MARY TTS 5.0 is better supported by automated tests than any previous version of MARY TTS, but it may well be that in practical use some hiccups will appear that have not surfaced in testing.
Therefore cautious users are advised to treat this as a beta release.
Installing MARY TTS is now performed by simply unpacking the
zip archive at the target location.
No clicking through installer pages anymore.
In particular, it is now trivial to install MARY TTS on a server without a GUI connection.
The component installer,
bin/marytts-component-installer.sh, still uses a GUI;
see issue #43 for a workaround.
It is now possible to use MARY TTS, with HMM-based voices at least, simply by placing the right files into the classpath.
For example, to use US English voice
cmu-slt-hsmm in your own code, add the following jar files to your classpath:
marytts-server-5.0-jar-with-dependencies.jar marytts-lang-en-5.0.jar voice-cmu-slt-hsmm-5.0.jar
marytts-server-5.0-jar-with-dependencies.jar you can also include the individual dependencies, which can be automated using maven;
the source code on github includes examples for doing this in the
Using MARY TTS programmatically gets a lot simpler with MARY TTS 5.0 through the new MaryInterface API.
The same API can be used to access the TTS components running within the same java process or as a separate client-server setup.
For details, see MaryInterface.
MARY TTS 5.0 includes an implementation of W3C’s Emotion Markup Language as a means of requesting expressive synthetic speech.
The result of course depends on the expressive capabilities of the selected synthesis voice;
try out the EMOTIONML example with the German
dfki-pavoque-styles voice on the demo page.
The MARY TTS source code has been modularized for version 5.0.
The modular structure also makes it easier to see which components belong to a given language:
sub-projects such as
marytts-lang-en etc. contain all code and data that is language-specific.
The updated New Language Support documentation describes how to create a new language sub-project and integrate it into the system.
The maintenance of the list of installable voices has been decentralized:
if you build a voice and wish to make it available to others, you can host it somewhere on the net, e.g. on Google Drive, Dropbox or similar.
For details, see Publishing a MARY TTS Voice.
MARY TTS 5.0 mostly results from the aim to establish sound software engineering practices in MARY TTS development.
Aspects of this include:
