摘要：Formants belong to the acoustic parameters addressed by the research of emotional speech.The aim of the present study was to find out how,if at all,the utterance emotion of Estonian read emotional speech may affect short vowels and articulatory precision.The acoustic basis of the study was the Estonian Emotional Speech Corpus (EESC) of the Institute of the Estonian Language.The Corpus contains non-acted speech (journalistic passages) read by a female voice,which have been segmented into sentences,words and speech sounds.The emotional colouring (anger,joy,sadness) or neutrality of the Corpus sentences has been ascertained by perception tests.The research material consisted of such Corpus sentences whose emotion or neutrality had been confirmed by more than half of the listeners.Three short vowels,a,i and u,were picked from those sentences and subjected to formant analysis.Those three are frequent Estonian vowels defining a triangular vowel space (a being a low back vowel,i a high front vowel and u a high back vowel) enabling a fine description of a speaker’s articulatory precision.To solve the research question,measurements were conducted on the first and second formants (F1 and F2) of the short stressed vowels a,i,u as segmented from read Estonian emotional and neutral speech.The results showed that when measured pairwise (partners including neutral sentences) significant differences are revealed between the F1 means of a and i.F2,however,plays no significant role in emotion differentiation.Vowel reduction and articulatory precision were investigated by using Euclidian distance.According to the results,in the case of angry and joyous utterances articulatory precision was more or less the same as in neutral ones,while a a fall signalled sad utterances.
其他摘要：Formante peetakse üheks emotsiooni peegeldavaks akustiliseks parameetriks – kõneleja emotsionaalne seisund võib põhjustada muutusi häälikute formantstruktuuris.Uurimuse eesmärgiks on teada saada,kas ja kuidas mõjutab lausungi emotsioon eestikeelse etteloetud emotsionaalse kõne lühikesi vokaale ning ettelugeja artikulatsiooni täpsust.Selleks mõõdeti etteloetud emotsionaalse ning neutraalse kõne lühikeste rõhuliste vokaalide a,i,u esimest ja teist formanti.Uurimistulemustest selgus,et emotsioonipaariti (k.a neutraalne kõne) on statistiliselt olulised erinevused olemas vokaalide a ja i esimeste formantide (F1) keskmistes.Teine formant (F2) emotsioonide eristamisel olulist rolli ei mängi.Vokaalide redutseerumist ja artikulatsiooni täpsust uuriti eukleidilise kauguse arvutamise abil.Tulemused näitasid,et viha- ja rõõmu-lausungites jääb kõneleja artikulatsiooni täpsus võrreldes neutraalse kõnega enam-vähem samaks,kurbuse-lausungites see aga langeb.*.
