Originální abstrakt

Many current systems for automatic speech processing rely on sub-word units defined using phonetic knowledge. Our paper presents an alternative to this approach -- determination of speech units using {ALISP} (Automatic Language Independent Speech Processing) techniques. Such units were experimentally tested in a very low bit rate phonetic vocoder, where mean bit rates of hundreds bps for unit encoding were achieved. Improvements of the proposed coder and some links to ``classical'' approaches of speech synthesis are discussed. Based on the results of comparison of an ALISP segmentation with a phonetic alignment, we comment on the potential use of automatically derived units in speech recognition, speaker verification and language identification.
