The words kept, slept, crept, except and accept all end with the same rhyming sound /ept/ (spelled -ept or -pt in writing). Note that apt /æpt/ looks similar but has a different vowel sound, so it does not rhyme with them. The abbreviation pt itself is usually read as two separate letters, /ˌpiːˈtiː/, not as a single /pt/ sound.
