Computer-aided transcription software, known in the court reporting field as CAT software, is the program that converts the phonetic key-chords a stenographer types on a stenotype machine into readable English text, usually within milliseconds of each keystroke. Federal law requires court proceedings to be recorded verbatim, and CAT software is what makes that possible at the speed of live speech.1Office of the Law Revision Counsel. 28 USC 753 – Reporters Beyond the live translation, it also streams a rough draft to the judge and attorneys during the proceeding, provides the editing tools the reporter uses afterward, and produces the certified transcript that becomes the official record.
How the Translation Engine Works
At its core, CAT software is a matching engine. When the reporter presses a combination of keys on the stenotype, the software looks up that chord in a hierarchy of dictionaries. It checks the reporter’s personal dictionary first, where years of custom shortcuts live, then falls back to a larger main dictionary shipped by the developer. Specialized sub-dictionaries for legal and medical terminology sit in the chain too, so words like “defibrillation” or “indemnification” translate correctly without the reporter having to finger-spell them.
The personal dictionary is where reporters put the most work outside actual proceedings. Each reporter learned a steno theory in school that maps English sounds and words to specific key combinations, and their personal dictionary grows out of that foundation over the course of a career. The goal is to drive down the number of untranslated strokes to as close to zero as possible.
Conflicts happen constantly during live writing. A single chord might match “there,” “their,” or “they’re,” and the software has to pick one. Modern translation engines use context-based algorithms to choose the likeliest option, and when the ambiguity can’t be resolved automatically, the entry is flagged for the reporter to fix later. The same logic handles punctuation placement, capitalization after periods, and paragraph breaks. Reporters writing at 225 words per minute or more depend on these automated decisions being right the vast majority of the time, because stopping to correct an error mid-testimony means falling behind.
Realtime Output During Proceedings
Realtime is the feature that turned court reporting from a behind-the-scenes record-keeping job into an active part of how trials are conducted. As the reporter writes, the translated text streams to external screens, laptops, or tablets used by the judge, attorneys, and other participants. In the courtroom the connection usually runs through a USB cable or a secure local wireless network. Remote participants can view the feed over encrypted internet connections, which became standard practice after the shift toward hybrid proceedings.
Federal regulations under the Americans with Disabilities Act specifically list “real-time computer-aided transcription services” as an approved auxiliary aid for people who are deaf or hard of hearing.2eCFR. 28 CFR 35.104 – Definitions State and local government entities, along with businesses open to the public, must provide effective communication accommodations, and realtime transcription is one of the recognized methods.3ADA.gov. ADA Requirements: Effective Communication Outside the accommodation context, judges use the live feed to check exact phrasing when ruling on objections, and attorneys use it to track testimony without relying on memory.
The text that appears during a realtime feed is a rough draft, not the official record. Federal judiciary policy is explicit on this point: a realtime translation does not satisfy the requirement for a certified transcript and cannot be relied upon for verbatim citation on appeal.4Guide to Judiciary Policy. Guide to Judiciary Policy Vol 6 Court Reporting Attorneys who want live access pay per-page fees. The Judicial Conference caps federal court rates at $3.70 per page for a single feed, $2.55 per page when two to four parties share it, and $1.80 per page for five or more feeds.5United States Courts. Federal Court Reporting Program State courts and private depositions set their own rates.
Providing realtime services in federal court generally requires the Certified Realtime Reporter credential from the National Court Reporters Association. Earning it means passing a five-minute testimony test at 200 words per minute with at least 96 percent accuracy, and the transcript cannot be edited before submission.6NCRA. Certified Realtime Reporter (CRR) Hitting that threshold on an unedited translation is what separates a well-tuned personal dictionary from one that still needs work.
Editing After the Proceeding
When the proceeding ends, the reporter’s job shifts from writing to editing. The rough translation always contains errors — untranslated strokes, misresolved homophones, missing punctuation — and the software provides a set of tools built specifically to clean them up.
AudioSync is the most valuable of these. The software records digital audio alongside the steno notes and links each segment of audio to the corresponding line of text. Clicking any word plays back the exact moment it was spoken. When two attorneys talk over each other or a witness mumbles, this is how reporters verify what was actually said rather than guessing from a garbled outline.
Globaling lets a reporter fix a recurring error across the entire document with one command. If the personal dictionary mistranslated “plaintiff” in 47 places, a single global edit corrects all 47 at once. Automated formatting tools then apply the margins, line numbering, page headers, and other layout requirements that court rules demand, sparing the reporter from manual page setup on transcripts that can run hundreds of pages.
Many reporters hire a scopist to handle the bulk of the editing. A scopist is a trained professional who works inside the CAT software, listening to the audio, correcting translation errors, fixing punctuation, and making the document read consistently. Most of the post-proceeding labor lives here; a scopist might spend three to four hours editing a transcript from a one-hour hearing.
