The episodes were set to air earlier this year, on March 28 and April 4 respectively, but were postponed due to the global health scare.
Host Emma Willis will also be fronting an hour-long special re-cap show, looking back at the best moments so far.
Speaking on the current status of The Voice’s return Brooke told Metro.co.uk: ‘Meghan wrote to me on my birthday, she has been really busy with work, I wrote to her but I am waiting on her to let me know.
‘I don’t know how the situation is going to be with her flying back from America but I think TV is now considered as an essential service so she will get a priority flight type of thing, but I don’t know what is going to happen, I am trying to remain optimistic.’
Brooke went on to add that she is also unsure whether her family will be able to fly from Ireland to support her for the live shows.
She continued: ‘Everyone is so cautious but the one thing I want to focus on is keeping my granny safe and for her to travel would be a bit of an ask.
‘It’s not really my decision to make, it will be a decision as a family as to whether they travel or not.’
Despite the semi-final being put on hold, Brooke said she is trying to remain optimistic for the next round.
‘I have thought about what songs I want to do, and I have a clear one in my mind because of the artists that I look up to and aspire to me,’ she added.
‘What I want from the next round, is that I have done a lot of standing still performances that are dramatic or a ballad but now I really want to give a performance and utilise my time.’
Metro.co.uk has reached out to ITV for comment.
The Voice live shows are due to air later this year.
