class espnet2.fileio.omniio_audio.OmniIOSegmentsReader(fname: Path | str, wav_scp: Path | str | None = None, always_2d: bool = False, max_cache_fd: int = 32)

Bases: Mapping

Reader of a Kaldi segments file over a wav.scp of Omni-IO entries.

Examples

segments (wav.scp is read from the same directory): : win1 rec1 0.0 10.0 win2 rec1 10.0 20.0

>>> reader = OmniIOSegmentsReader('dump/raw/train_win/segments')
>>> rate, array = reader['win2']

Each segment is cut as SegmentsExtractor cuts it when dumping, but at load time and reading only the segment’s part of the archive entry.

• Parameters:
  • fname – The segments file.
  • wav_scp – The recordings’ scp; default: wav.scp next to fname.
  • always_2d – Keep the channel axis even for single-channel audio.
  • max_cache_fd – Bin files kept open; 0 opens and closes per read.

Read the segments and the recordings’ scp.
