If the noun starts with a vowel or a mute H, always use "ton," no matter the gender. It gets rid of the double vowel sound in "ta" and "eau," making it sound smoother.

That's fine as well; it's just not what the audio said. You can use votre when speaking to more than one person or if you want to formally address someone.

I can't give it a listen but the pronunciation is fairly close as long as the o and the nasal on aren't well discriminated - which is definitely tough for non natives

So fair mistake at your level. If you ever have a doubt on something like this, make sure you try a listen in the slow mode, as it usually separates the words quite clearly. It's very likely you would have caught it here.

Happy learning!

I understand it can be difficult at first, but you can use the google translate app to listen, I use it for German and Italian words mostly, my mother language is Dutch and I am suprised how wel the Dutch-words are being pronounced, way better than forvo.com. :)
