Our take: Fish Audio suits creators who need voiceovers and developers building voice apps, with a free tier of 8,000 credits per month and paid plans from $15 monthly or $11 per month billed annually.
Main limitation: The Free tier is capped at 8,000 credits, 7 minutes and 500 characters per generation, and its commercial-use terms are inconsistent on the pricing page.
