English and Sinhala

The Sinhala voice said "ආයුබෝවන්. මම හර්ත්ලන්." Inference took 112 milliseconds. The greeting itself was 2.04 seconds of audio.

English was the only filled-in language. Sinhala was an empty row in the same manifest. That row now points at a real voice, si_LK-sinhala-medium, and both languages share one multilingual speech model. The wake phrase is still "hey Hearthlen". After it, a sentence in Sinhala script is answered in Sinhala and spoken with that voice. English still uses the Lessac voice.

Asked "ආයුබෝවන්. ඔයා කොහොමද?", Qwen2.5-3B answered in Sinhala script in 9564 ms. The sentence is rough. It is Sinhala, which is what the voice speaks. The dashboard shows EN and සිංහල, and the one just heard is the bright label. The window those labels sit on is the dashboard.
