I'm using renshuu and one feature I find incredibly helpful is when I click the bullhorn and it pronounces the word for me so I can hear it. It's really key to helping me learn the words. But I can't figure out how to get it for any of the Kanjii readings. I'm sure I'm being dense, can someone please explain how I can do this? Thanks very much.
Individual kanji readings don't have audio, because most of them are pronounced several different ways and you would be bombarded with a lot of audio that's just not as helpful as hearing the reading in the context of vocabulary. (And that's a lot of extra audio for Saki to record)
Instead, the area with the list of kanji readings is clickable and will search for them in the dictionary, and you can set the kanji area to list common vocabulary under it, and then listen to the audio for those words.
Think of it this way: when you learned the alphabet, you didn’t learn how the letters were pronounced, you learned the names of the letters. In order to understand all the ways a letter is pronounced, you need to learn words using the letter.
So for example, the letter G is pronounced differently in grant, giant, rough, and rouge. Kanji work the same way, except that they are so old that they’ve had the time to acquire many names, so many that it isn’t really even a useful concept, especially since many of the names are shared.
Just as an aside: actually, a lot of phonetics learning materials (I'm helping teach my son right now) do exactly that - they introduce words using only certain pronunciations of the letters, and then expand past that with combinations, etc.
With the ABCs, though, there are soooo many ways to say them, that it is not possible to do that exhaustively - basic pronunciations are useful at first until you switch to acquisition through words.
As to the OP - it may be that we add audio to the kanji readings at some point. However, given our limited time, I feel that expanding out the audio for words and sentences is still more useful, and we'll continue to do that for the time being.
