description The method involves determining a value of a mean fundamental frequency for information segment e.g. speech segment. A sub-set of synthesis units whose mean fundamental frequency values are closer to the fundamental frequency value, is selected. Multiple proximity criteria are applied to the selected synthesis units for determining a synthesis unit representative of the information segment. The proximity criteria includes the fundamental frequency or pitch, spectral distortion, and/or energy profile. An independent claim is also included for the utilization of a synthesis unit selecting method for the selection and/or coding of the synthesis units for a very low bandwidth voice coder.
