Expected Behavior

We want to set up Daisy Pipeline 2 with Acapela TTS voice Manon on a windows 10 virtual machine to produce DAISY 3 .

Actual Behavior

SMIL files are generated but no audio file is generated. The log indicate

"org.daisy.pipeline.tts.TTSRegistry - acapela-jna could not be initialized, cause: This version of Acapela doesn't run on Windows.: java.lang.UnsupportedOperationException: This version of Acapela doesn't run on Windows."

Steps to Reproduce

• We installed java11 and Lame thru WinLame GUI.
• We followed the the guide here https://daisy.github.io/pipeline/Get-Help/User-Guide/Text-To-Speech/
• Acapela is recognized by windows after using RegSapi5.bat script.
• tts-default-config.xml is set up as follow :

<config>
	<voice engine="acapela" name="manon" lang="fr" gender="female-adult" priority="1"/>
</config>

Environment

• Operating system: Windows 10 64-bit
• DAISY Pipeline 2 version: 1.14.2
• Interface: GUI

Hi Gautier, The acapela-jna adapter works with Acapela for Linux only.

Thanks Alex, how can we set up an adapter working with windows ?

Hi Gautier. The implementation is for Linux only and requires the libnscube.so library to be installed on the system. I suppose it is also possible to use Acapela on Windows if it has a SAPI interface. I don't know if that is the case. However SAPI voices currently don't work in DAISY Pipeline 2. We're working on a fix for that.

Thanks Bert, my understanding is that we have to set up the config with SAPI, so something like this :

<config>
	<voice engine="SAPI" name="Acapela TTS HQ..." lang="fr" gender="female-adult" priority="1"/>
</config>

Acapela TTS HQ... being the name of Manon voice in windows SAPI engine.

But anyway there is another problem limiting the use of SAPI. We'll wait the Fix to test.
