The Name It Hears

说明与用途

新的监听器将短语音burst转录并接受实际说出形式的名称，在340毫秒内唤醒，日志行显示为'wake: hey hearthlen'，并发出问候，而基于PocketSphinx的旧监听器未能识别该虚构名称。

问题

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.'

结果

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.

工作流

• 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.

证据

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

来源

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.
