Many new improvements over earlier models of the phonetic typewriter have resulted from developments which provide means for reducing the number of different displays obtained for the same syllable without unduly increasing the complexity of the machine. In terms of the ultimate machine which should provide means for handling 1000 to 2000 syllables, model III with a maximum capacity of about 100 syllables is still a rudimentary phonetic typewriter. However, the model III provides a complete system from the sounds of speech input to the typed‐page output which is of great value in future research in speech analysis. Specifically, the subjects considered in this paper are as follows: form of the typed presentation, construction, circuits, syllable memory, typing console, spelling memory, choice of vocabulary, procedure for setting up the memory, and codes obtained.
