Whether Bob has the relatively complete implementation example of i-vectors + LDA/WCCN/NAP?

[Jinfang Wang]

Hi every one,

I have the desire to extract i-vectors by GMM-UBM using Bob as a comparative approach.  

I aslo have to implement intersession compensation using Linear Discriminant Analysis (LDA), Within-Class Covariance Normalization (WCCN) and Nuisance Attribute Projection (NAP) which were proposed in the paper, "Front-End Factor Analysis for Speaker Verification". Could you tell me whether Bob has the relatively complete implementation example of verification or recognition?

Thank you for your warmhearted help.

Hi,

We do have these implemented in Bob. I am not sure about NAP though.

Please look at
bob.learn.em
bob.bio.gmm
bob.bio.spear
bob.bio.base

Best,

Amir
