Background
Inworld built its TTS for game characters and interactive agents, where response time is everything — it posts the fastest warm first-audio on this board. TTS-2 is the current generation.
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).
