ENThe aim of this pilot study is to find out whether a secondary rhythmical stress exists in the connecting vowels of the standard Lithuanian compound words analyzed. To reach this aim, 12 respondents of both genders (6 males and 6 females) and different ages (between 25 and 50) were asked to record 12 sentences with Lithuanian compounds. Each respondent recorded the sentences 3 times. Afterwards, connecting vowels that are two syllables away from the main stress were compared with those that are one syllable away by the following parameters: the duration, the average and maximum pitch (male and female voices separately), and the average and maximum intensity. Results of this pilot study have shown that a secondary rhythmical stress does not exist in the connecting vowels analyzed. Keywords: secondary rhythmical stress, connecting vowel, compound word, standard Lithuanian language.
