I know warren buffett and his company.and this inetview is very well for medium level .
Does anyone know why the video did not show where I spoke wrongly? like before, the line, after recording, showed which words were spoken wrongly by a mark "i" and clearly showed where the error came from, ie dropped "r" or added "uw" or stressed wrongly. Now, the problematic words is shading or twinkling twice, and they show how I spoke and how the native did. I don't like this new function and wanna come back to the old one. Thx for your guidance
