Allophones in automatic speech recognition

The common approach to speech recognition problem is the use of phonemes as basic parts of speech. The authors proposed allophones usage instead. For rarer allophones the conversion into other allophones (4 selection methods) has been proposed. Based on the obtained results one can say that the effective use of the additional information from the allophonic notation will not be possible without modification of currently used algorithms.
