I have a soft spoken, cartoonish, Pinnochio type voice, and Siri, Alexa, OK Google, none of that crap works for me, and she always says, "Sorry, I didn't get that." "I'm sorry, I'm having trouble hearing you." etc. lol. So I'm like damn it, screw this. Stop being lazy, and do it myself.
So maybe with people with more concise and more conventional voices it works for them, but not for me. So yeah lol.
