Time-Frequency Principal Component (TFPC) is a speech parameterization technique based on a principal component analysis applied to acoustic feature parameters augmented by their time context. In this paper, we investigate on the performance of TFPC in the framework of automatic language recognition. In our experiments, identification rate is improved compared to the use of the conventional cepstral coefficients augmented by their Δ coefficients.
