Nasal sound /ŋ/

[celtaflorida]

Greetings.
In words with nasal sounds such as 'sing, ring, everything,' etc, should there be weak /g/ sound at the end? or a weak /k/ sound at the end of 'bank' for example.
Many thanks.

For most native speakers, no. Speakers of some dialects do end with a /g/.

or a weak /k/ sound at the end of 'bank' for example.

Where the word ends with the letter k, the final sound is normally /k/.
