TalkEnglish.com is a free website with over 900 lessons and 8,000 audio files to help you learn how to speak English fluently. Most lessons contain clickable sentences that you can click to listen to a native English speaker say that sentence. There is also a free Talk English app available which has extra features such as a click, listen, and repeat functionality, a record and playback tool, and interactive conversation practice lessons.
TalkEnglish.com is not going to win any prizes for pedagogical innovation - it does exactly what it says on the tin. However, the sheer number of lessons and audio files makes it a valuable resource for students who want to improve their pronunciation or listening skills. An added bonus is that the sentences are read by native speakers, not text-to-speech robots.
