Background
Gradium is a smaller European vendor that versions its TTS in place — the June 2026 refresh improved prosody and pacing under the same model id. A new entrant here: its live standing is still settling.
On the board
Live results — the numbers move as votes land. Latency is measured at the Speko gateway (warm first-audio, n=30); price is the provider's published rate. Method details on the methodology page; raw standings as open data (CC BY 4.0).
