Hearthlen：Win+H 開啟聊天視窗

Win+H Opens the Chat

The capture slider was at 30 dB, a two-second sample peaked at 32768, and “hey Hearthlen” never arrived.

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

The microphone was a square wave

32768 is the top of a 16-bit sample. At that gain the room itself was already clipping, so the wake phrase had no shape left to match. The listener now turns the capture slider down when it is above 60%. After that the meter read 5.25 dB, and the first frames it saw peaked at 977.

The English model also does not hear the made-up name as the spelling. On a clear reading it hears “hey hearth” and “hard one”. Those are the phrases it waits for. Playing “hey hearthlen” through the speakers then logged wake: hey hearthlen.

The window

Win+H opens a window titled Hearthlen chat. A line in that box is the same command the voice path uses. what can you do came back in the window: keyboard and mouse, volume, brightness, find a file, a reminder, and a screenshot. The face in the corner still moves while the reply is spoken, as in Hi, Savindu, and the pointer moved. A message can also be the answer to a question he asked, the way it asked what to type.

The check still open is a person in the room saying the phrase, timed from the first sound to the greeting.
