Is It Legal to Record and Transcribe a Phone Call Without Consent?
Recording rules vary by state, and courts are now asking what your transcription tool does with the audio, not just who consented.
Someone asked me last week if it is legal to record a sales call without telling the other person. I did not have a clean answer. I built a transcription company and I still had to look it up.
That is the honest state of call recording law. It is not one rule. It is dozens of state rules stacked on top of a federal one, and lately the tool you use to transcribe the call matters almost as much as the law itself.
One-party consent vs. two-party consent
Federal law, 18 U.S.C. § 2511, lets you record a call if you are a party to it. You do not need the other person's permission under federal law alone, and most states follow that same one-party rule.
Eleven states go further: California, Delaware, Florida, Illinois, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Pennsylvania, and Washington require every party to consent before you record. Record someone there without asking, and you can face criminal charges, not just a civil suit.
Calling across state lines does not let you dodge this. If either person is in an all-party state, the stricter rule wins. Assume the tougher law applies, and ask first.
Consent is not the only question anymore
A court fight over Otter.ai changed how I think about this. In In re Otter.AI Privacy Litigation, a federal judge in California ruled in August 2026 that Otter could be treated as a third-party eavesdropper under California's wiretap statute, not just a recording tool used by one of the call's own participants. The distinction: Otter did not just capture the call, it kept the audio and used it for its own purposes, including model training.
That ruling matters even if you never touch Otter. It says that consent from the humans on the call is not the end of the analysis. What the transcription tool does with your audio afterward, whether it stores it, whether it trains on it, is now a live legal question too.
What this means if you record calls for work
- Say out loud that you are recording, right at the start. It costs five seconds and it settles consent everywhere, including all-party states.
- Check where the other person is calling from before you assume your home state's rule applies.
- Ask any transcription tool what happens to the audio after it processes it. Deleted, retained, or used for training? Get a straight answer, not a vague line about service improvement.
- Apply the same rule to in-person meetings in all-party states, since the consent requirement is not limited to phone calls.
None of this is legal advice. Rules change by state and courts are still working out how AI note-takers fit into decades-old wiretap statutes. But the direction is clear: consent from the people on the call is necessary, not sufficient.
Transcribe-It exists because I wanted a tool that answers the audio question honestly: your file goes to AssemblyAI for transcription, gets deleted from our storage right after, and the transcript is purged once your job completes, so you get a summary and action points without the tool quietly becoming a data warehouse.
