Fish Audio API
Pay-as-you-go TTS and voice-cloning API from Fish Audio (S2.1 Pro model), billed per UTF-8 byte with no subscription or minimum.
Billing by UTF-8 byte rather than character makes language the main cost driver: English works out at about $15 per million characters, while Chinese, Japanese and Korean come to about $45. There is no subscription or monthly minimum, and concurrency rises with prepaid spend, from 5 up to 50 at $1,000. The free s2.1-pro-free model carries no latency or DPA guarantees, and no EU region is documented.
