Hi,

I'm experimenting with Text to Speech systems, I'm on Slackware 10.2 and I have cam across the following problems

I've sucessfully setup the festival system and associated files and speech tools, now While in KDE 3.5, I run festival it always says
"Unable to open /dev/dsp"
Although no sound application is running, when I shut down X server and in console try the same thing, it works! So how do I use festival in KDE?

The second problem is this:
When I change a voice I always get the following:

SIOD ERROR: unbound variable : f2b_f0_lr_start
closing a file left open: ../lib/init.scm
festival: fatal error exiting.

When I comment the voice change setting in siteinit.scm, its working normal then?
This is what i use to change the voice (simply uncomment the statemetn)
(set! voice_default 'voice_cmu_us_awb_arctic_hts)

Any help will be highly appreciated

Regards

I have not had any problems with festival on Slackware. I installed the speech_tools and festival packages from www.slacky.it and then added some MBROLA voices manually.

When you use it under KDE, are you doing it independently of the KTTSMgr? With the K Text-to-Speech Manager (which uses festival as a backend) you can choose to route the audio through aRts or ALSA, so you should be able to get something working there. And then see if it still gives you problems with voice switching through the kttsmgr.

I've fixed the problem with the unbound variable, it was an issue with just one voice.

I'll try using the KTTsMgr
