  • Abstract
    A method for modifying formant locations and bandwidths directly in the line spectrum domain is developed. This method is based on first-order approximations between different representations of the linear prediction spectrum and does not require finding the roots of the prediction polynomial. In addition, this method is less sensitive to pole interaction problems associated with direct pole modification.
