Sample Speeches are useful and helpful in a couple of ways: Firstly they give you a great idea of what an occasion-specific speech should look like and what it should include/avoid. Secondly, it gets your brain working by stimulating your thought-process and providing you with ideas/content for your own speech.
I usually recommend not simply taking any of these sample speeches and delivering them Verbatim (copy & paste style public speaking), by simply changing some of the names and details, but leaving everything else intact.
Ideally, these sample speeches should help you with writing your own speech! But only a better one now since you now know what kind of content to focus on, and what to include/exclude in your speech.
That's why I've gone a step further by analyzing all of these sample speeches for you and including some brief notes after each one. By reading these you'll gain valuable insight into the dynamics of your specific speech - it should simplify and streamline the process.
See the categories below and click on the links (the numbers next to the pictures) that apply to you. Most of the categories contains more than one different sample speeches (on its own page), each providing a different angle or approach to the same kind of speech.
I recommend looking at all of them in your category. This will give you a broader overview and will be especially useful if you'll be writing your own speech.
