Re: [Kaldi-developers] GMM based model statistics

[Arif K. <ife...@gm...>]

Thank you very much Daniel for such a detail answer.

One more question in this regard,

Do we have a maximum limit specially for No. of leafes, if we add more
corpus for training like WSJ than TIDIGITS or WSJ than Air traffic data.

Best regards,
Arif
