description

Automātiskā runas atpazīšanas sistēma (no angļu valodas automatic speech recognition – ASR) ir tāda sistēma, kas cilvēka izrunātos vārdus pārvērš tekstā. Tās pamata divas sastāvdaļas ir akustiskais un valodas modelis. Darba mērķis ir detalizēti apskatīt metodes, ar kurām tiek trenēti valodas modeļi, kā arī pārbaudīt, kā labākās no tām darbojas latviešu runas atpazīšanā. Valodas modeļu trenēšanā tika izmantotas brīvi pieejamās rīkkopas KenLM un SRILM. Runas atpazīšanas eksperimentos, kuros tika izmantota brīvi pieejamā runas atpazīša- nas rīkkopa Kaldi, tika identificētas problēmas, kādas rodas, valodas modeļus pielietojot runas atpazīšanai klasiskā veidā. Modificējot klasisko pieeju, ar kuras valodas modeļi tiek izmantoti runas atpazīšanā, tika iegūti būtiski uzlabojumi runas atpazīšanas kvalitātē.
