119 text-to-speech (TTS) models, ordered speed first: the 32 that Coval measures are grouped by speed tier on their P95 time to first audio, then the 87 it does not measure, by name. Voice quality, accuracy and price are compared on each model page; they are never added into one score.
4 models start speaking in 101 ms or less, even on slow turns (P95): Fluxions vui, Alibaba Qwen3 TTS Fast, Inworld Realtime TTS-2 Flash and Gradium TTS.
On slow turns (P95), Fluxions vui is ahead on its own; Alibaba Qwen3 TTS Fast, Inworld Realtime TTS-2 Flash and Gradium TTS are a tie. On typical turns (median), Fluxions vui is ahead on its own; Gradium TTS, Inworld Realtime TTS-2 Flash and Alibaba Qwen3 TTS Fast are a tie. Gaps under 10 ms are treated as ties.
Side by side, with the speed and naturalness frontier: which TTS APIs are fast enough for voice agents.
