I don't know what you have in mind when you say "regular address".
Bech-32 encoding is a rather simple encoding of any data that takes an octet string (8 bits) convert it to 5 bit chunks and then converts each chunk to one of 32 characters defined by BIP-173 (that is qpzry9x8gf2tvdw0s3jn54khce6mua7l).
For an address we add the witness version as its first 5-bit chunk without needing any conversion so when it is 0 you choose the first char that is "q" and when it is 1 you choose the second that is "p" and so on.
they are all "regular addresses" with a different version.
