Hey @Simon144
On the website they state the following:
What's considered a security camera or a recording device
Any mechanism that can be used to capture or transmit audio, video, or still images is subject to these rules. This includes, but is not limited to, things like wifi cameras (for example, Nest Cam or Dropcam), nanny cameras, web cameras in computer monitors, baby monitors, mounted or installed surveillance systems, decibel and device monitors, and smart phones with video and/or audio recording capabilities.
Based on their definition, I would not include Google Home or Alexa device in there.
I also had a guest accuse me of having a recording device, when it was an iHome thermostat reader LOL... You will most likely be fine
