8 models were tested in Filipino by Artificial Analysis or Speko. 4 of the 8 are in the multilingual speed ranking; the others are not tagged multilingual by Coval or are not measured by it. The fastest ranked model tested in Filipino is Inworld Realtime TTS-2.

No public source publishes naturalness or accuracy for Filipino on its own, and all latency is measured in English from the US East. The page therefore says who was tested in Filipino, and how fast each model is in general.

How the rows are ordered. Ranked models first, in ranking order (speed tier, then P95, ties by median); the 4 models without a rank follow alphabetically.
