A standalone cloud-based installer and wrapper for MaryTTS

Just download the latest source code package from the Releases page (the source code is the installer!) and unpack it anywhere on your system.

The MaryTTS Installer can be used on the command line, by changing to the directory where it was unpacked and running tasks, for example to run install voice-cmu-slt, do:

$ ./marytts install voice-cmu-slt

> marytts install voice-cmu-slt

The MaryTTS Installer uses Gradle, and will first automatically download it if it isn't already installed.

Before MaryTTS can be used, one or more voices must be installed from the cloud. This is done by running the install task with one or more selected voices, for example, to install voice-cmu-slt, change into the directory where you unpacked the installer and run

marytts install voice-cmu-slt

If no voices are installed, voice-cmu-slt-hsmm will be installed by default.

marytts install voice-cmu-slt

marytts list

marytts info voice-cmu-slt

marytts uninstall voice-cmu-slt

Note that this is effectively the same as simply removing the corresponding voice files from the installed directory.

marytts server

or simply

marytts

will start a local MaryTTS server with all installed voices.

marytts --info

or simply

marytts -i

will print INFO level log messages from MaryTTS (and Gradle) to the console.

To get DEBUG level log output, run

marytts --debug

or simply

marytts -d

Of course it is also possible to customize the MaryTTS server's environment by specifying arbitrary properties, just like when invoking java directly.

All downloaded artifacts for MaryTTS and its voices are cached in the local Gradle home ($HOME/.gradle by default) so that they don't have to be downloaded again if a voice is uninstalled and then installed again, or if MaryTTS is also installed into additional directories. Note that this cache also stores the packaged data files for unit-selection voices, which can be several hundred MB in size.

In order to free up storage space, it is possible to delete the cached files for an individual voice, like so:

marytts purge voice-cmu-slt

Of course this means that any subsequent installation of the corresponding voice will require downloading the artifacts again. Note that purging a voice's cached files will not uninstall it.

It is possible to customize the location of the download cache by running the install tasks with the --gradle-user-home (or simply -g) parameter; i.e., to use some (possibly new) directory named download as the download cache, run

marytts --gradle-user-home download install voice-cmu-slt

or simply

marytts -g download install voice-cmu-slt

Note that this will also first download Gradle itself into the custom download cache.
