Build your own voice example for indic languages (Hindi TTS)

[prajwaljpj]

I am new to merlin. I have been trying to build a Hindi TTS system using my own data but end up failing at festival (Segmentation fault).
I am currently using the latest versions of festival, speech_tools, festvox cloned from github. I also tried compiling all the tools with gcc-5 and gcc-7. Here is where it fails.

When I run Step 2 ./02_prepare_labels.sh
