When we talk about a speech, we mean a statement made by a person with a certain purpose, for example, to persuade someone, convey important information, or even entertain an audience. It can be an official presentation at a conference or a more casual speech at a festive party. A speech is something that adds special meaning to words, making them impressive and impactful.
In slang usage, a speech is when someone speaks passionately or emotionally, but sometimes also too long. For example, when a friend starts telling a long story about their weekend adventures, one might jokingly say: Wow, now that's a real speech!. So a speech is not only official addresses but also any emotional performance that is memorable.
Speech (speach) from English - statement.
