NVIDIA Neural Modules 1.5.1

Features

• Minor updates to expose speaker id, pitch, and duration on export of FastPitch #3192, #3207

Known Issues

• Training of speaker models converge very slowly due to a bug (fixed in main: #3354)
• ASR training does not reach adequate WER due to bug in Numba Spec Augment (fixed in main : #3299). For details refer to #3288 (comment) . For a temporary workaround, disable Numba Spec Augment with https://github.com/NVIDIA/NeMo/blob/main/nemo/collections/asr/modules/audio_preprocessing.py#L471 set to False in the config for SpecAugment in the yaml config. The fix will be part of 1.6.0.