Certifying and Delivering the Transcript
Once editing is complete, the reporter certifies the transcript. Certification is an official attestation that the document is a true and correct record of the proceedings. Under federal law, only the reporter or designated individual who recorded the proceeding can sign this certification, and the certified transcript is treated as prima facie evidence of what happened.1Office of the Law Revision Counsel. 28 USC 753 – Reporters
Certification is increasingly applied digitally rather than with a wet signature on paper. The technology typically uses a digital certificate from an approved certificate authority such as DigiCert, Entrust, or GlobalSign, embedded in a PDF or a proprietary e-transcript file. The reporter’s scanned handwritten signature is included alongside a timestamp. Only the certifying reporter can apply the signature; delegating it to a firm or another person is prohibited in jurisdictions that have adopted digital signature standards.
Judicial Conference policy allows certified transcripts to be delivered as PDFs, ASCII text, or any other format the ordering party requests and the reporter agrees to.4Guide to Judiciary Policy. Guide to Judiciary Policy Vol 6 Court Reporting The electronic file cannot contain copy protection or programming codes that would prevent the purchaser from copying or transferring the data. Reporters who assume they can lock down their work product are sometimes surprised by this rule.
The Main Software Options
Three products dominate the CAT software market. The choice among them often comes down to what a reporter learned in school, because switching means rebuilding years of dictionary and workflow habits.
- Case CATalyst from Stenograph is the most widely used. A professional license costs $4,299 and includes starter dictionaries, video training, and one year of technical support. The license covers non-simultaneous use on up to four computers, so a reporter can install it on both a courtroom laptop and a home workstation. Ongoing support and updates after the first year require a paid renewal.7Stenograph. Case CATalyst Pro
- Eclipse from Advantage Software is priced at $4,499 for the professional steno edition, with annual support running $799 for updates and 24/7 technical assistance. The student version comes with an unusual incentive: on graduation, 100 percent of payments made toward the student software, plus a $300 bonus, is credited toward the professional edition, up to a $650 discount if purchased within 120 days of graduation.8Advantage Software. Anytime Support 24/79Advantage Software. Student Software – Steno/Voice
- ProCAT Winner uses a subscription model instead of a large upfront purchase. The annual fee is $708, with a one-time $495 setup fee that covers dictionary conversion and training for reporters switching from another platform. The subscription includes the full feature set, though cumulative cost overtakes the one-time purchase models after several years.10ProCAT. ProCAT Winner Steno Edition – Subscription
All three handle the core functions: translation, realtime output, AudioSync, globaling, and formatting. Their interfaces and dictionary management tools differ enough that reporters develop strong preferences. Switching mid-career is possible, since transcript files and dictionaries can usually be imported, but it’s disruptive enough that most reporters avoid it.
Hardware the Software Needs
CAT software is computationally demanding because it processes steno input, runs the translation engine, records audio, and often streams realtime output all at once. Underpowered hardware introduces latency, and even a fraction of a second between a keystroke and the translated word appearing on screen can throw off a reporter working at full speed.
Case CATalyst requires Windows 11, an Intel Core 5 or 7 or AMD Ryzen 5, 7, or 9 processor, at least 8 GB of RAM, and a 256 GB hard drive.11Stenograph. System Requirements for CATalyst One important caveat: ARM-based processors, commonly branded as Snapdragon in Windows laptops, are not compatible because of driver issues. That’s an easy trap as more manufacturers ship ARM machines. Eclipse recommends heavier hardware, an Intel i5 or better at 3.0 GHz with 16 GB of RAM minimum, and requires a solid-state drive rather than treating it as optional.12Advantage Software. Hardware Recommendations Reporters using Eclipse’s voice-writing or speech recognition features need more still: an Intel i7 or AMD Ryzen 7, 32 GB of RAM, and a 500 GB SSD at minimum.
The stenotype machine connects to the computer through USB or Bluetooth. Most professional setups include a secondary backup computer running in parallel, capturing the same steno output independently, so a mid-proceeding crash doesn’t lose the record. A hardware failure during trial with no backup can result in a mistrial.
Cloud backup adds another layer of protection. Stenograph’s cloud service for CATalyst compresses and encrypts files for HIPAA-compliant storage and includes 100 GB of free capacity. The backup pauses automatically during realtime writing and active editing so it doesn’t compete for system resources when performance matters most.13Stenograph. Cloud Backup
Ongoing Costs That Come With It
The sticker price of the software is just the beginning. Annual support contracts are effectively mandatory, because skipping them means losing access to updates and technical support, and updates often include critical dictionary improvements and compatibility fixes for new operating systems. Eclipse’s annual support renewal runs $799 for the standard steno edition.8Advantage Software. Anytime Support 24/7 ProCAT bundles updates into its $708 annual subscription. Stenograph’s EDGE program for CATalyst bundles support, updates, and cloud backup at a cost that varies depending on how many versions behind a reporter has fallen.
Scopist fees add up quickly for reporters with heavy caseloads. Rates typically fall around $1.00 to $1.50 per page, so a 300-page transcript can mean $300 to $450 out of pocket before the reporter has earned anything from the job. Proofreaders, if used separately, charge roughly $0.30 to $0.50 per page on top of that.
Then there’s the stenotype machine itself, typically $3,000 to $5,000 for a professional model, plus the backup laptop, digital signature certificates, professional association dues, and continuing education to maintain certifications. CAT software isn’t a standalone purchase. It’s the centerpiece of an ecosystem that only works when everything around it is maintained.
