    • Interframe differential coding of line spectrum frequencies 

      Erzin, E.; Çetin, A. Enis (IEEE, 1994)
      Line spectrum frequencies (LSF's) uniquely represent the linear predictive coding (LPC) filter of a speech frame. In many vocoders LSF's are used to encode the LPC parameters. In this paper, an inter-frame differential ...
    • Subband analysis for robust speech recognition in the presence of car noise 

      Çetin, A. Enis; Yardımcı, Y.; Erzin, Engin (IEEE, 1995-05)
      In this paper, a new set of speech feature representations for robust speech recognition in the presence of car noise are proposed. These parameters are based on subband analysis of the speech signal. Line Spectral Frequency ...
    • Teager energy based feature parameters for speech recognition in car noise 

      Jabloun, F.; Çetin, A. Enis; Erzin, E. (Institute of Electrical and Electronics Engineers, 1999-10)
      In this letter, a new set of speech feature parameters based on multirate signal processing and the Teager energy operator is introduced. The speech signal is first divided into nonuniform subbands in mel-scale using a ...
