The Name It Hears

I said “hey Hearthlen” from the next machine. The ThinkPad microphone recorded it, and the wake listener did nothing.

Savindu Thathsara, savithathsara.me. This is a Hearthlen note from the two computers sitting together.

The old listener was PocketSphinx, waiting for “hey hearth” and “hard one”, because that is what an English dictionary makes of a made-up name. On this recording Whisper heard “Hey, Hertzland.” The keyword list, at its most sensitive setting, scored 0 hits.

The listener now transcribes a short burst and accepts the name as it actually comes out: hearthlin, herthlin, hertzland. The burst that woke it took 340 ms. The log line was wake: hey hearthlen, one second after the phrase ended, and it gave the greeting.
