I speak fluently three languages (english, spanish and portuguese) and I can record good audio productions in any of them. Besides that, my fluency includes lack of accent.
I have a Vedo BM800 condenor plus equipament that improves it perfomance. I use audacity, adobe audition and voicemeeter as software, so the final version of my audios have good quality.
With me we can widen the target public by adding more than one language to the production.
