Hello, I'm an author in Vietnam. My readers often tell me that I have a talent voice, so I just try this job. I can do voice over in Vietnamese for you. You can listen to the demo by the links below (just copy the link to your browser)
Relaxing voice: https://youtu.be/R1GHptRHrnE Audiobook voice: https://youtu.be/cf-Bb6WZDNE (the Vietnamese voice is mine)
Note: I do this just for help (not for money). I'm confident about my writing skills (in Vietnamese) so I will make sure that your transcript will be polished so well (if you need that).
