It was during the filming of the show that if she needs to speak to someone at the opposite end of the room, she needs to speak in a loud voice in order to project herself. Another thing she picked up from working on Akibaranger is the user of her entire physical self to act and bring out the character in the show.
Also in the same interview, she revealed that she wants to graduate from playing chuunibyou (eighth grade syndrome) characters. She also talked about her career and what roles she want to play in the future. You can read the entire interview on xDantheManx Online.
