STABILITY OF FISH MUSCLE PARVALBUMINS AT DIFFERENT pH VALUES

Parvalbumins of herring (Clupea harengus) and carp (Cyprinus carpio) are essential components of the pattern ofsarcoplasmic proteins used for fish species identification by isolelectric focusing. In fishery products oflowpH, like marinated herring (pH ～ 4), parvalbumins were not detectable. It was demonstrated for herring and carp that parvalbumins were not precipitated at pH 4, but were degraded by fish muscle proteases.     

Error analysis to improve the speech recognition accuracy on Telugu language

Speech is one of the most important communication channels among the people. Speech Recognition occupies a prominent place in communication between the humans and machine. Several factors affect the accuracy of the speech recognition system. Much effort was involved to increase the accuracy of the speech recognition system, still erroneous output is generating in current speech recognition systems. Telugu language is one of the most widely spoken south Indian languages. In the proposed Telugu speech recognition system, errors obtained from decoder are analysed to improve the performance of the speech recognition system. Static pronunciation dictionary plays a key role in the speech recognition accuracy. Modification should be performed in the dictionary, which is used in the decoder of the speech recognition system. This modification reduces the number of the confusion pairs which improves the performance of the speech recognition system. Language model scores are also varied with this modification. Hit rate is considerably increased during this modification and false alarms have been changing during the modification of the pronunciation dictionary. Variations are observed in different error measures such as F-measures, error-rate and Word Error Rate (WER) by application of the proposed method.
