Hi there, I'm a portuguese sound designer who knows Bingo very well. I've played it a few times as it is very common here in our country. I've been designing audio for games, short-films, animations, etc. which has brought me a lot of experience in editing voice and also creating sfx. I assume my voice would be a good fit, I can send you a demo of it. In case you don't like it, I can also reach out to someone else with a better sounding voice, without charging any extra costs. Feel free to check my portfolio!
Best regards,
Francisco
