Vowel Extension

In words that consist of only one mora?, the vowels at the end tend to extend and become two mora. For example:

Word Standard Kansai-ben

mind きぃ
tree きぃ
hair けぇ
four しぃ

height せぇ
blood ちぃ
hand てぇ

Also, for verbs where the stem? consists of one mora, the end vowel sometimes extends depending on the conjugation.
