The term used to describe a person with specialized training who provides expert testimony in a trial is "Expert witness." This designation applies to individuals whose expertise in a certain field is recognized and who can offer opinions or conclusions based on their specialized knowledge. In legal proceedings, expert witnesses are crucial as they help the court understand complex subjects beyond the knowledge of an average juror.

An expert witness's role often involves clarifying technical details, providing research findings, or offering assessments based on their qualifications. Their testimony is intended to support one side of a case by providing an authoritative perspective, which can influence the outcome of the trial. They typically have advanced degrees, licenses, or extensive experience relevant to the matter at hand in court.

The other terms offered do not fit this specific definition: a witness simply provides testimony about what they have seen or heard; a consultant may offer advice or strategies in preparation for a case but does not testify in court; and a character witness speaks to the moral or ethical qualities of a party involved in the trial, rather than providing specialized knowledge based on training.
