NOTE:Examples on this website involving Klatt synthesis are currently not working. We are aware of the problem and will fix it as soon as we can.
This interface allows you to synthesize non-nasalized monopthongal English vowels using the Klatt synthesizer. It provides control over vowel duration, voice pitch, and the first three formant frequencies. All the other possible control parameters are fixed at (reasonable?) defaults. For a much more general interface to the synthesizer, see the full Klatt Synthesis Interface. If you want a simplified interface to make CV syllables, see the CV Interface.
