Actually, in this case, the French would not liaise "chat" and "est".
when you listen to the liaison it could also mean "chatte est" instead of "chat est".
thank you. so why is there a liaison in the example?
because the voice you hear is not always accurate (many mistakes of this kind)
I am having such a hard time understanding the pronunciation, both regular and slow.
The app didn't accept its own voice as a correct answer...
