Speedtalk is an idea for a new language put forth by Robert A. Heinlein in his novella, Gulf. Speedtalk is an entirely logic-based language which does not waste any words or phonetic sounds and is therefore extremely efficient. Heinlein's own description follows:
Speedtalk was a structurally different speech from any the race had ever used...eight hundred and fifty words were sufficient vocabulary to express anything that could be expressed by "normal" human vocabularies, with the aid of a handful of special words -- a hundred odd -- for each special field, such as horse racing or ballistics...Phoneticians had analyzed all human tongues into about a hundred-odd sounds, represented by the letters of a general phonetic alphabet.

On these two propositions Speedtalk was based.

To be sure, the phonetic alphabet was much less in number than the words in Basic English. But the letters representing sound in the phonetic alphabet were each capable of variation several different ways -- length, stress, pitch, rising, falling. The more trained an ear was the larger the number of possible variations, but, without much refinement of accepted phonetic practice, it was possible to establish a one-to-one relationship with Basic English so that one phonetic symbol was equivalent to an entire word in a "normal" language, one Speedtalk word was equal to an entire sentence. The language consequently was learned by letter units rather than by word units -- but each word was spoken and listened to as a single structured gestalt.

But Speedtalk was not "shorthand" Basic English. "Normal" languages, having their roots in days of superstition and ignorance, have in them inherently and unescapably wrong structures of mistaken ideas about the universe. One can think logically in English only by extreme effort, so bad it is as a mental tool. For example, the verb "to be" in English has twenty-one distinct meanings, every single one of which is false-to-fact.

A symbolic structure, invented instead of accepted without question, can be made similar in structure to the real-world to which it refers. The structure of Speedtalk did not contain the hidden errors of English; it was structured as much like the real world as the New Men could make it. For example, it did not contain the unreal distinction between nouns and verbs found in most other languages. The world -- the continuum known to science and including all human activity -- does not contain "noun things" and "verb things"; it contains space-time events and relationships between them. The advantage for achieving truth, or something more nearly like truth, was similar to the advantage of keeping account books in Arabic numerals rather than Roman.

All other languages made scientific, multi-valued logic almost impossible to achieve; in Speedtalk it was as difficult not to be logical. Compare the pellucid Boolean logic with the obscurities of the Aristotelean logic it supplanted.

Paradoxes are verbal, do not exist in the real world -- and Speedtalk did not have such built into it. Who shaves the Spanish Barber? Answer: follow him around and see. In the syntax of Speedtalk the paradox of the Spanish Barber could not even be expressed, save as a self-evident error.

...

An economical language cannot be limited to a thousand words; although almost every idea can be expressed somehow in a short vocabulary, higher orders of abstraction are convenient. For technical words Speedtalk employed an open expansion of sixty of the thousand-odd phonetic letters. They were the letters ordinarily used as numerals; by preceding a number with a letter used for no other purpose, the symbol was designated as having a word value.

New Men numbered to the base sixty -- three times four times five, a convenient, easily factored system, most economical, i.e., the symbol "100" identified the number described in English as thirty-six hundred -- yet permitting quick, in-the-head translation from common notation to Speedtalk figures and vice versa.

By using these figures, each prefaced by the indicator -- a voiceless Welsh or Burmese "1" -- a pool of 215,999 words (one less than the cube of sixty) were available for specialized meaning without using more than four letters including the indicator. Most of them could be pronounced as only one syllable. These had not the stark simplicity of basic Speedtalk; nevertheless words such as "icthyophagous" and "contitutionality" were thus compressed to monosyllables. Such shortcuts can best be appreciated by anyone who has heard a long speech in Cantonese translated into a short speech in English. Yet English is not the most terse of "normal" languages -- and expanded Speedtalk is many times more economical than the briefest of "normal" tongues.

By adding one more letter (sixty to the fourth power) just short of thirteen million words could be added if needed -- and most of them could still be pronounced as one syllable.

...

Human thought was performed, when done efficiently, only in symbols; the notion of "pure" thought, free of abstracted speech symbols, was merely fantasy. The brain was so constructed as to work without symbols only on the animal level; to speak of "reasoning" without symbols was to speak nonsense.

Speedtalk did not merely speed up communication -- by its structures it made thought more logical; by its economy it made thought processes enormously faster, since it takes almost as long to think a word as it does to speak it.

...

Living time is not calendar time; a man's life is the thought that flows through his brain. Any man capable of learning Speedtalk had an association time at least three times as fast as an ordinary man. Speedtalk itself enabled him to manipulate symbols approximately seven times as fast as English symbols could be manipulated. Seven times three is twenty-one; a new man had an effective life time of at least sixteen hundred years, reckoned in flow of ideas.

If you managed to read through all that and understand it, you no doubt see now why Heinlein is considered the grand master of science fiction. His ideas regarding Speedtalk are not only sound, they are intriguing. The way Heinlein puts it, it seems that for the human race to evolve to "the next level", we must invent a more effective, logical, and efficient form of communication -- one much like Speedtalk.
