Listening Resources

Realize the purpose of your listening. You may listen to understand a conversation, get specific information, or do well on an exam. These require different kinds of practice, so use resources designed for your purpose.
Know your own weaknesses. It could be accents, fast speeds, numbers, or something else. Knowing your weaknesses can help you focus on areas that need work.
Listen for more than just the words. Listening for pronunciation, intonation, and even the pauses can help you understand how English is used naturally and improve your own spoken English.
Try 1-2 short audios every day. Regular practice is essential and takes just a few minutes. (Do it on the bus!) The sites below offer a great variety:

Note-taking practice: Take notes while you listen, and then read the text to see if you captured the important information.
Going deeper into a topic: Find a topic you are interested in, and listen/read simultaneously. You can then try to write a summary.
Boosting your vocabulary: Find a topic that you want to know the specific language about. Take note of the vocabulary and then try to use the words in your own sentences. Afterwards, you can review by reading the text.
