Re: [css3-speech] voice-balance and azimuth

I have (majorly) re-formulated the prose to better express the relationship between the physical setup (user sound system) and the authored intent. I also added a section explaining the mapping to azimuth angles.
Please kindly review (as soon as you can):

Many thanks!!
