The length and percentage amplitude adjustment controls are in the
"Spect" window which is to the left of the spectrum window.

The actual amplitude value is shown at the top-right of each keyframe.
When you adjust the "% amp" spin control then the amplitude value in
the currently selected keyframe changes.

That's the pitch of the original sound recording.
You can ignore it.

For a vowel, set the Red Marker(control-M) in the second keyframe.
When eSpeak makes sound from a vowel, it considers it in two parts. 
The Red Marker splits the front-part from the end-part.
Currently eSpeak automatically makes the front-part (i.e. between the
first and second keyframes 45 mS).
