Some neural voices erroring out on some text but the same neural voices works on other text files.

Hi there,

I am trying couple of text files (converted to text from pdf using google vision) to convert into audio form.

However some neural voices work and some gives internal error 13.

Also, the neural voices erroring out on this particular one works on other text files.

Is there a way to know what is the problem in file if there is any.

Text didn't get converted to audio when used with en-US-Neural2-J.

Same text converted with en-US-News-K.

I can attach the files if you would like to look at them to get to root cause.

Can you please advise?

 Thanks for your help.
