What is an upsidedown "e" called when used in the pronounciation of a word?

Answer 1

Schwa

Answer 2

An unstressed and toneless neutral vowel sound in any language, often but not necessarily a mid-central vowel. Such vowels are often transcribed with the symbol <ə>, regardless of their actual phonetic value.
The mid-central vowel sound (rounded or unrounded) in the middle of the vowel chart, stressed or unstressed. In IPA phonetic transcription, it is written as <ə>. In this case the term mid-central vowel may be used instead of schwa to avoid ambiguity.
The Latin letter ə and the Cyrillic letter ә (see the respective articles).
The word "schwa" is from the Hebrew word שְׁוָא (šěwā’, /ʃəˈwa/), meaning "nought"—it originally referred to one of the niqqud vowel points used with the Hebrew alphabet, which looks like a vertical pair of dots under a letter. This sign has two uses: one to indicate the schwa vowel-sound and one to indicate the complete absence of a vowel. These uses do not conflict because schwa is, in Hebrew, an epenthetic vowel, the equivalent of "no vowel at all".
Sometimes the term "schwa" is used for any epenthetic vowel; however, different languages use different epenthetic vowels.
