Synthesise

We can now put unseen sentences through the system, to perform synthesis.

Edit your config file to turn synthesis on

NORMLAB  : False
MAKECMP  : False
NORMCMP  : False
TRAINDNN : False
DNNGEN   : True
GENWAV   : True
CALMCD   : False

and run this step

$ python /Volumes/Network/courses/ss/dnn/dnn_tts/run_dnn.py feed_forward_dnn_WORLD.conf

You will now have synthesised waveforms in gen for your validation and test files.

At this point, we have a system that can only synthesise held-out sentences. This is because we are using the durations from forced alignment. To make this a fully-functional TTS system, we will need to add a duration model (but that is left for another day).
