Review of VOICE OF AMERICA (VOA)
Web, No pronunciation scores, Free, Intermediate
VOA has many audio files and 800 captioned videos in "Special English" so learners can practice. The vocabulary is large, and there are no pauses when beginners can repeat words or phrases, so these are for intermediate learners.

They also have 3,000 videos in standard English with subtitles. 400 of the VOA videos are on English Central, where learners can slow them down and get pronunciation scored, though only one of these is Special English, so they require even more vocabulary.

VOA also has vocabulary lists, where you can listen to pronunciation of words, definitions and examples, though without pauses. It also has many pages to read about various topics in English.

The basic list of Special English has 1,500 words, and appendices add numbers, countries, cities and other topics. This does not count verb conjugations, irregular plurals like "women," and multiple meanings, so 2-3,000 word forms must be recognized in all.

VOA refers people who want to improve their English to English Central and GoEnglish.me, both of which are for intermediate learners.

Review of DYNAMIC ENGLISH
Web, No pronunciation scores, Words, Free, Intermediate
VOA has worked with Dyned to create podcasts for intermediate English speakers to practice. VOA broadcasts them regularly. They are purely audio, but not introductory. They have long English introductions, go fast with little time to repeat, and diction is colloquial (N'York, th'United States, h'lo).

Review of GoEnglish.Me
Web, Pronunciation scored, Words, Free, Intermediate
This site, sponsored by Voice of America (VOA), teaches English for speakers of Chinese, Farsi, Indonesian and Russian, lets you hear and record each phrase, and marks you pass or fail.

The site spells short sentences in English and in the native language chosen, says them in English, records you, and gives pass or fail on each sentence. You can repeat as often as you wish, but they do not break the audio into separate words or syllables, so it would be very difficult for complete beginners. Scoring is also hard: even as a native English speaker I often failed, with no indication what I pronounced wrong.

_Review of EnglishCentral.com
Web, Pronunciation scored, Partly free, Intermediate
This site has many videos in English, with captions. You can repeat phrases, slow them down, and get your own pronunciation scored by the computer. When you slow them, the audio is still very clear.

The score on each phrase appears precise ("11 of 21 pts"), but does not say what needs improvement: vowels, beginning, end, etc. Scoring is gentle: I did well unless mispronouncing on purpose.

Hundreds of videos are free, or you can pay $10/month or $80/year for more. Some are listed as "starter courses," but even these are fast intermediate English, with no explanation of the meaning if you do not already know English, definitely not for beginners. Many have background music, which makes the intermediate English even harder to understand.
