats' "La Belle Dame" for euphonic effect.
Additional Notes
Diphthongization glides vowels for fluid scansion, teaching students phonetic evolution in historical poetry like Chaucer's, linked to monophthongization for contrast; it smooths Middle English rhythms; professors can trace its impact on Elizabethan pronunciation; tip: in modern adaptations, emphasize diphthongs in recitation to mimic oral traditions, helping compose lines where merged sounds accelerate pace, illustrating prosody's adaptation to dialect for natural, melodic flow.
