Are Zelda games getting more voice acting?

So when I first played Triforce Heroes, I noticed characters seem to grunt more frequently than they do. Quite a bit. There's also Madame Couture who makes an unusually vocal sound. It makes me think that future games will feature more vocal characters that aren't Link. I'm unsure about full voice acting but maybe that's possible.

There has been characters with fully voiced words in the past like Beedle's "Thank You!" but Triforce Heroes makes me think they may go further in future games. Or is it just because it is a spin-off?

Voice acting never has really been a big part of Zelda, so I don't expect it to be anytime soon. There's always been characters that make noises like that, or even sound like they're saying full phrases like Midna in Twilight Princess. It's not really anything new.

Well in some game like Minish Cap, when your being lead around by Zelda she says, "Hey" & "Hello." But usually it's not much that characters say, which is nice. I always found Beatle says; "Hai." to me a bit creepy. XD

I think they will save the voice acting for movies. The grunts work better for most games since I would not want a fairy talking for Link,
