The updated article says that the phrase being triggered is "Alexa, laugh". As long as it somehow mishears Alexa, 'laugh' is a very short phrase that seems easy to accidentally detect (maybe even by a cough). That's probably why this one was occurring more frequently than other possible triggers, and would also explain Amazon's fix of changing the trigger phrase to "Alexa, can you laugh?".
