The old way is slow and expensive

Manual translation, hired voice actors, days of waiting. Creators and teams lose time and money on every single video.

Skip the old workflow

Waiting days for a manual translation while your audience loses interest?

Paying an agency for every single video, no matter how short?

Machine-translated subtitles full of errors and misaligned timing?

Worried about uploading your content to unknown websites?

How It Works

Done in four simple steps

Upload, pick languages, and let the AI handle the rest. No software to install.

01

A few clicks, that is all.

02

Choose source and target language

A few clicks, that is all.

03

AI translates and dubs automatically

A few clicks, that is all.

04

Export dubbed video or SRT subtitles

A few clicks, that is all.

I run a small YouTube channel teaching watercolor techniques, and last year a subscriber sent me a 12-part course from Bilibili—entirely in Chinese. I wanted to adapt it for my English-speaking audience, but hiring translators for 8 hours of content would've cost me around $2,400. I started looking for a way to translate Chinese online courses to English free, found this tool, and uploaded my first SRT file on a Tuesday afternoon. By Wednesday morning I had a full English transcript, timed perfectly to the original video. I've since converted three more courses into VTT format for my website and TXT summaries for my newsletter. The free tier handled everything I needed for my first two projects.

FAQ

Common questions

Will the translated subtitles keep the original timing for my course videos?+

Yes. The tool preserves exact timestamps from your uploaded SRT or VTT file, so English subtitles appear at the same moments as the original Chinese audio—crucial when you're explaining step-by-step techniques.

Can I export just a plain text transcript instead of subtitles?+

Absolutely. I often download TXT files to create blog posts or course worksheets from my translated content, stripping out timestamps entirely while keeping the full lesson structure intact.

How accurate is the translation for specialized terms in my niche?+

For my watercolor course, terms like 'wet-on-wet' and 'dry brush' translated correctly. I'd recommend spot-checking technical vocabulary in your field, but I rarely need more than minor tweaks.

How accurate is the AI result?+

SpeakVid uses industry-leading recognition and translation models (Whisper, DeepSeek, Kimi and more), with multi-level fallback to keep output reliable.

How long does it take to translate chinese online courses to english?+

Most tasks finish in minutes. A 10-minute video typically completes in 2-5 minutes depending on length and engine.
