How is AI voiceover priced—per character or per minute?
AnswerAI voiceover is billed by character, not by clip length. In Dianwu each workspace gets 30k free characters a week, reset Monday 00:00 Shanghai time. After that you pay $0.361 per 10k characters from wallet balance. One run accepts at most 4000 characters. How the weekly pool works is in How many free voiceover characters do you get each week?. Count the copy. Do not estimate from duration.
Why characters, not minutes
The same line can last 8 seconds or 14 if you change speed. Minute pricing charges you for pauses. Character pricing matches what you pasted, and the quote shows before you synthesize.
The dubbing page shows free characters used this run, paid characters, and the wallet debit. Inside the weekly cap, you pay nothing.
Weekly cap and overage
The free pool is per workspace, not per seat or per clip. Synthesized characters add up until 30k. Overage is $0.361 per 10k, taken from balance. The weekly meter is in How many free voiceover characters do you get each week?.
A single run stops at 4000 characters. Split a long script. Extra whitespace collapses before the count.
Versus hiring a voice actor
Talent is usually priced per spot or per minute, and a rewrite often bills again. AI resynthesis only adds characters.
Use it for explainers, narration, and dialogue you will revise. Keep human talent for performance-heavy spots—see AI voiceover vs a voice actor—what actually changes?. Dianwu puts dubbing on the same factory line as writing and video.

Short answers
- Can I synthesize without signing in?
- Dubbing lives in the signed-in workspace. This page explains the price. To hear audio, register and open dubbing.
