If the Correction Menu doesn’t contain your desired text, one solution is to just type over it. Another is the command "spell that."
Say: Patterssen HYPHEN Smith
Notice that Dragon didn't spell the first word as intended.
Say: CORRECT Patterson
Say: SPELL THAT
In the Spelling window, you could type or spell the correct word, and play back the audio.
Say: MICROPHONE OFF
Note: you could learn more in Help with a command such as "search help for spelling characters."
