You may have to suffer vocal fatigue if you speak a foreign language and the fatigue may further lead to vocal disorders, according to scientists.
20 Finnish and 23 English speakers were asked to read a text in their native language and then in foreign language by the researchers from University of Tampere in Finland.
Spontaneous speech and text reading samples of English and Finnish were recorded in native and foreign languages.
People’s subjective views were asked with the help of questionnaire on changes in voice caused by transition from speaking the native language to speaking the foreign language. The samples were then acoustically and perceptually analysed.
According to findings of researchers, changes in voice, especially in pitch are caused by foreign language. The subjective ideas were supported by acoustical and perceptual analyses.
They found that the voice was in many cases more pressed in the foreign language than in the native one.
Pressedness adds loading of the vocal folds. Also, dose measurements of vocal loading a trend towards more loading in the foreign language was found, researchers said.
“Speaking a foreign language and the changes it causes can have far-reaching consequences, as more pressed voice production can result in subjective symptoms of vocal fatigue and overloading of the vocal folds,” said Kati Jarvinen from University of Tampere.
“Overloading of the vocal folds may cause voice problems and actual voice disorders,” Jarvinen said.
