The 29-year-old musician wowed coaches Blake Shelton, Christina Aguilera and Cee Lo Green on Monday night (February 13) with her blind audition performance of 'Maybe I'm Amazed'.
She opted to join Team Blake.
Speaking to reporters on a conference call, she said: "When I hit that stage I just wanted to do what was in my heart, and it came off really well, I think. I chose Blake because he said everything I needed to hear and turned around before I did anything I thought might get people to turn around.
"He heard something genuine in the soft part of my voice and I really like that about him. I think the base of what I am doing is my intention of going back to the roots of where I came from and why I love music in the first place."
She added: "I think working with Blake could bring out something that maybe would never even have occurred to me, so in the moment it was an easy choice."

During the call, Unga also joked about challenging fourth coach Adam Levine on why he didn't press his button, saying: "When I watched it I was like, 'I cant believe I said that to him! How rude! What was I thinking?'"
However, she went on to explain that before taking to the stage host Carson Daly had told her that 'Maybe I'm Amazed' is one of the Maroon 5 frontman's favourite songs.
"I was genuinely curious about what I had missed for him," she said. "If it is one of his favourite songs it makes sense to me he'd hold it close to his heart and look carefully to what I was doing and be critical of that."
Unga previously appeared on the CBS reality series Rock Star: INXS and told reporters that she is thankful for all the opportunities she has received in the industry.
"It's been such a journey for me to keep doing music for a living," she said. "Not a lot of people get as many chances as I've gotten and to be in this position again, I'm so thankful and overwhelmed and it means a lot to me to be here."
She added: "I think it means a lot to the people who have followed me throughout the years through all my successes and all my failures.
"I'm holding on tight to this one and taking it as far as I can for sure. It feels really, really, really, really good to be here."
As for the future, she said her main focus right now is returning to "why [she] started doing music in the first place" and performing songs that listeners can relate to.
"That's always been my gift as a musician, to really pull at people's heart strings. That's what I enjoy about doing what I do - the emotion and everything about that."
