Fixing Auto-Captions: 9 Smart Ways to Rescue Butchered Proper Nouns
We’ve all been there. You’ve just finished recording a high-stakes webinar or a heartfelt brand story. You upload it to your favorite platform, click "Generate Auto-Captions," and wait with bated breath. The AI does its thing, and for a second, you’re impressed. Then you see it: your CEO, Mr. Abernathy, has been transcribed as "Mr. A Bear Knappy." Your proprietary software, NexGenith, is now "Next Jen If." And that crucial mention of "Poughkeepsie"? Let’s just say the AI went on a creative journey no one asked for.
It’s a specific kind of cringe that hits you in the gut. On one hand, you’re grateful we don’t have to manually type every word anymore. On the other, these errors make your professional content look like a late-night fever dream. If you’re a startup founder or a growth marketer, these "small" errors aren't just funny—they’re brand-damaging. They scream "I didn’t check my work," and they alienate the very people you’re trying to reach, especially the accessibility-dependent audience who relies on those captions to follow your logic.
The truth is, AI—no matter how much we talk about "neural networks"—doesn’t actually know what a "Poughkeepsie" is. It’s guessing based on phonetics and probability. If your name or brand isn't in its top billion data points, you’re going to get butchered. I’ve spent the last three years obsessing over the bridge between "fast AI" and "perfect editorial," and I’ve learned that fixing this isn't just about clicking "edit." It’s about a strategic workflow that prevents these errors from happening in the first place or wipes them out in seconds rather than hours.
In this guide, we’re going to look at the practical, lived-in reality of fixing auto-captions when proper nouns go off the rails. Whether you’re evaluating a new transcription tool today or trying to save a video that needs to go live in two hours, these frameworks will help you stop the bleeding and get your brand's dignity back.
The Proper Noun Problem: Why AI Hates Your Brand Name
Automatic Speech Recognition (ASR) is a marvel, but it has a "vocabulary ceiling." Most engines are trained on massive datasets—think Wikipedia, news broadcasts, and movie scripts. While that covers general English perfectly, it fails miserably on what we call "Out-of-Vocabulary" (OOV) terms. These include your specific brand name, your team members' names, and industry-specific jargon.
When an AI encounters a word it doesn't recognize, it doesn't just stop. It tries to force that sound into the nearest "known" word. This is why "SaaS" becomes "sass" or "sauce," and why "Kubernetes" often becomes "Cooper Netties." The stakes are high: fixing auto-captions isn't just an aesthetic choice; it's a legal and ethical one. Inaccurate captions can violate accessibility standards (like the ADA in the US or the Equalities Act in the UK), and they certainly don't help your SEO when Google indexes the wrong keywords from your video transcript.
The friction comes from the fact that proper nouns often carry the most weight in your message. They are the who and the what. If the who is wrong, the trust is gone. We need a way to bridge the gap between the speed of AI and the precision of a human editor.
Who This Guide Is For (And Who Should Skip It)
This isn't for the casual TikToker who doesn't mind a few "typos for engagement." This is for the professional operator. Specifically:
- Startup Founders: Who need their proprietary product names to be spelled correctly every single time.
- Growth Marketers: Who are repurposing long-form webinars into "snackable" social clips.
- Consultants & Coaches: Who use specific frameworks or "named" methodologies that AI hasn't learned yet.
- SMB Owners: Who want to look like a million-dollar brand on a thousand-dollar budget.
If you have a 40-hour workweek and only 30 minutes to prep a video for publication, you are in the right place. We aren't going to talk about manual re-typing. We are going to talk about systems.
Strategy 1: Pre-Production Vocabulary Training
The best way to fix a butchered proper noun is to prevent the butcher from showing up. Modern "prosumer" captioning tools like Descript, Rev, or Otter.ai now offer a feature often called "Custom Vocabulary" or "Terminology Lists."
Before you even hit the "Transcribe" button, you can upload a list of words that the AI should watch out for. This changes the probability matrix of the engine. If you tell the AI, "Hey, I’m going to say 'Zylophonic' a lot," it will prioritize that spelling over "Xylophone" or "Silly Phonic."
Pro Tip: Don't just list the word. Many tools allow you to provide "Sounds Like" hints. For a name like "Nguyen," you might add a hint like "Win" to help the AI map the phonetics correctly. This 2-minute setup can save you 2 hours of post-production cleanup.
Strategy 2: The Global 'Find & Replace' Workflow
If the damage is already done, don't go through the captions line by line. That is a recipe for burnout and missed errors. Instead, use a centralized "Transcript View."
Most professional video editors (and even YouTube's built-in editor) allow you to view the full text block. Copy that text into a sophisticated text editor (like VS Code or even a Google Doc) and use the Global Find & Replace function. However, there is a nuance here that most people miss: Case Sensitivity.
AI often gets the word right but the casing wrong. It might say "adidas" instead of "Adidas" or "iphone" instead of "iPhone." When fixing auto-captions, ensure your "Replace" tool is respecting the exact branding. If you use a tool like Descript, they have a "Correct" vs "Overdub" feature. You want to use the "Correct" feature across the whole project to snap every instance of a misspelled name into the right version instantly.
