And if it's anything like siri, it can barely do anything useful, so it doesn't matter if it understands you.

"I searched the web for 'shutup stop mute stop talking' and here is what I found on Wikipedia..."

I find Siri really useful - for a very limited set of tasks where recognition is about 100% and being hands free has a benefit. Typically this is starting exercise workouts and countdown timers. For more general tasks the recognition is still good (for me, seems to cary by voice) but even at 90% there will be one mistakes in most requests.

counter point, I use my alexa daily and don't run into many issues with voice recognition, or it's lack of understanding.

Daily uses:

1) in the AM i set up all my needed reminders for 5 minutes before every meeting I have

2) it's connected to my hue bridge so I can turn off/on lights by asking while laying in bed, which is wonderful.

3) I play music all day.

4) It reminds me 10 minutes before every sunset to go outside for a walk.

My Google home is pretty near 100%; I can count on one hand the number of times it hasn't "heard" me over the past year. That's my benchmark.
