Near-open front unrounded vowel to Nasalized close-mid front unrounded vowel

The transformation from the near-open front unrounded vowel /æ/ (ash) to the nasalized close-mid front unrounded vowel /ẽ/ is a well-documented phonetic shift, primarily observed in certain dialects of English. This change typically involves two key processes: the raising of the vowel's tongue position and its nasalization, often triggered by the presence of a following nasal consonant. The acoustic effects of nasalization can make a low vowel sound higher, contributing to this combined shift.

Language Examples

æ→ẽ— In many dialects of North American English, the vowel /æ/ is raised and nasalized before nasal consonants (e.g., in words like 'man', 'camp', 'pan'). This allophonic realization can approach a close-mid front nasalized vowel.
