The present study examines the effect of age and gender on global intonational features in a prosodically annotated corpus of spontaneous narrations by adult and adolescent heritage speakers (HSs) of Russian in the U.S. and monolingual speakers of Russian. The study investigates the use of boundary tones (BTs), bitonal vs. monotonal pitch accents (PAs) and frequency of PAs in these speaker groups. The results show that age and gender influence some of the investigated intonational patterns, but not all. Specifically, it was found that female and adolescent speakers in general produce high BTs more frequently than male and adult speakers. Further, female HSs produce more monotonal accents than monolingual female speakers while male heritage and monolingual speakers are similar to each other. Also, monolingual female speakers produce fewer monotonal accents compared to male monolingual speakers. Finally, PA frequency was not found to be influenced by age or gender. The results are discussed with reference to physiological differences between male and female speakers, possible influence from the HSs’ majority language English and possible ongoing change in monolingual Russian that is initiated by female and younger speakers.
