I run a small dropshipping store on TikTok Shop and my supplier sends me product demos in Chinese—unboxing clips, feature walkthroughs, the whole thing. I used to just add English captions and hope people stuck around, but my watch time was terrible. Last month I tried dubbing one of those videos into English with synced SRT subtitles instead. Took maybe ten minutes. That video hit 340K views in a week and my CPM dropped because people actually watched to the end. Now I'm converting my entire Chinese product catalog this way.
AI recognizes the original speech and translates it, no manual alignment needed.
Subtitles and speech match sentence by sentence, frame-accurate.
Only the speech is replaced — ambient sound and music stay intact.
Local free engines or cloud engines (Whisper, DeepSeek, Kimi and more).
Dubbed video, SRT, VTT or plain text — whatever your workflow needs.
Local mode keeps your files on your computer, never uploaded.
Not in my experience. The AI picks up pacing and tone from the original Chinese audio, so my English dub still feels like a real person hyping up the product. I always preview before posting.
Yeah, that's exactly what I do. The tool separates the voice track from my Chinese supplier videos, swaps in English narration, and leaves the original BGM intact. My unboxing clips still hit the same vibe.
I upload both. Some viewers scroll with sound off, and TikTok's algorithm seems to favor videos with subtitles. The SRT also lets me tweak timing if a product name needs extra emphasis.
SpeakVid uses industry-leading recognition and translation models (Whisper, DeepSeek, Kimi and more), with multi-level fallback to keep output reliable.
Most tasks finish in minutes. A 10-minute video typically completes in 2-5 minutes depending on length and engine.
