Is there any way to get timestamp,not only the start time of word,but also duration

For CTC, yes, it is possible to get the start time and end time of a token (You have to infer the start and end time for a word from the corresponding tokens).

For transducer-based models, we can only get the start time, not the end time (so it is not possible to get the duration).

We have already some recipes that supports getting timestamps (only the start time of word currently). E.g.,

  • For conformer-ctc model, please refer to https://github.com/k2-fsa/icefall/blob/master/egs/librispeech/ASR/conformer_ctc3/decode.py.
  • For conformer-transducer model, please refer to https://github.com/k2-fsa/icefall/blob/master/egs/librispeech/ASR/pruned_transducer_stateless4/decode.py
