Receive Wakeup keywords from voice assistants such as Google → How to make decisions

If the content of the question is different from the color of the site, I hope that you will let me know the appropriate site.

I'd like to know how you're waiting for Wakeup keywords such as "OK Google!" to be uttered when using voice assistants on your home speaker or smartphone.

If you are constantly monitoring your voice, your electricity consumption will be very high.
However, it didn't happen and I'm waiting.
Also, how do you sort out different words?

I really want to know how voice recognition works, but I'm not good at searching, so I can't find it well.
Thank you for your cooperation

Hello, nice to meet you.

Regarding your question, we are constantly monitoring the audio.So by turning it off, some devices can reduce battery consumption.Think of it as having specialized hardware to do that with low power.(Keyword: Low Power Audio, SOC)

The device simply determines whether the wake-up word matches (even the smartphone that disconnected from the Internet should respond to the wake-up word).Roughly speaking, you can analyze the waveform of the sound and compare it with the sample.(Keywords: Speech Recognition)

The analysis and response of arbitrarily entered speech is much larger, and most of the time it is done on a computer on the Internet.Voice input has been around for a long time, and many of them are processed without a network, but since deep learning, it has been put to practical use, and I think you will often come into contact with online computing resources.