Strategy 3: Solving the Acoustic Paradox
Sometimes the AI fails because the audio is "mushy." We call this the Acoustic Paradox: you want to sound natural and conversational, but the clearer you speak for the AI, the more robotic you sound to the humans.
To fix this without losing your personality, focus on "Consonant Clipping." When you're about to say a proper noun—especially one that starts with a hard consonant like T, K, or P—give it just 5% more "pop." This gives the AI's waveform analyzer a clear start and end point for the word. It's a small physical tweak that results in much higher accuracy out of the gate.
Tool Comparison: Which AI Handles Nouns Best?
Not all transcription engines are created equal. Some use older "Hidden Markov Models," while others use the latest "Transformer-based" architectures. Here is how the big players stack up when it comes to proper noun accuracy.
| Tool / Service | Proper Noun Accuracy | Custom Vocabulary? | Best For |
|---|---|---|---|
| OpenAI Whisper | Very High | Via Prompting | Technical/Niche jargon |
| Rev.ai | High | Yes (Pre-upload) | Interviews & Business |
| YouTube Auto | Moderate | No | High-volume, low-budget |
| Descript | High | Yes | Content Creators |
5 Mistakes That Make Your Captions Worse
- Ignoring the 'Speaker Labels': AI often attributes a proper noun to the wrong person. If Person A says "John Smith" and Person B replies "Yes, John," the AI might spell it "Jon" the second time because it's a different voice profile. Fix speaker labels first; it helps the AI maintain context.
- Over-Editing for Grammar: Captions are a transcript of speech, not a written essay. If you fix every "um" and "uh" while ignoring the fact that your company name is misspelled, you’re prioritizing the wrong thing.
- The "Set and Forget" Fallacy: Just because you uploaded a custom dictionary once doesn't mean it's working for every video. AI models update. Check the first 60 seconds of every video manually.
- Bad Mic Technique: You can have the best AI in the world, but if you're using a laptop mic in a room with an echo, "Microsoft" will become "My Crow Soft" every single time.
- Relying on YouTube's 'Translate' Feature: Never auto-translate butchered proper nouns. You'll end up with a nonsensical word in English being translated into a different nonsensical word in Spanish. Fix the English first.

Frequently Asked Questions
What is the fastest way to fix auto-captions on a long video?
The fastest way is to use a text-based video editor like Descript or Otter. These tools allow you to edit the transcript like a Word document, and the changes automatically reflect in the video captions. Using 'Find & Replace' for common proper noun errors can cut your editing time by 80%.
Can I train YouTube's AI to recognize my name?
Directly, no. YouTube doesn't allow user-submitted custom dictionaries yet. However, uploading a "Correction File" (an SRT or VTT file) allows YouTube's algorithm to learn from your corrections over time, potentially improving accuracy for your specific channel.
Why does the AI capitalize some names but not others?
AI uses "Contextual Probability." If a name is also a common noun (like "Apple" or "Carpenter"), the AI looks at the surrounding words. If the sentence structure suggests a brand or person, it capitalizes. If not, it stays lowercase. This is why "fixing auto-captions" often requires a manual casing check.
How much does it cost to have a human fix my captions?
Professional human transcription (like Rev's human service) typically costs $1.50 per minute. For a 30-minute webinar, that's $45. If your video is for high-ticket sales, this is often the best ROI compared to spending 2 hours of your own time fixing butchered nouns.
Is there a free tool for fixing proper nouns in SRT files?
Yes, Subtitle Edit is a powerful, open-source tool that includes a "Spell Check" and "Multiple Replace" feature specifically designed for proper nouns and common OCR/ASR errors.
Does fixing captions help with Video SEO?
Absolutely. Search engines like Google and YouTube index your caption files. If your primary keyword or brand name is butchered in the captions, you are missing out on search traffic for those exact terms.
Should I remove "ums" and "ahs" from my captions?
For professional commercial content, yes. It makes the text easier to read and allows the viewer to focus on your key proper nouns and data points rather than your vocal tics.
Final Thoughts: Precision Over Speed
We live in an era of "good enough" content, but "good enough" is a dangerous place for a brand to live. When an AI butchers your name, your city, or your product, it creates a micro-flicker of distrust in the viewer's mind. They think, "If they didn't catch this, what else are they missing?"
Fixing auto-captions doesn't have to be a slog. By implementing a custom vocabulary before you record, using global find-and-replace tools, and doing a focused "Proper Noun Pass" before you publish, you can maintain that professional edge without losing your mind. Precision is a form of respect for your audience. It shows you care about the details, and in a crowded market, the details are often the only thing that separates you from the noise.
Ready to elevate your video content? Start by running your last three videos through a "Proper Noun Audit." You might be surprised at what the AI thinks you said. Fix the errors, re-upload the SRT files, and watch your professional credibility (and your SEO) climb.
