Baseline System for Automatic Speech Recognition with French GlobalPhone Database

This report presents one month trainee work on development of French Automatic Speech Recognition ASR system using a french part of multilingual database GlobalPhone_FR. The purpose of this report is to explain and give results of the training and testing of the ASR with this specific database. Two different methods are presented, the Hidden Markov Model (HMM) with MFCC/PLP features and tandem features from Multilayer Perceptron (MLP) phone posteriors. The report presents data preparation for GlobalPhone_FR ASR training, and compares the two different approaches. Word recognition accuracy achieved with MFCC features is 71.46% and the tandem features with 3-layer MLP improved the accuracy to 72.15%. We interpret this result as a baseline for the GlobalPhone_FR database.
