I thought it was a meme dub at first, but there are multiple videos with the same sounds.. 
Here is a slightly longer video of the French Starmie sounds. 
Not the sound you’d expect when tackling a Golduck, lmao.
I lol-ed when I read this comment somewhere:
The French Goldeen isn’t much better (love how aggressive Misty sounds in French at the start of this video lol):
