Abstract : Mistral is an open source software for biometrics ap- plications. This software, based on the well-known UBM/GMM approach, also includes the latest deve- lopments in speaker recognition such as latent factor analysis and unsupervised adaptation, or SVM super- vectors. The software performance is demonstrated within the framework of the NIST evaluation cam- paigns. Several applications, like speaker diarization, embedded speaker recognition, language recognition, and pathological voice assessment are also presented.
