One of my disappointments with Siri is its dependence on looking at and touching the screen. If I say to Siri “I need directions to Walmart”, it will show a list of Walmarts and demand that I look at the list and touch the one I want. Siri could be programmed to ask (maybe in a hands free mode) – “I found 5 Walmarts near you – would you like me to read the list to you?” And then a Yes/No voice response to select which one. Many times Siri will ask a yes / No question but not allow a voice response.
When I was driving across Pennsylvania from CT to Chicago, I tried to use Siri for sending texts to my cousin without looking at the screen. It was infuriating. No matter how many times it misunderstood the name of my cousin, it didn’t learn after 10 times of me answering “no” to “Do you want to sent this text to Taco Bell?”. Siri also invariably thinks my questions are related to the menus of nearby restaurants and announces things like “there is no restaurant nearby that has Google Kit Kat”. Since this is all done in server side software, I figured Siri would become better after 5 years. If anything, it is worse, and Siri can’t even sing a song. I switched Siri to use a male voice.
