Pay attention to your audience. To effectively adapt your communication, you must understand who you are talking to. Look at things from their point of view and try to adjust to be closer to them.
Determine your relationship with the audience. With a good friend, you will probably be more sincere and cheerful. With the boss, you will need to speak with respect. With the cashier, you can be friendly, but conservative.
Remember that there are personal differences. For example, extroverts like to communicate face to face more than by phone and in large groups. They tend to think out loud. Introverts prefer to speak via e-mail, text messages, and prefer to talk one-on-one. They often need time to think before answering questions.
Conduct an analysis of the audience. Pay attention to age, gender, level of education, values, culture, family structure and the experience of those who make up your audience. This is especially useful when you have to make speeches in an unfamiliar audience.
