Your voice sounds fine to me and I understand every word, yes, you have an accent, but everyone does - so what?
The truth:
Some people will love your voice, some people won't care and just be interested in what you have to say, some people won't like your voice.
I doubt it will happen, but if anyone gives you a hard time about it, the problem is theirs and you should just ignore them - simple!
Be free - spread your wings and fly :)
Thank for making the video, it's something I have done a long time ago, but nice to see this idea again!
