Great website! My only issue with it is that for people learning English and really trying hard to get the grammar right (and that is an extremely important goal in learning any language - believe me) - your sentences can be quite confusing.
This is because you often leave out the subject pronoun as in “went to the gym” - when you mean “I went to the gym”. I understand you are trying to emulate very fast colloquial speech but in that case people do in fact say “I went to the gym” - they just “eat” the “I” so that it is hard to catch.
Similarly you transcribe a lot of slang phrases like “gonna” and “wanna”. My view on this is that learners will think that this is the proper spelling of these words and then write them in IELTS tests and the like - and get marked down big time!
In reality in English all words get distorted in pronunciation according to where they stand in a sentence - whether in a stressed or unstressed syllable - or whether the speech is conversational or declamatory (like a news reader). This does not mean that we change the spelling when all the letters are not pronounced exactly as written.
I think you would do better to write the sentence correctly and then put the transcription of the pronunciation in brackets.
eg., I want to (wanna) see that movie.
Anyway keep up the good work. You amaze me with all the great expressions you have isolated for teaching. They are so much part of the furniture for most of us that we forget they are there! Well done!
