When a summary turns testimony into a cleaner story than the record supports
A civil deposition shows how machine-generated language can preserve the recognizable subjects of testimony while changing chronology, evidentiary status, symptom categories, speaker position, and the force of later clarification.
Source condition: interpreted civil deposition with repeated questioning, attorney characterization, objections, and later clarification.
Generation condition: ordinary off-the-shelf use of a general-purpose large language model to organize the deposition for case-evaluation use.
All personal names, firms, employers, providers, locations, route names, and case identifiers have been removed or replaced with role labels.
“Plaintiff’s truck struck the defendant’s vehicle at an angle.”

“Plaintiff attempted to walk this back, describing ongoing morning numbness — a direct inconsistency with his sworn written discovery response.”
“Claim asserted — plaintiff testified the accident has decreased/diminished his future earning ability.”
The summary also organizes portions of the testimony under “Potential Liability/Credibility Issues for Case Evaluation.”
“I just want to clarify the point that the accident happened at an angle and not frontal.”
“Are you experiencing knee pain today?” “No.” “Would you rate your pain in your left knee a zero today?” “Yes. It’s like numbness only.”

Impact: “Your car hit the defendant’s car, though, correct?” Counsel objects that the question mischaracterizes prior testimony.
Earlier left-knee testimony: the witness confirms a prior statement that left-knee pain resolved, then describes recurring morning symptoms including numbness.
Future earnings: “Because of your injuries in this case, are you making a claim for future earnings?” “Yes.”
What changed
The machine output does not replace the deposition with an obviously different case. The consequential changes occur in the relationships among statements: who supplied the wording, whether a proposition was asked or admitted, when clarification occurred, and whether the record had actually settled what the summary presents as complete.
“Plaintiff’s truck struck the defendant’s vehicle at an angle.”
“Your car hit the defendant’s car, though, correct?” Counsel objects that the question mischaracterizes prior testimony.
The transcript contains testimony about the vehicles meeting at an angle. It also contains resistance to the proposition that the witness’s vehicle was the actor that “hit” the other vehicle, counsel’s objection, and later clarification.
The machine sentence resolves those layers into one declarative proposition.
“Plaintiff’s truck struck the defendant’s vehicle.”
“I didn’t hit him. He hit us.”
“Struck” assigns grammatical agency: one vehicle becomes the actor, the other the object acted upon. The summary chooses a direction of agency from a record in which that direction was disputed.
Chronology emerges incrementally through repeated questioning, rephrasing, objection, and clarification.
A single sequence appears as though the witness narrated it in that form.
Chronological organization is a legitimate purpose of summarization. The QA question is whether organization remains distinguishable from resolution.
“attempted to walk this back ... a direct inconsistency”
“Are you experiencing knee pain today?” “No.” “It’s like numbness only.”
The phrase “walk this back” pre-classifies the later testimony as retreat from an earlier answer. “Direct inconsistency” then closes the interpretation before the later pain-versus-numbness distinction can do its full work.
Pain can be zero while numbness remains.
Continuing numbness demonstrates contradiction of resolved pain.
Once the categories are merged, the witness appears to have reversed himself more completely than the later testimony supports.
“Because of your injuries in this case, are you making a claim for future earnings?” “Yes.”
“the accident has decreased/diminished his future earning ability”
The source establishes that a future-earnings claim is being asserted. It does not, by itself, establish that future earning ability was in fact decreased or diminished.
A deposition is a multi-speaker record. It contains answers, leading questions, objections, counsel’s characterizations, interpreter interventions, and attempts to restate prior testimony.
Once those source boundaries disappear, a later reader can attribute to the witness language that originated elsewhere.
“Potential Liability/Credibility Issues for Case Evaluation”
A heading can perform analytical work before the reader reaches the underlying evidence. By organizing testimony under “credibility issues,” the summary tells the reader how to classify discrepancies or later clarification before those passages are independently evaluated.
Distributed testimony is organized; organization resolves ambiguity; resolved ambiguity becomes narrative; narrative begins to look like the witness’s own stable account.
Collision, symptoms, earnings, treatment, chronology.
Who supplied the wording, what remained disputed, what was clarified later, and what had not yet become fact.
The summary preserves what the testimony concerns more reliably than it preserves the form in which the testimony exists.
For transcript QA, legal-content review, investigation, claims work, research, and any workflow that compresses multi-speaker records, the relevant question is not only whether the summary mentions the right facts. It is whether a later reader can still recover who said what, under what wording, with what qualification, in what sequence, and whether the source had actually settled the proposition the summary presents as complete.
