Salut MichaelH133 et RobertR34 !
MichaelH133, the "ee" sound of y can indeed sound short when people are speaking quickly - native speakers tend not to lean on it or emphasize it.
If you're having trouble picking that sound out of the phrases, it's likely just because your ears aren't used to hearing these sounds and are having trouble picking them up! That is a common problem for learners of a new language. I have a couple of suggestions that might help.
1. Be Sure to Wear Headphones
It may be helpful to wear headphones when you're listening to the audio - this can help to isolate the sound and allow you to hear all of the aspects of a phrase better. Increasing the volume a little and closing your eyes as you listen can also help you focus on what you're hearing.
2. Practice Sound Breakdowns
Something else you might try is to say the phrases you're having trouble with very slowly out loud, pronouncing each word individually as you go through it (e.g. "il," "ee," "ah" for il y a). Using the Rocket Record playback feature can be helpful with this, because then you can play what you've said back to yourself as well and listen carefully to each individual sound. Once you're familiar with each separate sound, begin to say the phrase a little more quickly. As you speed up, you'll notice how the sounds you're making naturally begin to shorten and blend together. Then, when you're ready, try listening to the native speaker audio again and see if you can pick up that y sound.
It can take some trial and error to make your ears get used to French sounds, but as you get more and more exposure to the language, you'll actually start to hear more and more things that you weren't even aware were being said!
I hope that that is helpful for you! Let me know if there's anything else I can do.
Bon courage !
