Voiceover plus captions on Sume: cost by script length

Voicing a script and captioning the result is two charges on Sume: text-to-speech, priced by the length of the script, and one caption job at a fixed price. The total grows with the script; the table gives it for every script length these posts priced.

Worked example: Voiceover plus captions for a 1200-word script: $0.5420

Voicing a 1200-word script and captioning the result costs about $0.5420 on Sume: $0.3420 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 7,200 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.

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.
