Another widespread approach is to visually represent the phonemes (sounds) of an oral language, rather than using signs for the words. These systems are sometimes known as "Mouth Hand Systems" (MHS). An early example was developed in Denmark in 1903 by Georg Forchhammer. Others include the Assisted Kinemes Alphabet (Belgium) and a Persian system developed in 1935 by Jabar Baghtcheban—in addition to the most widespread MHS worldwide, Cued Speech. As the entire set of phonemes for an oral language is small (English has 35 to 45, depending on the dialect), an MHS is relatively easy to adapt for other languages.
