https://techcrunch.com/2018/08/01/snapchat-launches-its-first-speech-recognition-lenses/ > Snapchat is today launching new lenses that respond to voice commands. The company says it’s now rolling out a series of lenses that will animate when users speak simple, English words like “hi,” “love,” “yes,” “no,” and “wow,” as opposed to taking some other action – like opening their mouth or raising their eyebrows, as has been the trigger for some of the company’s prior lenses that animate with special effects. > For example, saying “hi” in the new lens will launch an animation that surrounds you with a flock of chatty birds; “love” will play cheesy jazz music; “yes” creates a zoom effect; “no” puts you in an infinite photo tunnel; and “wow” puts a bow on your head and surrounds you with the word.
