""" Res2Net implementation is adapted from https://github.com/wenet-e2e/wespeaker.
|
||||
ERes2Net incorporates both local and global feature fusion techniques to improve the performance.
|
||||
The local feature fusion (LFF) fuses the features within one single residual block to extract the local signal.
|
||||
The global feature fusion (GFF) takes acoustic features of different scales as input to aggregate global signal.
|
||||
ERes2Net-huge is an upgraded version of ERes2Net that uses a larger number of parameters to achieve better
|
||||
recognition performance. Parameters expansion, baseWidth, and scale can be modified to obtain optimal performance.
