An i-vector system consists of a trainable front end that learns how to extract i-vectors based on unlabeled data, and a trainable backend that learns how to classify i-vectors based on labeled data. Other MathWorks country sites are not optimized for visits from your location. In general, reducing the data set is a good practice for development and debugging. LibriSpeech is a processed subset of LibriVox. I am trying to write matlab code for unsupervised speaker diarization system for my thesis.
