All these companies keep pushing voice input as
the way to interact with their personal assistants, I personally feel that it would be 100x better to let me interact with them however I choose. In my experience, voice recognition is just not there yet, especially noisy environments, even if some companies are better at it than others.
If I could just type something into Siri I would use it countless times more. Most of my frustration comes from it misunderstanding me, often resulting in me pulling out my phone and typing in my question into search engine anyway.
Additionally, I do not want my business spoken aloud.
