Identify itself by voice? (own wav file)

Hi, just installed AllStarLink v3 and got everything working.
But I’m wondering instead of the link identifying itself once an hour with CW, can it be made to identify itself by voice? For example, if I have a wav file that says welcome to this allstar link…blah blah!
Have searched and tried different things but nothing seems to work! Anyone other than me interested in how to solve this?
The reason is that hams find my link but don’t understand what it is and use it!
So an audio file describing it’s allstar link, frequency, subtone and owner would be cool!

Okay, is this the right way to export an audio file from the Audacity application?
Export audio file, other uncompressed files > Mono > Sample rate 8000hz > RAW (headles-less) > encoding to U-law. This will create a file called test.raw

And is it right that I change the Rpt.conf file.
I tried this, to change so that the link identifies itself once an hour with an audio file instead of CW audio?
idrecording = /home/asl/test.raw insted of idrecording = |iCALLSIGN

Or am i completely wrong about it, maybe I have to put the file somewhere else? Or do I have the wrong file type, maybe it should just be a 16bit/800Hz PCM wav file instead?

ulaw works, however, I tend to use raw PCM, 8000 hz, 16-bit mono, signed, Little-enndian. If using raw PCM, rename the files to *.sln. In any case, remember to not specify the file extension anywhere Asterisk looks for it, such as in rpt.conf.
For example, change
idrecording = /home/asl/test.raw
to
idrecording = /home/asl/test
where the file is either test.sln or test.ulaw.
Make sure the asterisk user can read it.

I don’t know where you are, but identifying once an hour seems a bit long. In the U.S. a station is supposed to ID every ten minutes. In Canada, every 30. Different in other places.

Finally… It worked perfectly now.
Now i just need to check how often the link should identify itself, before i make it available to my like-minded hams.
Thanks for the help Patrick!
