The best way to practice speaking is to just speak, without worrying about any of the grammar. You will be understood by a native speaker, and it will help you learn to put words and phrases together. Also, whenever you learn new words and phrases, try and put them in your daily speech. Another thing my sister does is she will listen to music in English and translate it into American Sign Language while listening, which admittedly is a little different than from another language into English; however, it might be worth trying. Best of luck!
