Listen to me, I am French :) So, know that the voice of Duolingo and the voice of Google Translate are very bad for French Actually, we do a liaison between "est" and "énorme", so we say "Ton cochon est ténorme" But if you don't do the liaison, French people will understand you as well ! I hope i helped you :)
Google uses the liasion - https://translate.google.co.uk/translate_tts?tl=fr&q=%22Ton%20cochon%20est%20%C3%A9norme%22
Duolingo frequently misses this. "Est" will liaise, while "et" does not (source, French Today)
These are all possessive adjectives: "Ton" and "ta" are the familiar form (used whenever you would use "tu" for "you). "Ton" is used for masculine gender nouns and "ta" is used for feminine gender nouns. If you have a feminine gender noun that begins with a vowel, you need to use "ton" (not "ta"). "Votre" means "your" and would be used with either masculine or feminine gender nouns; it is used whenever you are using "vous" for "you".
