I was watching some anime today, and I heard "y" sounds in places I didn't expect.
Here's a sound clip (MP3) and my transcription:
There are two "y" sounds I didn't expect. I'm not sure whether they're related.
世界へsounds like "sekai ye" rather than "sekai e".
世界をsounds like "sekai yo" rather than "sekai (w)o".
Can anyone explain these "y" sounds to me? Are they standard? Common?
