KeyError: 'mgc'

[Norbert G]

Hello,

I am trying to synthesise my held-out data using duration model, so changed in config file DNNGEN and GENWAV to True, run the script and got the following error msg:

KeyError: ‘mgc’
I checked in the gen folder I have a cmp for every file so assume DNNGEN went ok. Why is mgc as key error? is it the type of variable what is wrong? I belive mgc are a must to GENWAV, so I am wondering what’s wrong? Could somewone explain, please?

Sorry, I checked it again and I see that DNNGEN only creates cmps and next produces this error. Maybe it is supposed to create all necessary acoustic features bap, f0 and mfcc as well? where do I specify what the output should be? Is it in a duration config file by any chance?
In addition, the file parameter_generation.py has (at least in my version – Merlin for Ossian) in the main() function following paths:
in_file_list = [‘/afs/inf.ed.ac.uk/group/project/dnn_tts/mtl_dnn/gen/dnn_2500_601_229/hvd_678.cmp’]
and a variable var_file_dict a dictionary which values are some other paths.
I believe they should be updated? If yes, could someone explain what is their function?
Anyone assist, please?
thanks,
Norbert
