Hi Venkata,

Have a look at Google Cloud's Wavenet which has a Vietnamese option plus very realistic voices.  You'll need a Google Cloud account and need  to use credit card but there is a very generous free allowance and extra time is cheap.  You'll also need a wrapper/software to make it easy to use (https://github.com/pgmichael). The app converts html text into a range of voices, including Vietnamese (https://cloud.google.com/text-to-speech/docs/voices). To get my text into html I used a free Wordpress account.  Once set up can convert and download text to MP3 speech in about 10-15 seconds.

Hope this helps.
