The study aimed to analyze females and males in mixed-sex conversations and same-sex conversations using cooperative speech, competitive speech, interruptions, and similarities and differences in their communication styles in the Tv series modern family. Men and women are said to use different speech styles regarding cooperative, competitive, and interruptions. I used three conversations taken from Season 1 Episode 24, Family Portrait, for mixed-sex conversations in my analysis. I also used three same-sex discussions taken from Season 3, Episode 5, Hit and Run, and Season 1, Episode 11, Up all night. The result shows similarities in both same-sex and mixed-sex conversations regarding women’s use of cooperative speech styles and men’s use of competitive speech styles and interruptions. However, my study found differences regarding women in mixed-sex and Same-sex conversations when it comes to interruptions. Women interrupt in mixed-sex discussions and not in same-sex discussions. Therefore, my analysis of the series modern family is in line with previous research on gender and language.
