Visitors then see a subtitles button on the video player. The speech-to-text runs **in the browser**, on the machine of whoever pressed the button. Not on your server, and not on anyone’s API. That single decision is what this plugin is, and everything below follows from it. #### Nothing leaves the computer There are two ways to turn speech into text: send the audio somewhere and get the words back, or run the model where the audio already is. This plugin does the second. For a marketing clip either way is fine. For patient education, legal recordings, internal training, HR material or paid membership content, sending the file to a third party is often the difference between _allowed_ and _not allowed. The browser reads the file, works on it, and writes the result back. The only thing that ever downloads is the speech model itself, once. #### No account, no key, no bill * **Nothing to sign up for.** No OpenAI account, no API key to create, store, rotate or explain to a client. * **No per-minute charge.** Transcription services meter audio by the minute. Nothing here is metered — caption the same course twice, or a hundred hours of it, and the cost does not change. * **No server load.** Your host never transcodes or transcribes anything, so this runs on the cheapest shared hosting without a queue, a cron job or a worker process. #### How it works 1. Go to **Media > Bharti Subtitles**, choose a video and the spoken language, press ** Generate subtitles** 2. Watch the lines appear, then fix anything the model misheard — names and technical words are usually where it slips 3. Press **Save to this video**. The `.vtt` is written beside the video and attached to it Or download `.srt` / `.vtt` instead and take it to YouTube, Vimeo or a video editor. #### What you get * 17 languages, including **Hindi, Marathi and Hinglish** written in Roman script * Every line editable before you save * Works with the Gutenberg **Video** block and the classic `[video]` shortcode * Control how the subtitles look — font, size, bold, capitals, colour, background and opacity, shadow, position and alignment — with a live preview * Translation ready, with a `.pot` file included #### Accessibility Captions for prerecorded video are a WCAG 2.1 requirement (Success Criterion 1.2.2). If your site has an accessibility obligation, this is one of the items on the list. #### Honest limits Most of this would normally be left out of a plugin page. It is here because the wrong expectation wastes your time and mine. * **The first run downloads the speech model** — about 50 MB for most languages, about 250 MB for Hindi, Marathi and Hinglish, which need a larger one. The browser keeps it, so it is once per machine, not once per video. * **Speed depends on the machine, not the hosting.** A modern laptop manages roughly real time or better. An old one will be slower. * **No bulk or overnight processing.** One video at a time, with a browser tab open. Doing it in bulk would mean a server doing the work, and then the zero cost and the privacy both disappear. * **Hindi, Marathi and Hinglish need more correcting than English.** The model has seen far less of them. What you get is a usable draft to fix, which is much faster than typing from nothing — but it is a draft, and the panel says so before you press the button. * **The video must be one your browser can play.** MP4 (H.264 + AAC) and WebM are safest. HEVC inside a `.mov` will not decode. #### What it needs * A current version of Chrome, Edge, Firefox or Safari * An internet connection the first time, to download the speech model * A writable uploads folder — the `.vtt` is saved beside the video ### Source code and build The two files in `assets/js/` are built, not written by hand. Their complete source ships inside this plugin so nothing needs to be taken on trust: * `src/` — all of the TypeScript and React that becomes them * `package.json`, `tsconfig.json`, `vite.config.ts`, `vite.worker.config.ts` — the build configuration To rebuild from that source: ``` npm install npm run build ``` which regenerates `assets/js/subtitles.js` and assets/js/transcribe-worker.js exactly as shipped. #### Third-party code Bundled into those two files by the build, both unmodified: * **React** 18.3 — https://github.com/facebook/react — MIT * **Transformers.js** 3.8.1 — https://github.com/huggingface/transformers.js — Apache-2.0 ### External services Two things are downloaded into the browser the first time you generate subtitles, and then kept by the browser’s cache. Nothing is uploaded, no account is needed, and no key is required. #### The speech engine * **What:** ONNX Runtime Web, the WebAssembly engine that runs the model. Part of Transformers.js, pinned to version 3.8.1. * **Server:** jsDelivr — `https://cdn.jsdelivr.net/npm/@huggingface/transformers@ 3.8.1/dist/` * **When:** the first time you press Generate subtitles, once per browser. * **Sent:** nothing. It is a download. #### The speech model * **What:** an OpenAI Whisper model, converted for the browser. About 50 MB for most languages, about 250 MB for Hindi, Marathi and Hinglish. * **Server:** Hugging Face — `https://huggingface.co/` * **When:** the first time you use a given language, once per browser. * **Sent:** nothing. It is a download. Your video is never sent to either of them, or to anywhere else. It is read from your own Media Library by your own browser and worked on there. Terms and privacy: jsDelivr — https://www.jsdelivr.com/terms and https://www.jsdelivr. com/terms/privacy-policy-jsdelivr-net · Hugging Face — https://huggingface.co/terms- of-service and https://huggingface.co/privacy #### Serving them yourself If your site cannot reach an outside server — some government, medical and internal deployments cannot, and jsDelivr is blocked in some countries — put the files on your own host and point the plugin at them: ``` add_filter( 'bharti_subtitles_wasm_paths', function () { return 'https://example.com/onnx/'; } ); ``` The files to copy are the contents of `@huggingface/transformers@3.8.1/dist/`. The model can be self-hosted the same way; see the Transformers.js documentation for `env.remoteHost`. Be honest with yourself about this before installing: if the first run cannot reach these two servers, the plugin cannot generate subtitles. After that first run it works offline. ## Screenshots [⌊Media > Bharti Subtitles: pick a video and a language.⌉⌊Media > Bharti Subtitles: pick a video and a language.⌉[ Media > Bharti Subtitles: pick a video and a language.

