A court reporter is someone who listens very carefully to what people say in court and writes it all down. They use a special machine called a stenotype machine that has a lot of keys with lots of letters and symbols on them. Instead of typing the words out on a computer, court reporters use these keys to create a special code that only they know how to read.
They do this because in court, people talk really fast and everyone is talking at the same time, so it's hard to take notes on everything that's said. The court reporter's job is to make sure that they catch every single word that is said, even if they're talking really quickly or quietly.
Once the court reporter has written everything down, they can then type it all up into a transcript, which is like a big document that copies down everything that was said in court. These transcripts are really important for lawyers and judges because they help them remember everything that was said during the court case.
Overall, a court reporter is a person who listens really well, writes down everything that is said using a special machine, and then creates a transcript of the court case for lawyers and judges to use.
