Symbol system developed for deaf people education, in which each speech sound is represented by a separate finger sign. The finger alphabet cannot be confused with sign language. Sign language is a non-verbal system with own conventions and meanings. The point of departure of the finger alphabet is the spoken language. The finger alphabet can thus only be used if one masters the conventions of the spoken language and if one can spell. Because of this, and also because the system of finger spelling works rather slowly (max. 60 words per minute), the finger alphabet is mainly used as a support of normal sign language.
