For example voice search for &amp;quot;Who was the first president of the United States?&amp;quot; then after you get the result do another voice search for &amp;quot;Who was his vice president?&amp;quot; and Google will infer you are still talking about George Washington.&lt;p&gt;One step closer to conversational interfaces!</text></comment>

These were distorted by noise to get 20 variations (so the training set was 60 million utterances total).&lt;p&gt;I don&amp;#x27;t understand if these were labeled somehow There&amp;#x27;s a section on clustering into 9287 phones, but it isn&amp;#x27;t clear to me if these were used as labels.</text></comment>
