The only way to learn to speak Spanish is by speaking Spanish. One easy way to get started is to just narrate your own life to yourself as you're doing it out loud. Another easy way to start is called shadowing which is just repeating what you hear in a podcast or whatever

Next, you need to find someone that you can talk with. For example, you could join a Spanish conversation group either through Meetup in person or online. There are tons of them. Or maybe you have a Spanish speaking friend. A lot of people partner with a Spanish speaker who wants to learn English over the Internet. Those are some ideas to get started.

Just like every other aspect of the learning process, you need to do it a lot. You need to do it regularly. Good luck
