Unfortunately “Hey Siri” starts to grate the 70th time you say it in 3 days. I would actually now rather walk across the room to touch the Homepod than have to say the phrase so much. It’s still in uncanny valley territory a lot of the time as it isn’t smart enough to keep context between interactions or react in a human-like way.
I think a retroactive activation feature would be the way to go, ie. be able to say “Siri” at the end of a sentence and have it parse the phrase that came before. It feels more natural to say “skip this please Siri” than “Hey Siri, skip” because it lets you amend the mistake of not identifying the subject earlier in the sentence rather than the phrase-exasperation-hey Siri-phrase.
I asked Siri to DJ and my daughter said “hey Siri, I don’t like that song”. Siri said “I’ll remember that” and played something else. Now I have no idea how to amend Siri’s notion that I dislike one of my favourite tracks. There should really be a Homepod app where you can see recent interactions and correct misinterpreted ones.
There are also some artists and tracks with unusual spellings that are always going to cause problems for a voice interface and so they need a solution for that.
