I use different names for my various Alexa Echo devices, but it reminds me of my mom growing up 50+ years ago: She sometimes had to go down the list of names for all four of us siblings before she got the correct name to yell at us for doing something stupid!
I have several Siri capable devices, but just like with the Echo devices, I much prefer to use my iPhone XR or iPads to activate them to do something. Voice should be quicker, but it typically isn't and it is often misinterpreted by the devices. And if I get really mad and call Alexa a dirty name, I get back a lot of attitude. To be honest, I've turned of the microphones on most of my Echos, and I leave Siri disabled on my iThingies. Voice control just isn't that good yet.
My new Sony 4K TV has built in Android TV with voice control. I haven’t tried it yet to see if it is just as bad or perhaps a little better. However, like I stated above, I find using my iPad to search for interesting shows and movies via apps like Netflix, Philo, OTA TV, YouTube, etc. is way faster and easier than trying to get to them via voce control on any device. This includes the Fire TVs and TVs. Chances are high that voice control will screw up the commands and open the wrong app or channel or show or open it on the wrong device.
Getting the right version of a song is nearly impossible with voice control too.
