Abstract: This invention concerns a system of communication including a tactile device for single-handed input of phonetic information and a corresponding tactile device for output of that information onto a single hand. The phonetic information input using the tactile input device can be output as synthesized speech, and the tactile output device can receive phonetic information obtained from a speech recognition engine. Thus the input device acts as a “talking hand”, and the output device acts as a “listening hand”. The phonemic information is suitable for tactile or speech output, either directly or indirectly, locally or remotely, via a transmission system such as a telephone network. The system involves a scheme in which the fingers are used for consonants and the thumb for vowels, with fingers and thumb used together for voiced consonants.
