Speech Setting Ruins Audio Timing

I’m struggling with a glitch in Flash 8. I have narration in my flash program, with each audio file placed in the timeline set to Streaming (for better synch than Event).

In the Publish settings, if I set the sound export setting to “MP3”, timing is perfect, just the way I created it. However, if I set the export setting to “Speech”, all the audio’s timing is suddenly way out of synch.

I want to use the Speech setting since it results in good sounding audio at half the file size for the final .swf, but this timing issue makes it non-usable.

Any suggestions?
