A Conversation, Then the Work

The wake word answered once and then went quiet. A person does not talk to a command line.

Savindu Thathsara, savithathsara.me. This is a Hearthlen note from the ThinkPad.

After "hey Hearthlen" the microphone stays open. Three agents share the sentence. The voice agent talks, and the small model stays loaded so the next reply does not pay for another startup. The device agent handles the volume, the brightness, files, reminders, and Wi-Fi. The desk agent takes the sentences that start work, create, open, write, and the rest, and it uses the keyboard and mouse on a background thread. The voice says it will do that, and it keeps listening. Eight quiet seconds ends the session.

The voice agent, already loaded, answered three different sentences on the laptop. "how are you" came back in 437 ms. "what should we do today" came back in 356 ms. "tell me a short joke" came back in 346 ms. A recording of the wake phrase from this desk scored 0.25, so that pass never opened the session.

The previous ear is in the wake word trained on this Mac.
