Ariana Grande reveals why she changes her voice so frequently

Ariana Grande has insisted she changes her speaking voice to "preserve" her vocal health.

The 'Wicked' actress has addressed her changing timbre, with some fans still criticising her for speaking in a higher register than she did in the past.

She told the 'Smartless' podcast: "The thing that I do that perplexes people so much — and it's just so funny because if you're a person who uses their voice, you know about this.

"If I have a long day of press or if I have to sing, I'll place [my voice] a little higher. I'll change my vocal placement to kind of preserve.

"But that is just something that's healthy for the voice. It's just basically pitching your voice up a tiny bit.”

The 31-year-old star called out her haters, insisting the criticism of her voice is "interesting".

She argued: "It's just a normal thing for vocalists. But people are like, ‘That's not her natural voice.’

"And I'm like, ‘Well, it is actually, but it's just a little higher. All of it is natural.’”

Ariana faced a lot of criticism over her voice as Glinda the Good Witch in 'Wicked', and she acknowledged it won't end any time soon.

She quipped: "It's so funny because I’ve talked about it a zillion times, and people are still like, ‘Where's your real voice?’ And I'm like, ‘Well, they all are.’”
