AI Subtitling & Captioning Services

We give you accurate, AI-generated subtitles and captions that land perfectly in over 125 languages. They’ll improve your accessibility and even boost your SEO reach - all without the week-long back-and-forth you’re used to.

What Are AI Subtitling & Captioning Services?

Depending on the platform you’re on, you’re dealing with six-second attention spans that leave you no room for guesswork. If the on-screen text disappears too soon or if your translations aren’t accurate, your audience is going to swipe away!

Our AI subtitling and captioning services fix that by:

Listening to your video

Turning speech into text instantly and accurately

Lining every character up to the millisecond

Adding captioning so you also capture ambient sounds (door slams, music cues)

Our AI engine does the heavy lifting here, while our Audiovisual linguists jump in to make sure tricky idioms are accurately written - no bad translations that don't highlight the content properly. This gives your videos a much more native and inclusive feel, from Buenos Aires to Bangkok!

Why Are Quality AI Subtitles and Captions So Important?

A single typo in one of your subtitles - especially if it’s due to an incorrect translation into a different language - can have an impact on your credibility. We want your viewers to stay glued to the screen through these services:

Subtitle localization - culturally tuned translations that keep all the same humor and brand voice.

Multilingual closed captions - ADA-compliant text that describes both the dialogue and on-screen sounds.

Website localization - sync captions to any embedded mini-players you have so your visitors spend more time on the site.

SEO-rich transcripts - search engines index every spoken word, which means better discoverability for podcasts or webinars, for example.

Streaming-platform formatting - SRT, VTT, SCC, you name it, delivered ready for instant upload.

We want you to have a single partner who handles everything from the first frame to the final file with Day Translations!

Subtitles vs. Closed Captions - Which Do You Need?

Subtitles assume the viewer can hear but might not understand the language, so they translate spoken dialogue only. Closed captions, on the other hand, cater more to deaf and hard-of-hearing audiences because they show non-speech elements like “[applause]” or “[dramatic music fades].”

We’re seeing platforms such as Netflix and YouTube now prioritizing accessibility compliance, so most clients order both in one go. We generate the transcript once, then spin out separate subtitle and caption tracks!

Types of AI-Subtitling We Offer

We’re not just lazily asking AI to simply listen on behalf of our team - we go far more in depth than that:

Auto-Transcription

Learn a bit more about our process:

Quick speech-to-text - Our engine identifies accents and background noise so we can nail down the first draft faster.
Speaker separation - Multi-voice scenes are still clear since they come with automatic labels that you can tweak.
Timecode accuracy - Lines snap to frames, so lips and text stay in sync even at split-second cuts.

We still provide that human touch to make sure everything’s accurate, but as you can see, our tools do a lot of the heavy lifting.

Translation & Localization

Got a specific country you’re trying to branch out into?

125-language coverage - From widely spoken languages like Spanish to niche dialects like Yoruba.
Cultural adaptation - Idioms and brand taglines have the same sentiment and impact across markets.
SEO infusion - Keywords get woven into the transcripts, so this helps search engines find your multilingual content.

We can still provide English subtitles, but you can really start scaling once you take advantage of our multilingual capabilities.

Human QA & Styling

What else do we do to make sure your final product is accurate in every sense?

Readable line breaks - Expect character limits so that everything reads seamlessly.
Accessibility checks - Details like the color-contrast and caption placement all follow WCAG and FCC guidelines.
Platform packaging - You can get your subtitles in any format from Netflix-TTML to YouTube-SRT.

And because our AI tools are so effective, we can usually guarantee you same-day results, depending on the length of your content.

Our Proven AI Subtitling Process

Take a look at how we go from the initial chat to perfect subtitles and captions every time:

Step 1: Discovery & Keyword Mapping

We chat about everything from audience personas and target keywords to distribution channels, so we know our subtitles will match your accessibility and SEO goals.

Step 2: Project Blueprint

You get a clear brief that talks about language pairs and file specs. We also touch on style guides and milestones, so there aren’t any surprises down the line.

Step 3: AI Generation + Linguist Review

The system whips up a transcript and aligns all the timecodes, then our subtitlers refine the pacing and terminology.

Step 4: Collaborative Feedback

Make various edits if you want something changed. Want a slower reading speed or different line breaks? Let us know, and we’ll iterate in hours instead of days.

Step 5: Final QC & Delivery

We run automated validation plus a few human spot-checks. After we embed the metadata, we hand you zipped subtitle packages and SEO-friendly transcripts that are ready to publish!

FAQs

Got more questions about how our AI subtitling & captioning process works?
You can get in touch with our team to learn more, or keep reading to see if we answered it here:

How accurate are your AI subtitles?

Initial AI drafts are highly accurate, just like the rest of our AI services. Our human review then pushes that even further, where we catch context-specific phrasing and on-screen timing glitches.

Can you generate subtitles in real time for livestreams?

Yes! This makes it ideal for webinars or any other kind of livestream.

What subtitle formats do you deliver?

We support SRT, VTT, SCC, TTML, STL, and custom XML. Just tell us where you’re publishing, and we’ll package files to spec.

Will subtitles improve my video SEO?

Definitely, because search engines crawl the text track, which will help your content rank for spoken keywords and appear in “featured snippet” results.

How quickly can I get multilingual subtitles for a 30-minute video?

English master subtitles can be ready the same business day, while other languages usually require just a little bit extra (and it depends on review cycles), so that we can make sure any slang or cultural idioms used are properly carried over.
