Bibliography latex in french

Question

I am using \bibliographystyle{plainnatfr} to generate references. For example,

@inproceedings{cohen2003inference,
  title={Inference of human postures by classification of 3D human body shape},
  author={Cohen, Isaac and Li, Hongxia},
  booktitle={Analysis and Modeling of Faces and Gestures, 2003. AMFG 2003. IEEE International Workshop on},
  pages={74--81},
  year={2003},
  organization={IEEE}
}

when I use citep{cohen2003inference}, it generates Cohen and Li. How can i get the french version Cohen et Li ?

Answer 1

With this package \usepackage[french,english]{babel} and before the \printbibliography you can use \selectlanguage{french} to obtain it.

EDIT

As indicated in comments, it is before the \bibliography{file} instead of \printbibliography
