The Name It Hears

Описание и применение

НовыйListener принимает произнесенную форму имени Hearthlen и разбужается за 340 мс с лог-строкой 'wake: hey hearthlen', тогда как PocketSphinx не распознал это имя.

Задача

A wake-word listener built on PocketSphinx failed to recognize a made-up name spoken aloud, while Whisper recognized the same phrase as 'Hey, Hertzland.'

Результат

The new listener transcribes a short burst and accepts the spoken name as it comes out, waking in 340 ms with the log line 'wake: hey hearthlen' and delivering the greeting, whereas the PocketSphinx-based listener failed to recognize the made-up name.

Рабочий процесс

• Record a short spoken burst containing the made-up name 'Hearthlen' using the ThinkPad microphone.
• Run the new listener that transcribes the burst and accepts the actual spoken form of the name.
• Verify the wake event fires within 340 ms and produces the log line 'wake: hey hearthlen' one second after the phrase ends.
• Confirm the greeting is delivered.

Доказательства

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

Источник

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.

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.
