The verdict

Deepgram wins, 7.3 to 4.9

Rev AI's cheapest pre-recorded rate is $0.20 an hour, undercutting Deepgram's $0.258. Rev AI does not train its models on what you upload at all, while Deepgram trains on it unless you opt out. Deepgram, though, runs in your own cloud or on premises and sells text to speech as its own standalone API, features Rev AI does not offer. Rev AI transcribes 58 languages to Deepgram's 57.

Pick Deepgram if you need self hosting or standalone text to speech.

Pick Rev AI if you want cheaper pricing and no AI training at all.
