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 150,000 characters a month, the monthly gap against ElevenLabs multilingual is $4.88; against Flash it is $1.13 the other way.
