Am I the only one that finds text to speech cumbersome and more of an impediment than anything else? I applaud the effort, but spreadsheets are difficult enough to navigate at the best of times, let alone trying to manipulate with your voice.
Running precise commands? Keyboard wins.
No keyboard? I love the voice search of my roku 4 over trying to search via virtual keyboard and arrow keys, or using my Amazon Echo to find artists/songs
Long text? While I prefer typing, I remember one author I heard (Kevin Anderson, I think) who dictates all his books (first drafts) into a mini-recorder and pays someone to transcribe them. I find that hard to comprehend, but I bet he's not unique.
Spreadsheets? Keyboard wins for data entry, but I bet voice would be convenient for analysis. "Sum column B" "What is the average of column D, excluding 0 values"
