Determine your starting level of Arabic language knowledge. If you already know a great deal of written or spoken Arabic, you will want different resources than if you are just starting out.
Practice sounds specific to the Arabic language. Certain common sounds in Arabic, such as the "ta" and "kh" sounds will require practice if you want to say them correctly. Seek out sites with audio pronunciation of the Arabic alphabet and repeat the sounds you hear.
Listen and repeat individual Arabic words. Even if you can pronounce the basic Arabic sounds, it may require some practice to speak the words. Many language websites offer audio pronunciations of the words in their lessons, which you can listen to and repeat.
Watch and listen to video content available from Arabic-language websites. Most major world news sources, such as the BBC and al-Jazeera, offer news content in Arabic. Open audio and video files on the sites to hear the Arabic. If you have trouble understanding the Arabic, look for the same news reports in English as a reference.
If you want to learn how to speak any of the many Arabic dialects, your best source for free files to help you is YouTube. Search the site for videos from countries like Egypt, Morocco or Iraq. Listen to the language and compare it to the formal Arabic heard from news sites.
