I&#x27;m not sure what this really does. I mean it&#x27;s interesting but as far I can tell it&#x27;s just searching transcripts or caption data for the word and then queueing that part of the video. There&#x27;s no checking if the word is actually pronounced correctly so you&#x27;re not actually improving your pronunciation.<p>Several videos were not just the wrong pronunciation, the captions were wrong so the person never said the word the system thought was the requested word.<p>A good example is &quot;candidate&quot; which many people pronounce wrongly as &quot;cannidate&quot; Checking the results, first one said &quot;cannidate&quot;, second one said something that sounded like &quot;kennedy&quot;, 3rd one captions were wrong, 4th one was &quot;cannidate&quot; as well.
