JSRU transcription system
In our research, we employ a machine readable transcription system instead of the standard IPA symbols which cannot be easily understood by computers. The JSRU (Joint Speech Research Unit) alphabet is a system developed for text-to-speech synthesis.
- The two main categories of sounds are consonants and vowels - go to the chart of the IPA sounds to find out more.
- Translation table of JSRU and SAMPA (another machine readable alphabet).
