Re the shadowing material:
I am currently reading the article about it and it looks good. I am using the ‘Shadowing’ (green) book at the moment (you can find it on white rabbit press) and finding that useful but will come back and look at this afterwards. I am finding shadowing is improving both my listening and speaking, my mouth muscles are getting more used to Japanese (if that makes sense). It is also improving my confidence steadily with speaking.
I can’t comment about anything else on the website though as i’ve not used it but it certainly looks interesting
they give you sentences in English and you have to translate it into Japanese in less than 3seconds, the idea is to be able to repeat the same grammar point over and over again until you can use them without thinking and thus improve your speaking skills. it is free as well!
i am so sorry! i just saw this post! my grammar and sentence structures have really improved, i don’t take too much time anymore to “spit” a sentence when before i was always thinking for too long : does this particule comes here? is this tense correct? where do i put this adverb?..and so on you should give it a try!
