How can I stop the transcription tool from turning words into profanities?

Is there any way to block the transcription tool from using profanity? I want to block certain words from being able to appear.

I was planning to use the podcast tool with middle school students (grades 7 & 8 ages 12-14). Today while demoing the tool for students- on the screen in front of the class- the transcription showed up with a high level profanity for all of the students to see. This was not the word the student had used. The tool needs a way to filter any profanity from ever appearing, even if it is what the student tried to say. Otherwise I don’t know if I can use it. It really is so easy for students to edit, I’d hate to lose it.
