Voiceover plus captions for a 300-word script: $0.2855
A 300-word script is about 1,800 characters: $0.0855 of text-to-speech plus a $0.20 caption job, $0.2855 on Sume.
Voicing a 300-word script and captioning the result costs about $0.2855 on Sume: $0.0855 for text-to-speech and $0.20 for one caption job.
Text-to-speech is $0.0475 per 1,000 characters, and this estimate assumes 6 characters per word, so about 1,800 characters. The caption price is the fixed per-job rate. Both come from the Sume rate card read on 2026-10-06.
How is the total built?
Two jobs, run in order: audio first, then captions on the finished cut.
| Step | Basis | Price |
|---|---|---|
| Text-to-speech | 1,800 characters | $0.0855 |
| Captions | 1 job | $0.20 |
| Total | about 2 min of speech | $0.2855 |
What should I check?
Add a spare take to the budget if the first read needs a rewrite.
- Count the real characters with
len(text)before you submit. - One text-to-speech request accepts at most 20,000 characters.
- Caption after the final cut, not before.
