The present invention relates to a method and arrangement for transforming phonemes over a shorter or longer time than an existing phoneme. The transformation takes place asymmetrically in that a basic phoneme is divided into a number of points, the said points being identified with respect to information-carrying elements in the phoneme. This provides a weighting in the phoneme between information-carrying elements and elements carrying less information. The parts of the phoneme which elements carrying less information are transformed over a longer or, respectively, shorter time interval. Elements in the phoneme which represent information-carrying parts are transferred unchanged in time. This provides a transformation of the phoneme which retains its original character in all essentials. By the parts of the phoneme carrying less information being identified, the invention also provides an indication of where different phonemes can be fitted into one another in the creation of artificial speech. |
