  In multilingual speech recognition systems, a situation can often arise when
the language is not known in advance, but the signal has already been received
and is being processed. For such cases, some generalized model is needed that
will be able to respond to phonetic differences and, depending on them,
correctly recog-nize speech in the desired language. To build such a model, it
is necessary to set the values of phonetic parameters, and then compare similar
sounds, establishing significant differences.
