# Long description

This is a screenshot from Interactive 1, showing the wave pattern for the spoken word ‘yes’ followed by ‘no’. ‘Yes’, on the left, has a group of spikes that look like a ball, followed by a ‘tail’ of small, bunched-together lines (probably the high-frequency hiss at the end of ‘yes’). On the right, the vertical lines for ‘no’ make a ball with no tail. Their amplitude is greater, possibly because ‘no’ is more emphatic than ‘yes’ and we say it louder.
