Sending voice message from file on PC

Hi,
Firstly, this is a great tool.
I have a *.AMR voice message saved on my local drive and I want to send it to one of my contacts.
Looking through the code I can see there is a VoiceMessage function, but can't figure out how to use it with a local file. Any help very much appreciated.
KR,
Lawrence.

@lwykes Now we can't send voice message directly with these apis. But you can send it as a file message.
