Hi gadgetmax, yup I ran into this problem too. I ended up having to create a text-only version of my fixed format epub just so I could test all the narration thoroughly, tweaking some of the clipstarts by adding a few milliseconds until the word lit up, to ensure everything was highlighting. Then throwing all the smils back into my original epub and rebundling. A perfectly good waste of a weekend. Pretty frustrating, seems like the new iBooks was a bit rushed getting out.
iBooks 3 works just fine for my Children's Book. What I did in Audacity was highlight my first word, made a label. Then I highlighted my second word up until I saw the yellow line and made a label for my second word. I did this technique for all my words.
When doing the .smil file there were no gaps (seconds) in my recording. For instance:
clipBegin="0.000000s" clipEnd="0.766258s" clipBegin="0.766258s" clipEnd="1.033288s"
By having the clip end and begin for next word, iBooks 3 knows where the next word starts and will highlight it.

Hi JudithT, it's very odd. That was how all my words were set up as well i.e. no gaps. One thing I could think of which may be different, is that I added a spacer timing of about .3 seconds at the beginning and end of each page. I had no problem in previous version of iBooks with that setup however. It was only until I updated to iBooks3 that it started happening, and there seemed to be no pattern to it that I could detect.
What I did when I wanted extra timing was to add silence of 2 seconds and include it in my first Labeled word. And if I wanted extra time at the end, I had extra silence at the end of the audio recording and then included it with the last word on my .smil file.
You might try that and see if you get a more consistent result.
I have CSS animation in my Children's Book and only words on my first .xhtml page of a two page spread. The animation happened on the second .xhtml page so I added enough seconds to the first page .smil file to have it keep going until the animation played out on the second page. It worked very well. And the page will not automatically flip until the .smil file tells it to be done.
Tim, after re-reading what you wrote about spacer timing, we might be saying the same thing. I have an Original iPad I'm testing mine on but I'm pretty sure I have the new iBooks 3 on it.
I do know when I was originally testing the read aloud for my eBook, it would skip a word. Usually when I closed and reopened the book on my iPad, it would resolve itself. Other than what I mentioned, I have no other recommendations.

Hi Judith, I noticed you mentioned you had all your text on only one side of the two-page spread. I had my text on both sides of a two-page spread so maybe that had something to do with it. Although if I remember correctly, the unhighlighting occurred randomly on either side of the page. Other than this, and I didn't have any CSS animation, I can't really see a difference. I'm going to do a test and remove my text from one side of the spread, see if that changes anything, will let you know how I get on.
I had a look at the Apple's own Fixed Layout Example 3.0. On page 5, the 2nd 'shall' fails to highlight. I unzipped the .epub and found this is word84. The word prior to it has a clipEnd of 0:00:32.233 which is exactly the same as the clipStart for word84. Thus no gaps, yet it is failing to highlight. There's no explicit pause stated at the start or end of the .smil either. It seems to be quite random that this is happening. Note this is the only word in the entire epub which is not highlighting, at least as far as I could tell. So I would think it is entirely possible that you could end up with an epub with no problems if you are lucky enough, but this is definitely a bug in iBooks 3.0. I would just say test your read-alouds thoroughly and tweak your clipStarts where necessary, until this problem is fixed by Apple.
