Foreign accent conversion through voice morphing Conference Paper uri icon

abstract

  • We present a voice morphing strategy that can be used to generate a continuum of accent transformations between a foreign speaker and a native speaker. The approach performs a cepstral decomposition of speech into spectral slope and spectral detail. Accent conversions are then generated by combining the spectral slope of the foreign speaker with a morph of the spectral detail of the native speaker. Spectral morphing is achieved by representing the spectral detail through pulse density modulation and averaging pulses in a pair-wise fashion. The technique is validated on parallel recordings from two ARCTIC speakers using both objective and subjective measures of acoustic quality, speaker identity and foreign accent. Copyright 2013 ISCA.
