YES, I agree that speech context can influence one's behavior towards ourselves and other people because the proper use of tones, choice of words and the theme of our speech is directly related to our audience. For example, if we are making a speech about our country, we should be sympathetic and empathetic towards the struggles of the people. When talking to our parents or older people, we use a formal speech tone and use formal words. When talking to our friends, we use casual tones and common jargons thus, we become more comfortable talking with them.
