Introduction
This recipe trains multi-domain ASR models for AliMeeting. By multi-domain, we mean that we train a single model on close-talk and far-field conditions. This recipe optionally uses [GSS]-based enhancement for far-field array microphone. We pool data in the following 4 ways and train a single model on the pooled data:
(i) individual headset microphone (IHM) (ii) IHM with simulated reverb (iii) Single distant microphone (SDM) (iv) GSS-enhanced array microphones
This is different from alimeeting/ASR since that recipe trains a model only on the
far-field audio. Additionally, we use text normalization here similar to the original
M2MeT challenge, so the results should be more comparable to those from Table 4 of
the paper.
The following additional packages need to be installed to run this recipe:
pip install jiebapip install paddlepaddlepip install git+https://github.com/desh2608/gss.git
./RESULTS.md contains the latest results.
