Lojban Speech Synthesis
While the Open Source project supports only English with upcoming IPA support. A Lojban voice can be trained by replacing the ARPAbet dictionary with Lojban equivalent pronunciations. The voice of la selpa'i was synthesized using Lojban Corpus Readings as audio sources. The English ARPABet dictionaries have to be disabled for it to work properly.

The Open Source eSpeak supports Lojban.
Select the "lojban (jbo)" voice.
Command Line Version
- espeak-ng -v jbo
You can then type any Lojban text and press return for it to be read out-loud. Don't press any arrow keys when entering text, as that will cause problems - backspace works fine.
Type in 'jbo' when installing the languages
http://members.home.nl/w.dijkhuis/lojban/z0300_txt2speech_01.htm has some more TTS examples.
There is also lojban_diphone_speech_synthesizer which uses Praat, but a lot of its links are dead now.
