Spoken Binary Defined  
Try this system with other numbers and different representative sounds. Speaking numbers in English (and many other languages) involves the use of "scale" words,
such as "ten", "hundred" and "thousand", to represent powers of ten.
Numbers spoken before a larger scale word are multiplied and numbers spoken after a larger scale
word are added. So "ten thousand hundred" is Spoken binary uses base two instead of base ten. Scales can be spoken as words. In the table below the words "duo" and "quad" are used to represent scales 2^{1} and 2^{2}. Also illustrated is the used of individuals sounds for scales. The scales 2^{0}, 2^{1} and 2^{2} are represented by the individual sounds [i] ("ee"), [u] ("oo") and [s]. Spoken binary with scales as words or sounds.
Hexadecimal ScalesNo representation of scale 2^{3} was needed since 2*4 can be spoken and equals 2^{3}. In order to avoid repeating scale representations, a representation for 2^{4} is required, and in general 2^{2n} for positive integers n. As the base of hexadecimal is 2^{4}, the representations of "subhex" scales (below sixteen) can be viewed alternatively as representaions of hexamdecimal digits, and binary scales 2^{2n} can be equivalently considered hexadecimal scales 4^{2(n1)}. A challenge of representing scales with individual sounds, is maintaining pronouncability and intelligibility with an increasing number of distinct scales involved. One strategy that works well is to only use consonants for hexadecimal scales and introduce a "null" vowel such as "a". The null vowel can be suffixed to hexadecimal consontants to aid intelligibility and can also be used in isolation to represent zero. Numerically, the "null" symbol represents nothing and is ignored when evaluating a spoken numbers numerical value. For questions, suggestions and errors, email castedo@castedo.com.
