Bugzilla Bug 136600

the "high quality" voice in freetts, called "alan" works with errors or simply
fails to work at all.  "poorly" means that freetts will produce about 1/4
second of garbled audio followed by a bunch of error messages:

 # freetts -voice alan -text "This is a test."
System property "mbrola.base" is undefined.  Will not use MBROLA voices.
System property "mbrola.base" is undefined.  Will not use MBROLA voices.

this happens whether run as root or as a normal user.  googling for this error
returns nothing useful.

i can run this, and it works flawlessly:
 $ freetts -voice kevin -text "This is a test."


here is some info about the voices installed on the system.

Yeah I can see this problem too.

Adding java to the cc for this bug.

Java team,

can someone take a look at this?

Thanks,

William

I was able to reproduce this error using upstream bin packages and the
documentation states:

Currently, the distribution comes with these 3 voices:

    * a low quality, unlimited domain, 8kHz diphone voice, called kevin
    * a medium quality, unlimited domain, 16kHz diphone voice, called kevin16
    * a high quality, limited domain, 16kHz cluster unit voice, called alan

I believe limited domain means, limited vocabulary.  Note alan can say words
such as "1" and "one".

Therefore either this isn't a bug, or it is an upstream bug.

Due to the information in comment #4, I am closing this bug.  It
appears that this voice has limited functionality, and this is how
upstream intended it to work.
