I don't have my 6600 charged to try, but have you tried loading a WAV-file? Perhaps the Sound module does not support MIDI files.

hi jethro.fn:
thanks for your reminder,wav-file works well,however,another funny problem
araised,when I use this code directly,it works,but when I put this code in a function,it failed to make a sound
for example:
#this code works well
import audio
from audio import *

#msg.wav exists
file = "c:\\msg.wav"
s = Sound.open(file)
s.play()



######but the code as folllow failed:

import audio
from audio import *

#msg.wav exists
def sound_play():
    file = "c:\\msg.wav"  
    s = Sound.open(file)
    s.play()

sound_play()

The problem is that Sound object "s" is local to your function and it gets deleted as soon as it gets out of scope when the function ends. s.play() is an asynchronous function, i.e. it starts a sound and returns, without waiting for the sound to end. When "s" is deleted, the sound stops.

You need to wait for the sound to end in sound_play() or make sure "s" is not deleted prematurely, for example:

import audio
from audio import *

s = None

def sound_play():
    global s
    file = "c:\\msg.wav"
    s = Sound.open(file)
    s.play()

sound_play()

In the code above, "s" is a global variable and only gets out of scope when the program ends.

buddy ,thanks for your kindness
it works now.

I've got a question concerning the set_volume command,

This code works fine:

def sound_play():
		global s
		s.set_volume(SetupForm.getVolume())
		s.play()

but how can I change the volume of the audio.say command?

audio.set_volume(5)
audio.say(unicode(cid))

fails.

And can I control the speed of the reading? And what about volume? And how to put in pauses?

And finally, my programm stops running as long as the duration of the speech output. How can I make I application do not wait untill the speech is finished?
