Google TTS APIs in 2026: 7 models, speed tier and languages
Google has 7 models in the database. 1 of the 7 are in the multilingual speed ranking; the others are not tagged multilingual by Coval or are not measured by it.
Every measure is copied from a public benchmark with its source on the model page; a measure no benchmark holds is shown as n/a, never estimated.
How the rows are ordered. Ranked models first, in ranking order (speed tier, then P95, ties by median); the 6 models without a rank follow alphabetically.
