accurate timings for slide changes

I am teaching reading. I want lyrics to change in time with the music but a
full second is too long in some cases. How can I change slide transition
times to fractions of a second?
 
Are you referring to the advance slide timing?
First, you will need to set the timing to automatically advance after 00:00.
Next, you will need to use delay.
Check out slide delay tutorial here (under "Delay before Slide Advances –
Method 2"):

PowerPoint is not good at syncing with sound so it will never be perfect BUT
....
you can get slide timings of less than 1 second

Set the timing to zero seconds and place a small shape OFF the slide so it
isn't seen. Give this shape an entrance or exit animation of very fast this
will give 0.5 second transitions. In the timing tab you can manually change
the 0.5 seconds to anything you want.
 
kendall,

While it's possible to set a lower transition time, it won't matter much as
PPT is not known for accurate timing. On a fast machine it will happen
quickly, on a slower machine not so quick. It really does depend on the
hardware and how many times you have ran the presentation.

Try this experiment to see what I mean. Close PPT, re-open and run the
presentation. Time how long it takes to run. Now run it again and re-time.
You will see a significant difference because PPT is caching parts of it.

Yes, I have noticed changes in timing from show to show. If I were to save
this as a movie, would my timing be more consistant? This would probably make
the file size huge, though. I keep the shows simple (no animations) to avoid
this sort of problem. What is PPT "recognizing" differently each time?
Can a foot switch be added so that I can advance slides while playing guitar?
 
Excellent answer, thanks! So for a 5.4 second change I should enter 5 seconds
and add a .4 second transition?
Also, do you know of a foot pedal that I could use to advance slides while I
play guitar?

There is no native way to save a presentation to a mocie. I'd suggest
looking at Cantasia and doing a screen capture.

Depends on your hardware and what PPT "thinks" should be cached to create a
smoother presentation.

Never seen it done but I suppose you could treat the switch as a serial port
device and with some code do what you want.
 
For a 5.4 second change add an entrance animation of 5.4 secs and leave the
transition ar zero

Transition time is total time of transitions OR the entered time whichever
is longer.

Put your mouse on the floor? Maybe some doublesided tape to keep it from
skittering off into a corner.

You can also just type in the time you want manually rather than using the
spinner.

00:01.5 for example for a 1.5 second advance.
PPT won't display the fractional values in the slide sorter (instead of 1.5
it'll show 2) but it should play back as accurately as can be expected from PPT.

A 20-slide show set to 1.5 second transitions plays back in 30 seconds here.
