* add the `voxpopuli` recipe - this is the data preparation - there is no ASR training and no results * update the PR#1374 (feedback from @csukuangfj) - fixing .py headers and docstrings - removing BUT specific parts of `prepare.sh` - adding assert `num_jobs >= num_workers` to `compute_fbank.py` - narrowing list of languages (let's limit to ASR sets with transcripts for now) - added links to `README.md` - extending `text_from_manifest.py`

Usage example:
|
|
python3 ./local/display_manifest_statistics.py data/fbank/*_cuts*.jsonl.gz
|
|
|
