make reverb better

hi there, is there any i can make like chanting aum to the vole sound like it’s longer in length? say 60 secs a little more? and which setting will do that in reverb?

It feels like you need echo, in stead of reverb. But It’s not quite clear. What are you trying to do?

what i’m trying to make the vowels of the letters that are a.u.m. sound like longer in length while the computer voice says the vowels a u m or the full word of aum sound like a whole word. this is for chanting. now i don’t know if auto tune can make this word aum make this sound like a chant or chants while the computer says it in it’s only voice recorded from dspeech. that’s what i’m looking for. i’m talking about auto tune in audacity.
