The problem about last phoneme alignment

Hi, thanks for this great job, I have tried to integrate it on the top of my asr module, most of the phonemes were aligned perfect except the last, as can see in the below.

the top figure was the original wavform, and the bottom was the alignment result. I found the wavform approach the end was cut down, and the index_duration was right because the phonemes except the last were aligned accurately.

So how can I solve this problem? thanks in advance.

My TTS model has the same architecture as Fast Speech, except inject a speaker embedding into every timestep input.

And I think this tool is more suitable for me because the montreal forced alignment tool is a little intricate which is based on kaldi and I hope to train all models in tensorflow only without other framework. Now it solved my problem easily.

Thanks again for your timely response!
