[Espeak-general] Some questions about espeakedit

[<hgn...@ya...>]

The following text is from

-----
Use an existing vowel file as a guide for how to set
the amplitude and length of the keyframes. At the
right of each keyframe, its length is shown in mS and
under that is its relative (RMS) amplitude. The second
keyframe should be marked with a red marker (use
CTRL-M to toggle this). This divides the vowel into
the front-part (with one frame), and the rest. Use F2
to play the sound of the new vowel sequence. It will
also produce a WAV file (the default name is
speech.wav) which you can read into praat to see
whether it has a sensible shape.

Isn't length and amplitude at the left of each
keyframe?

What's the value of Hz on the top-right corner of each
keyframe mean?

What's Marker mean? If I don't toggle marker, it don't
sound normally. Could anyone give me a more detail
explain.

Thank you!
