I use a Samsung Galaxy E7 mobile phone with the latest Google Chrome web browser installed. My android operating system version also up to date. Since yesterday, I experienced that the 'listen' button (marked on the snap-shot) has gone from Google dictionary results. Here is a snapshot showing the missing icon which I captured from another mobile phone today.
Please suggest me a solution to get it back. It is really important to me as a student who learns English as the second language.
