Is this Russian speech-to-text really free?

Yes. The page is public, no signup is required, and there are no length limits. The recognition model runs entirely in your browser. For higher accuracy on noisy or accented audio, run your file through Subformer's cloud transcription in Subtitles-only mode.

How does the Russian transcription work in the browser?

It uses an open-source neural speech recognition model, executed by a WebAssembly runtime on your own device. The model (~75 MB) is downloaded on first use and cached in your browser. Subsequent visits skip the download entirely and can transcribe offline.

Is my audio uploaded to a server?

No. Recognition runs locally in your browser. The only network calls are to download the model and the WebAssembly runtime - both are static assets. Your audio file and the generated transcript never leave your device.

What audio formats are supported?

Anything your browser can decode: MP3, WAV, M4A, AAC, FLAC, OGG/Opus, plus video containers like MP4, MOV, and WEBM (the audio track is extracted automatically).

Can I download SRT or VTT subtitles?

Yes. After transcription you can download the result as plain text (.txt), SubRip subtitles (.srt), or WebVTT (.vtt) - both subtitle formats include segment-level timestamps so you can drop them straight into any video editor or player.

Tiny vs Base - which model should I pick?

Tiny (~40 MB) is fastest and great for clean studio audio. Base (~75 MB) is roughly twice as accurate on noisy or accented audio and only slightly slower. If you're not sure, start with Base - it's the default. For the highest accuracy on hard audio (accents, noise, overlap), use Subformer's cloud transcription in Subtitles-only mode.

Does it work offline?

Once the model is cached, yes. The first visit needs network access to download it; after that the page can transcribe audio offline.

Which browsers are supported?

Any modern browser with WebAssembly: Chrome, Firefox, Safari 15+, Edge, and Chromium-based mobile browsers.

Bepul Russian nutqni matnga aylantirish

Русский

Russian formatidagi audio yoki video faylni tashlang va vaqt belgili to'liq transkript oling - bularning barchasi brauzeringizda, ro'yxatdan o'tishsiz. Model bir marta (~75 MB) yuklab olinadi va mahalliy ravishda keshlanadi, shuning uchun keyingi ishga tushirishlar zudlik bilan amalga oshadi va offline rejimda ishlaydi.

Yuqori aniqlik yoki ko'proq tillar kerakmi?

Bulutga asoslangan Russian Nutqni matnga aylantirish

Bepul brauzer ichidagi vosita kichik ochiq kodli modelni ishga tushiradi - toza audio uchun yaxshi, ammo u kuchli Russian aksentlar, shovqin yoki bir-biriga mos keladigan so'zlovchilar bilan kurashishi mumkin va faqat cheklangan tillar to'plamini qamrab oladi. Eshittirish darajasidagi aniqlik, ancha kengroq tilni qo'llab-quvvatlash va SRT/VTT/TXT yuklab olish uchun pullik bulutga asoslangan Nutqni matnga aylantirish xizmatimizdan foydalaning.

Qanday ishlaydi

1. Faylni tashlang
Russian formatidagi har qanday audio yoki video faylni yuklang - MP3, WAV, M4A, MP4 va WEBM barchasi qo'llab-quvvatlanadi.
2. Matnga aylantiring
Birinchi marta bosishda ~75 MB hajmdagi model brauzeringizga yuklanadi. Shundan so'ng tanib olish zudlik bilan va offline rejimda ishlaydi.
3. Yuklab oling
Transkriptni TXT, SRT yoki VTT formatida saqlang. Sizning audiongiz va natija hech qachon qurilmangizni tark etmaydi.

Sizning audio faylingiz qurilmangizda qoladi.

Tanib olish to'liq brauzeringizda WebAssembly yordamida ishlaydi. Tarmoq so'rovlari faqat model va WebAssembly runtime'ni olish uchun bo'ladi - ikkalasi ham ommaviy, statik resurslardir. Biz sizning audiongizni va transkriptni ko'rmaymiz.

Russian transkripsiyasi brauzeringizda qanday ishlaydi

Nutqni aniqlash odatda audiongizni kimningdir GPU'siga yuklashni anglatadi. Bu yerda model buning o'rniga o'z mashinangizda ishlaydi, bu uni bir vaqtning o'zida bepul va shaxsiy qiladi.

Open-source recognition model: Ko'p tilli audio asosida o'qitilgan ochiq kodli neyron model - shuning uchun bitta yuklab olish Russianni tilga xos modelni yuklamasdan boshqaradi.
WebAssembly: Xulosa chiqarish ish vaqti WebAssembly-ga kompilyatsiya qilingan, shuning uchun raqamli kod qumloq tab ichida deyarli mahalliy tezlikda, hech qanday plagin va o'rnatishsiz ishlaydi.
On-device inference: ~75 MB kvantlangan model yuklanadi va dekodlash sikli butunlay mijoz tomonida boshqariladi. Sahifa yuklangandan so'ng, quvur liniyasining hech bir qismi serverga murojaat qilmaydi.
Web Audio API: Faylingiz brauzerning o'z audio quvuri yordamida model kutgan 16 kHz mono formatiga dekodlanadi va qayta namuna olinadi, shuning uchun brauzeringiz o'ynata oladigan har qanday format qabul qilinadi.
