Listen to English from as many different sources as possible.

Hola Nubia, el mejor método que me ha servido en lo personal es el de exponerse el mayor tiempo posible al idioma. Para esto debes ver series, películas, o contenido en general que te llame la atención en inglés, y poner SUBTÍTULOS EN INGLÉS, incluso si al inicio no entiendes mucho, poco a poco te vas acostumbrando y tu cerebro se adapta a la fonética del idioma al igual que al lenguaje escrito. Para aprender más rápido te recomiendo que cuando estés viendo tengas un cuaderno para anotar las palabras que no entiendes (no es necesario anotar todas, sino las más importantes). Primero escribes la palabra en inglés y al lado puedes poner la traducción en español!

Hi Nubia, In my experience that could be also because you need to focus more on pronunciation. Sometimes mispronouncing words in English makes it hard to understand what people are talking about as you are not able to recognize those sounds! My advice is to expand your vocabulary and check also the pronunciation in any good dictionary.

1. Increase your vocabulary 2. Do more listening practice Listen to things you care about or are interested in or already know something about. When you have context it makes picking out words and following along much easier. Do listening practice with subtitles and without subtitles. I'd also suggest that you listen to the same audio over and over until you know it very well.

Another simple way of improving your listening skills is by making transcripts. After listening to an audio several times, try re-write the text, part by part. It will help you a lot because you are making a big effort to undesrtand every part of the audio, identifying specifics sounds or phrases in a text. Of course, you must listen to audios according to your English level.
