The arithmetic

The Sume public catalog lists Text to speech at $0.0475 per 1,000 characters; ElevenLabs' API pricing page lists $0.04 per 1,000 characters for Flash and Turbo and $0.08 for v2 Multilingual and v3 (both read 2026-10-09). Price is characters divided by 1,000, times the rate.

How to read it

The cheapest line is ElevenLabs Flash. Voices differ per service, so a lower price is only a saving if you accept that voice. Sume reserves the amount from the transcript character count and rounds the reservation up to a whole cent, so the reservation for a very short text is at least one cent.

If your volume is 30,000 characters a month, the monthly gap against ElevenLabs multilingual is $0.97; against Flash it is $0.23 the other way.
