This paper first introduced i-vectors. You should also read about Joint Factor Analysis since it's related. The i-vector system in Kaldi uses a TDNN-based UBM, details of which can be found in this paper. 

To look at speaker verification using i-vectors in Kaldi, check out the v1 directories of recipes like VoxCeleb, SRE16, etc. i-vectors are also used in the ASR recipes since they provide some improvement in WER. As an example, you can look at the chain model in mini_librispeech here.

I beg your pardon. Only the egs/sre10/v2 recipe uses the TDNN UBM. The other ivectors recipes are pretty similar to the first paper I linked.
