It takes a true # fan to have fun with poor speech recognition. I gave Siri a couple of tries on iPhone and stopped using it completely, it's totally useless for me.
Well it actually takes a quirky sense of humor, I suppose.
Oh most of the time Siri is very accurate for me. More so on the Apple watch than on the iPhone, as a matter of fact. I have a very clear voice and excellent diction. I have a slight southern drawl as a result of growing up around some transplants from deeper southern states, but growing up in the Mid-Atlantic region I am aware of it and tone it down when speaking to Siri.
But aunts vs. ants tripped Siri up. That's actually the third version of the text. I deleted two previous attempts. So by then I was frustrated and mumbling at Siri so Siri got other words wrong.
The Calzones text was sent while I was standing in the garden, quite a mess. I could not touch my phone with dirty hands but could use my watch to text. It rinses clean, after all. There was quite a lot of ambient noise at that time so it did decently well under the circumstances. I sent other texts from the garden that turned out fine. It is still so much better than autocorrect is for me. I hate texting from my phone and will rely on Siri from now on.
My husband has a lower pitched voice and does not enunciate or speak very clearly because he has the atrocious habit of mumbling. So he has had some problems at first. I do think Siri is being a bit of a speech therapist and breaking him of some bad habits, because I notice he mumbles to me less! He's dictated many texts to me successfully recently.
I'm not implying YOU mumble. The watches aren't working uniformly well for everyone across all of the features. From taptic feedback to speaker quality to accuracy of Siri, there's been some variance.
