Every name has a story.
Yours, in Telugu.

English examples are approximate and vary by accent. The Telugu letters help a Telugu speaker identify the sound.

a / aa: అ “u” in cup / ఆ “a” in father.
i / ee: ఇ in sit / ఈ in see.
u / oo: ఉ in put / ఊ in moon.
e / ae: ఎ short “e” in get / ఏ longer, steady “ay” in say.
o / long o: ఒ short “o” / ఓ longer “o” in go. The spelling “oo” can mean this sound in some names; choose by sound, not spelling. It usually means ఊ, as in moon.
ai / ow: ఐ in eye / ఔ in cow.

t / ṭ, d / ḍ: త ద with tongue touching upper teeth / ట డ with tongue curled back. English t and d are only approximations.
th / ṭh, dh / ḍh: థ ఠ ధ ఢ add a puff of breath to the corresponding sound; “th” here is never the English th in thin or this.
p / ph, k / kh: ప క plain / ఫ ఖ with a puff of breath. “ph” is not automatically f.
ch / c: both can label చ, like ch in chair; neither means k as in Michael. ఛ adds a puff of breath.
sh / ṣ: శ as in ship / ష with tongue curled back.
n / ṇ: న with tongue forward / ణ curled back, as in the traditional pronunciation of Krishna.