Upload the plugin folder to `/wp-content/plugins/`, or install the ZIP through ** Plugins > Add New > Upload Plugin**. 2. Activate it. 3. Go to **Media > Bharti Subtitles**. 4. Pick a video, pick the spoken language, press **Generate subtitles**. 5. Check the lines, fix anything the model misheard, then **Save to this video**. Defaults live under **Settings > Bharti Subtitles**. ## FAQ ### Do I need an OpenAI key or any other account? No. Nothing is sent to any API. The model runs inside your own browser. ### Is my video uploaded anywhere? No. The browser reads the file straight from your own Media Library and works on it locally. The only thing downloaded is the speech model itself, once. ### Why is the first run slow? The speech model has to be downloaded the first time — about 50 MB for most languages, about 250 MB for Hindi, Marathi and Hinglish, which need a larger one. After that the browser has it and there is no wait. Transcription speed then depends on the machine, not on your hosting — a modern laptop does roughly real time or better. ### Can I run it on the server instead, or in bulk overnight? Not in this version. Everything is deliberately in the browser, which is what keeps the cost at zero and the video private. Bulk generation would mean a server doing the work, and that means both of those go away. ### The subtitles do not show on the front end. Check three things: the video has subtitles saved (Media > Bharti Subtitles will say so), **Settings > Bharti Subtitles > “Automatically show subtitles”** is on, and your theme is not replacing the video player with its own. If it is, turn the setting off and add the track yourself. ### The subtitles show, but there is no CC button. The Video block has **Playback controls** switched off, so the player draws no controls at all. Select the video in the editor and turn that setting on. Nothing is wrong with the subtitles — they are attached, which is why they appear on screen. ### It says the browser could not read the audio. The video is in a codec your browser will not decode — usually HEVC inside a .mov. Convert it to MP4 (H.264 + AAC), re-upload, and it will work. ### Which languages work? English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Polish, Japanese, Korean, Chinese, Turkish and Indonesian are the strong ones. Hindi, Marathi and Hinglish also work, with two honest caveats below. Only languages the on-device model actually handles are offered — listing more would just produce bad subtitles. ### What is different about Hindi, Marathi and Hinglish? Two things, and the panel tells you both before you press the button. They need the larger speech model — about 250 MB instead of 50 MB, and slower to run. The smaller model does not write these languages down at all: it turns Hindi into English and Marathi into Roman letters, so the size buys the script itself. And be realistic about the accuracy. The model has seen far less of these languages than of English, and on a Marathi test most lines came back with the script correct but the words wrong — close enough to recognise what was said, not close enough to publish. Expect to rewrite most of them. What is reliably right is the timing. The tedious half of subtitling is deciding which line shows when, and that comes out correct: fourteen cues, each three or four seconds, following the speech. Retyping the words into a finished set of cues is still much faster than building the whole thing from nothing — but that is what you are getting, not a draft you lightly correct. English and the European languages do not have this problem. ### Does it work on mobile? The panel is for site owners, so it is built for a desktop browser. The subtitles it produces show on every device, mobile included. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Bharti Subtitles” is open source software.
