Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
It may perhaps be that the Thai voice has to be female - if they did not record (or transcribe digitally, etc.) a male speaking the Thai language.
But try going into
Language & input
and tap on the Settings icon next to
"Google text-to-speech engine"
then, under installing voice data, select male voice instead of female voice.
If there is not Google Voice male Thai voice available, then you may possibly be able to find another translator that will translate to Thai in a male voice... let me know if that is what you need help with, and I will search for such an alternative.
If this answers your question, please rate my answer. - A five-star rating would be appreciated!
