title: Fastest Speech recognition library C++
body: <p>I know its a general question topic, but still i want to know whats the fastest speech recognition library in C++?</p>
  
  <p>Currently I am using Microsoft SAPI with kniect. It works fine and recognizes words but its abit slow, some times it takes 1,2 seconds to recognize a word and in my case this lag is causing alot of interaction issues for the user.</p>
  
  <p>I checked the sample provided with the kinect, in which the turtle moves left right according to words recognized but even thats a bit slow. </p>
  
  <p>So I was wondering if there is any faster library then sapi, that can be used in cases like a robot using voice recognition you say "left" then "right" but robot keeps moving left and turns right after 1,2 seconds its a bit frustrating for the user.</p>
