"""Run a recognizer using the Google Assistant Library.
|
|
|
|
The Google Assistant Library has direct access to the audio API, so this Python
|
|
code doesn't need to record audio. Hot word detection "OK, Google" is supported.
|
|
|
|
It is available for Raspberry Pi 2/3 only; Pi Zero is not supported.
