According to a Q&A hosted on the game's Steam page, every character in the game is voiced by audio designer Martin Halldin, including Curly, Daisuke, Polle, and "anything that isn't an advert in the tv sections". In the case of Polle's voice, the intention was to have it feel like they were pulling voice clips from random advertisements to string a sentence together. To that end, the words were all recorded individually and cut into sentences during post-production.
