(For those that haven't read the blog entry, I was ill and lost my voice completely for some time.)
I would say that things are starting to change with regards to voice and pronunciation. The recent rise in call centres exposed a serious issue, where centres based in places like India often found that speakers there were not easily understood by customers in places like the US and the UK. This has led to a rise in places offering Accent Reduction and focusing on sounds to a much greater extent than before. The massive increase in communication has also led to calls for people to teach the different pronunciations non-native speakers may have as a skill, rather than just concentrating on imitating native speakers. Nowadays, it is far more common to have students from one part of the world listen to speakers from another and to try to deal with the issues arising.
I wouldn't say that we have got where you would like us to be, but things are changing because modern communication requires it. It's acquiring a greater importance and this involves a greater understanding of how we use voice.
