20.500.12556/DKUM-91935 Vpliv napak razpoznavalnika govora na kakovost strojnih prevodov v sistemih prevajanja govora v govor magistrsko delo The impact of speech recognition errors on the quality of machine translations in speech-to-speech translation systems Magistrsko delo analizira vpliv napak avtomatskega razpoznavalnika govora na kakovost strojnih prevodov v sistemih prevajanja govora v govor. S prevajalnikom smo prevedli več izhodov razpoznavalnika govora, ki so se med seboj razlikovali v kvaliteti razpoznavanja, kot referenčne prevode pa smo vzeli prevod nabora povedi, ki je bil uporabljen na vhodu v razpoznavalnik. Tipi napak, ki smo jih obravnavali, so bili: vstavljanje, brisanje in zamenjava besede. V nadaljevanju smo jih še podrobneje razdelali glede na besedne vrste in obseg spremembe. Vpliv napak na kakovost prevodov smo ocenjevali z metriko BLEU. Ugotovili smo, da določene vrste napak bolj vplivajo na kakovost prevoda kakor druge. This master's thesis analyzes the impact of automatic speech recognition errors on the quality of machine translations in speech-to-speech translation systems. We used the translator to translate several speech recognizer outputs that differed in recognition quality, and as reference translations we took the translations of the set of sentences that was used at the input to the recognizer. The types of errors we considered were: insertion, deletion, and word substitution. We further elaborated on them in more detail according to word classes and the extent of change. We assessed the impact of errors on the quality of translations using the BLEU metric. We found that certain types of errors have a greater impact on the quality of translation than others. razpoznavanje govora strojno prevajanje napaka razpoznavalnika nevronske mreže BLEU speech recognition machine translation recognizer error neural networks BLEU true true false [K.
