Yea - I don't think voice commands are a feature particularly desired for speakers. There are only a few instances I can think of where I want my speaker to respond to voice commands - when I'm in the shower and when I want it to be silent so I can take a call being the primary ones. For the former I think just having a playlist on shuffle is good enough and the for the latter there are better solutions available by integrating my phone into the system.
Using voice commands to control music has always seemed like a sisyphean task to me. You're using a control method that directly conflicts with the state you'll generally use it in and song/artist names are so dense and confused that oftentimes you'll need multiple commands to hone in on what you actually want.
My "smart speaker" (aka desktop computer with massive speakers) is simply controlled by spotify sync which is absolutely not amazing but it's also not not terrible and far easier to control than times I've tried shouting at voice devices in the past.
The mic in these home devices is, imo, 90% for cooking and 7%[1] for other alarms and timers - they're relatively poor music platforms and only moved into the space because of how subsidized they were by Amazon and other companies.
1. (edit) bumped down from 9% to 7% because smart lights and thermostats are also quite prevalent.
