描述

In the large data recipes in Kaldi many single job scripts in steps/* and utils/*, which were very fast for normal sized LVCSR tasks, consume several hours. e.g. on fisher_swbd/aspire the utils/data/get_utt2dur.sh script runs for a few hours.

We need to update these scripts to add parallelization support.

Required skill: shell scripting

研究方向: First, examine existing single job scripts like utils/data/get utt2dur.sh and steps/compute cmvn stats.sh to understand their current structure. Then, look at how Kaldi already implements parallel jobs in other scripts (e.g., using utils/run.pl or utils/parallel.pl). The goal is to modify these scripts to split work across multiple jobs while maintaining correctness. Finally, test with large datasets to verify performance improvement and ensure no regression. Since the issue is from 2016, check if any partial work exists in the repository or related forks.
