[Athen] Question about Save As DAISY

I haven't used the TTS Narrator functionality in the Save As
DAISY plug-in extensively, but I can tell you that the plug-in suffers
from some memory leaks. Generating a 175 page DTBook XML file should
only take a minute or two. In one of my latest exports the plug-in was
still stuck at 100% complete after more than 24 hours.

After rebooting and clearing my RAM, the export took only a few
minutes. If you find that your CPU usage isn't changing for a few
minutes, I would suggest trying your export after a reboot.

Creating TTS speech for your DAISY book will take a long time.
2.5 hours seems about right for a 400 page book considering that the
playback time can be much longer than that.

How are the DAISY books being read? Do you really need the PC to
generate the speech in advance? Could you use the DAISY pipeline to
create text-only filesets from your DTBook XML instead of embedding the

Good Luck,

Subject: [Athen] Question about Save As DAISY

Hi all,

I have been playing with the Save As DAISY in MS Word and have a
question about how long it can take to create a 450 page book. I choose
to create a DAISY book (as opposed to just the XML version) and the
DAISY Pipeline TTS Narrator began running.

So far, the system has been running for about 2.5 hours. Is this a bit
excessive or is this expected? Most of my samples have been done on
short 10-20 page documents, so I don't have a great reference for a much
longer book.

I am working on a virtualized Windows 7 system with 2GB RAM dedicated to
the Windows 7 instance (CPU is 2.8 Ghz Intel Core 2 Duo). The JAVAW.exe
process has maxed out the CPU usage at 98%.
