An arrangement is provided for compressing speech data. Speech data is compressed based on a phoneme stream, detected from the speech data, and a delta stream, determined based on the difference between the speech data and a speech signal stream, generated using the phoneme stream with respect to a voice font. The compressed speech data is decompressed into a decompressed phoneme stream and a decompressed delta stream from which the speech data is recovered.
