To a degree, yes. Like any other tool it has limitations.
When Siri came out, i suddenly realized how much i really did not want to 'converse' with computers. I want them to take commands quickly and the first time and thats about it. I literally had Siri the day it came out (Iphone 4s). After a few years of trying her and google's voice command, i found most of the time i prefer other input methods.
I have voice search on my Google TV Nexus Player ,which i actually use, it voice indexes my Plex Library, down to the episode. I say 'Encounter at Farpoint' (Star Trek TNG Pilot Episode) and BAM I have Q in my face. However, if i say 'Joust like a Woman' (King of the Hill, Season 6, ep. 8), it looks for 'just like a woman' no matter how i pronounce it. Its that inconsistency and inability to make it understand me that will always keep voice search as a niche input method.
