A more thorough explanation:

An official shorthand writer, also known as a court reporter, is a person who records testimony during legal proceedings. This can be done through stenography or electronic means. They are also responsible for preparing a transcript of the recorded testimony when requested.

For example, during a trial, the court reporter will sit in the courtroom and use a stenotype machine to record everything that is said. This includes the testimony of witnesses, the judge's instructions to the jury, and any objections made by the lawyers. After the trial, the court reporter will use their notes to create a written transcript of the proceedings.

Another example of when a court reporter may be needed is during a deposition. A deposition is a legal proceeding where a witness is questioned under oath by a lawyer. The court reporter will record everything that is said during the deposition and create a written transcript for later use in court.
