Additional Include Directories (from C/C++, General): This path should be set to "C:\Program Files\Cepstral\sdk\include".In addition you need to verify the following properties for mod_cepstral.c (right click mod_cepstral from the Solution Explorer on the left hand side and select "properties"). Scroll down until you see mod_cepstral and select the Bulid flag. Right click the FreeSWITCH solution from the Solution Explorer in VS and select Configuration Manager. Once the SDK is installed you'll need to make sure mod_cepstral is selected to be compiled (not on by default). You can, however, obtain an evaluation copy Contact Cepstral Support with subject line "Cepstral Windows SDK". In order to compile mod_cepstral.c under Visual Studio C++ you must ensure the Cepstral SDK is installed on your build machine. The '15' in the above example means 15% of default volume.įor other SSML tricks check out the examples on Cepstral's support site. You should now be able to use something similar to the following in your dialplan You must define an environment variable SWIFT_HOME in the shell where you run fs, otherwise you won't hear any audio.
If you don't use the default install dir (/opt/swift) you will need to modify `src/mod/asr_tts/mod_cepstral/Makefile` You can also use a Cepstral voice with a language other than English without editing any files. Enable mod_cepstral in the file by uncommenting.Edit nf and uncomment the line: asr_tts/mod_cepstral.Define SWIFT_HOME to point to install root (e.g.Add /opt/swift/lib (if you chose the default install) to end of file /etc/ ld.so.conf.Follow prompts (recommended add: export SWIFT_HOME=/opt/swift to your FS user profile).tar xvzf Cepstral_Allison-8kHz_i386-linux_6.0.1.tar.gz.Each voice comes with the library, so the SDK is not needed.
One such product that comes to mind is Jimmy Mancini's TTS Video Studio, which can produce a sound file.
seconds etc.Īnother option would be to consider some of the recent TTS video software that has been released, while I have not seen any official written documentation backing them up, a couple of the producers do say the voices can be used commercially on public channels. If you don't need a ton of TTS "time", you can find a few commercial broadcast TTS providers that will allow you to purchase by the minute or in blocks of minutes. If you have any further questions, then just get back to me.
A commercial license would be £99 per voice per year and an audio broadcast license would be £395 per voice per year. If you wished to use the voices for commercial use, you would need a commercial license and an audio broadcast license to permit you to redistribute the audio with your animations.
