Certified RCP-M CART Provider · NVRA Certified
Precision Captions LLC provides live, human-generated remote CART captioning for classrooms, ceremonies, lectures, and conferences. Not a machine guessing at your speaker’s accent. A trained, certified professional writing every word in real time — and a polished transcript in your hands within two hours.
The Human Difference
Automatic speech recognition — the AI behind every “auto-caption” button — has improved. It still is not access. It has no ear for a heavy accent, no patience for crosstalk, no idea what your subject matter actually is — and no way of knowing when it is confidently wrong.

Illustrative examples of documented AI captioning failure modes: unfamiliar terminology, proper names, and missing speaker identification. Note that every error above is fluent, confident, and plausible — which is exactly what makes it dangerous. A reader has no way to tell it is wrong.
How many words actually arrive correctly
Every bar below measures the same thing: the share of spoken words that reach the reader correctly, live, as it is being said. These are not laboratory benchmarks and not polished-afterward transcripts — they are real-time measurements on real lecture audio and real conversations. Longer is better.
Where the averages fall apart
Every accuracy figure ever published assumes a speaker. Your event has a dozen. A commencement has a name reader and four hundred surnames from as many linguistic backgrounds. A seminar has a professor, a guest, and whoever speaks up from the back. The moment the voice changes, the problem resets — and only one of these two notices.
This is the difference the percentages cannot show you. A human captioner is not a transcription rate — they are a listener who adapts, in real time, to whoever is at the microphone. AI applies one fixed model to every voice and degrades silently against the ones it was trained on least. Averages describe a room that does not exist. Precision Captions is hired for the room that does.
Sources: best-case and worst-case AI figures are from an evaluation of eleven commercial ASR services on higher-education lecture recordings. Streaming (live) transcription averaged 10.9% word error versus 9.37% for batch — a statistically significant gap — and individual samples ranged to 53.8% word error. Kuhn et al., Measuring the Accuracy of Automatic Speech Recognition Solutions, ACM Transactions on Accessible Computing, 2024 (arXiv:2408.16287). Dialect figure: average 35% word error rate for Black speakers versus 19% for white speakers across five commercial ASR systems — Koenecke et al., Racial disparities in automated speech recognition, PNAS, 2020 (PNAS). Deaf-speaker figure: 78% word error rate (arXiv:2109.10412). All shown as accuracy equivalents. Human CART accuracy — 121 Captions. RCP-M standard: 97.5% sustained over a 22.5-minute dictation at speeds up to 225 words per minute, with a drop-down rate of five seconds or less — NVRA Certifications.

Specialties
General-purpose captioning handles general-purpose speech. These are the settings that break it — and the ones Precision Captions is built for.
Scripted programs, ceremonies, theatrical productions, and corporate presentations where the words are known in advance. The script is prepared, formatted, and cued ahead of time, then delivered live in perfect sync — with a human ready the moment a speaker departs from the page. Which they always do.
Commencement is unforgiving: hundreds of proper names, many of them uncommon, read at speed, in a room with difficult acoustics, on a day nobody gets to repeat. Name lists are loaded and rehearsed in advance so every graduate’s name appears on screen correctly — the moment it is called.
Captioning a lecture means knowing the vocabulary before the lecture starts. Precision Captions prepares subject-specific terminology for each course and each instructor.
Panels, keynotes, training sessions, and all-hands meetings, captioned remotely. Speaker identification keeps a fast-moving discussion followable, and every attendee can read along on the room screen or on their own device.
Services
Communication Access Realtime Translation, delivered remotely. The spoken word converted to text instantaneously and displayed on a monitor, a personal device, or a large screen for the room.
Captions delivered natively into the platform you already use — Zoom, Microsoft Teams, Webex, Google Meet, and streaming or hybrid setups. No special software required of your audience.
Extensive experience with the One-Cap App and StreamText delivery, so participants can follow captions on their own device, at their own text size, wherever they are seated.
A clean, formatted transcript delivered within two hours of project completion — ready for students, minutes, compliance files, or distribution to attendees.
Agendas, slide decks, name lists, glossaries, and scripts are reviewed and loaded before the event. Preparation is where accuracy actually comes from.
Fully remote captioning for distributed teams, hybrid conferences, and online coursework, with the same certified provider and the same standard of accuracy.
How It Works
Date, duration, setting, platform, and how many people need access. A quote comes back promptly.
Scripts, agendas, slide decks, name lists, reading lists, and any specialized terminology. Everything gets prepared in advance.
On screen in the room, in your meeting platform, or on each participant’s own device via One-Cap or StreamText.
A formatted transcript in your inbox within two hours of the event ending.
About
Precision Captions LLC is the practice of Karen Shipman, a Registered CART Provider – Master, built on a straightforward conviction: people who rely on captions deserve the same quality of information as everyone else in the room. Not the gist. Not most of it. All of it.
The work is credentialed. The Registered CART Provider – Master (RCP-M) certification from the National Verbatim Reporters Association requires sustaining 97.5% accuracy across a 22.5-minute dictation at variable speeds up to 225 words per minute — with a drop-down rate of five seconds or less. It is a demanding standard, and it exists because live access has to be right the first time.
What that certification does not measure is the part clients notice most: arriving prepared, communicating clearly about logistics, sorting out the audio feed before it becomes a problem, and getting the transcript back before anyone has to ask for it. When you hire Precision Captions, Karen is the person captioning your event.
