Test ehko error

[beew]

Hi,

I am able to compile and install ekho, but running test_ekho produced these errors towards the end.

Festival speak: 'English is easy. ' in voice of voice_kal_diphone
SIOD ERROR: the currently assigned stack limit has been exceeded

EkhoImpl::speechDaemon synth2 end
Assertion 'p' failed at ../src/pulse/simple.c:386, function pa_simple_drain(). Aborting.

ekho was configured with

./configure --prefix=$HOME/opt/ekho --enable-festival --with-mp3lame

OS is Ubuntu 22.04

Thanks

If configure without festival

Tibetan data is removed by default. test_ekho fail to run without it. I have commented out test for Tibetan and commited.

Festival support is a bit hard to build. Please don't enable-festival unless if you are familiar with Festival.

You should be able to run ekho even test_ekho fail in the above cases.
