Java Standard Edition SE is a free software bundle that provides the Java Runtime Environment and the libraries and components you need to display a wide range of programs and Web content on bit Windows PCs.
It includes the Java plug-in for Web browsers and Java Web Start for deploying standalone apps written in Java over the Internet or other networks.
Java SE Version 7 Update 55 addresses 37 security vulnerabilities. You probably need it: Lots of Web sites and programs depend on Java to run. Up-to-date Java libraries and components keep your content fresh. Security issues: Some computer security experts have raised warning flags about vulnerabilities in Java and its components. Java 7. What's up with 8? A major update to Java SE, version 8, has also been released. If you change this, the demos may not work properly. Once you've downloaded and unpacked the FreeTTS binary distribution, perform the following steps:.
We have provided a number of demonstration applications that use FreeTTS. We highly suggest that you use these as examples for how to create your own applications. The output will be placed under the bld directory. FreeTTS includes a number of unit and regression tests.
The unit tests verify that critical routines are working properly. The regression tests verify that the output of FreeTTS matches what is expected. The prerequisites for testing FreeTTS are as follows:.
To run the regression tests, merely type the following in a command prompt situated at the FreeTTS tests directory:. FreeTTS includes a number of demos.
NOTE : The binaries for the demos exist as jar files in the bin directory of the binary distribution. If you only wish to run the demos, follow only the 'Running' instructions for each demo. Note also that the demonstration applications also use a jar Manifest that uses the 'Class-Path' attribute. This program is started by running the following command:. With this, you can record your own voice using the FestVox tools, and then turn the resulting data into a FreeTTS voice.
It's not trivial, and it requires using Festival and FestVox. The results are summarized below:. However, the ability to create your own voices doesn't explain why the current voices sound so bad. FreeTTS uses the same algorithms and voice data from Flite.
Well, first, you are right, it is an 8KHz diphone voice from the last millenium, and that was actually deliberate. As we developed flite we wanted a voice that was stable and that we could directly compare with that very same voice in Festival.
We want to be able take voices built with the FestVox process and compile them for flite, the result should be exactly the same quality though of course trading the size for quality in flite is also an option.
The included voice is just an sample voice that was used in the testing process. We have better voices in Festival and are working on the conversion process to make it both more automatic and more robust and tunable, but we haven't done that yet, so in this first beta release.
This old poor sounding voice is all we have, sorry, we'll provide you with free, high-quality, scalable, configurable, natural sounding voices for flite, in all languages and dialects, with the tools to built new voices efficiently and robustly as soon as we can. Though in the mean time, a few higher quality voices will be released with the next version. As of FreeTTS 1.
As such, you need to use Festival and FestVox to record your data. See our documentation for more detail on how to do this. This is not a trivial task as it requires a lexicon for the language as well as various statistical data about the language.
The audio file format can be. For example, if 'filename' is 'foo. The -dumpMultiAudio option same format as -dumpAudio dumps audio to multiple audio files, one file per utterance.
In this case, if 'filename' is 'foo. Again, the file format is determined by the extension of the filename. If you are writing your own application, you can set the audio player of the FreeTTS Voice to one of the file-based audio players. You probably are trying to run with an older jdk 1. To verify this type:. You should see something like: java version '1. If you see something older that this, such as java version '1.
There are approximately 45 phonemes in the English language. FreeTTS uses a technique called diphone synthesis which uses pairs of phonemes called diphones as an index into the unit database. Not all phoneme combinations occur in the English language. FreeTTS, in order to conserve space, does not include diphone information for diphones that do not naturally occur.
This message indicates that FreeTTS encountered one of these omitted diphones.
