Is there any way to speed the alignment process?

Thanks for supporting such an excellent tool to align sentence and audio!

I have a question that is there is a way to speed the alignment process? Now i have about 80k pairs of audio files and transcripts to process.... There is a RTX2080 on my server, while use this command `bin/align.sh --catalog demo.catalog` only use about 153Mb of the total 11Gb memory.
