It's useful, but after so many years the state of machine translations and speech recognition in general is still not exactly reliable. It's like it doesn't have context or doesn't know how to apply it. I've heard success stories like this before, experienced them a few times as well, but most of the times the experience for me is subpar to the point it gets so annoying and needs so much manual intervention I gave up, thinking I'll just try again in 5 or 10 years and see if it's any beter.
Maybe my accent or pronounciation sucks but I tried getting Siri to write down text messages about 10 times. Most of the times it was close, but none of the times the words were 100% correct and in more than 50% of cases that led to the produced sentences not conveying the original meaning. Same for navigation. Names of cities (in Europe) seem problematic, like confusing Miltenberg (DE) with Milton in Canada or so. Similar for Google Translate. Our Portugese taxi driver didn't speak English and was worried about getting us to the airport in time. His phone showed us he was worried about the weather. I get 'tempo' can mean both, but it's these subtle differences technology still is lacking.
My wife's name is Nada. I pronounce it nA-da and siri says nah-da. If I don't use the siri pronunciation it won't find the contact. Took me a while to figure out that work around.
I have a similar problem with my car's native voice recognition. But Siri gets both the recognition and pronunciation correct. I wish my car had CarPlay.
