Whilst I want Siri to be better, I mostly don’t care.
Yes, The simple solution is to learn to speak Siri's language. Siri will never learn real English.
For example I can say "Hey Siri set kitchen lights to 85%" and the dimmer is adjusted to the desired brightness. If I change any of those words there is a chance of error. So I learn to say the phrases exactly as Siri wants. Same with sending texts and setting destination for maps app. You need to use the exactly "corect" words and speak each word clearly.
Yes i could be better but it is not so hard to learn "Siri Speak". Well it is not hard, perhaps because I've been a software developer for five decades, and I've gotten used to using the computer's language.
We have come so far. I first stared studying speech recognition and AI in the mid 1980s as a graduate student and that you could do it at all was exciting.But now people complain that Siri has less than human ability.
What if Apple used GPT-like systems? You could ask, "Please tell me about George Washington's first grandchild Susan." and you'd get a nice biographical summary, even though GW had children or grandchildren. It is also fun to ask about Beethoven's 10th symphony. Generative models are VERY good at generating text. But they have basically a negative IQ. They are worse than stupid. Even worse. If you publish this made-up stuff then it gets used in the next set of training data for the next version of GPT. So we get authorize answers about made-up facts.
Apple and Google have a really hard problem on their hands. These systems are good with language but are far less intelligent than my dog. The only solution is FAR beyond the current state of the art, These systems must be able to understand what they are saying. We are not even close to that yet, No one has a clue how to do that.
So, what we have is useful already, and be careful what you ask for.
