O MOM AND DAD

A man from AT&T has pulled Ray Bradbury’s lucky ping-pong ballout of a barrel. The loudmouth in glasses just won a free long-distancecall to anywhere in the United States but Queens. He’ll be speakingwith his parents in Los Angeles and three hundred strangers will beallowed to eavesdrop—a boast of reach and clarity, courtesy of thephone company. This deprivation of privacy doesn’t concern Bradbury,the know-it-all at eighteen.

AT&T’s complimentary scheme was a huge draw at the World’s Fairin Flushing Meadows, New York. Free long distance was good in Julyof 1939. Free was good for Ray Bradbury, who had hot water andketchup for lunch, called it tomato soup and didn’t care because he’dmet Isaac Asimov and a man who drew giant ants.

That summer, the World’s Fair was an optimistic golly between theGreat Depression and World War II. Apprehension was confused withgiddiness, as Hitler had already invaded Czechoslovakia before theCzechoslovakian pavilion was even completed. By the Fair’s secondseason, France had fallen and the queue into the Perisphere, snap-brimmed and scarved, could’ve been boarding the next planet out ofhere. When the Fair closed, in October 1940, the World of Tomorrowwas dismantled and the scrap metal skipped the modern kitchen tobe recycled for the war machine.

This future would be quickly assessed in “Galactic Report Card,” astory in which aliens went around grading the planets. Written byBradbury’s friend Forrest J. Ackerman, the story is approximatelyone letter in length—Earth is handed a decisive “F.” Ackermanshared Bradbury’s weakness for abominable puns and paid for thebus trip from Los Angeles so the author of “Don’t Get Technatal”could join him at the first annual World Science Fiction Conventionin Manhattan. Afterward they would go to Flushing to see how theFair sized up against their full-blown imaginations, less interestedin the canary that tested refrigerants at the GM building than Dalí’stopless squid ladies.

The future would be like this: a drunk passed out in a simulated frontyard. There were miniature freeways and manmade lightning. Modelhomes and model cities. Artifice was in. At the Firestone Farm, men inheadsets triggered barnyard noises. Oinks, ribbits, lows, clucks andgrunts. Yawps, quacks, chirps and peeps. Chimp hysterics. Birdtalk.The real animals weren’t really into it. The real monkeys got sick andthe real ducks ate most of the real frogs.

Setting new standards for nerding out, Ackerman wore a space toga andspoke Esperanto. He told people he was a time traveler from the future,a future where he would star in Nudist Colony of the Dead, coin theterm “Sci Fi,” and become L. Ron Hubbard’s literary agent. Bradbury,the street-corner paperboy, wandered the paved swamps of Queenshyping Fritz Lang’s Metropolis, a film in which Germany out-futured

the Fair in just under two hours, and without sound. Unlike Metropolis,the Fair offered no robot beauty. Just Elektro, an eight-foot clunker thatcould smoke cigarettes and hiccup. Canned and recorded at 78 rpm,his human voice betrayed the novelty.

“The robots weren’t exciting,” Bradbury told me over the phone fromLos Angeles. “But the architecture was. I never much cared for robots.The robot was an idiot.”

AS IF TO SAY

You flower of untimeliness, you rabbit of dark rooms! Your voice isour hereafter, and it has crowded out heaven!

— Arnolt Bronnen, addressing the telephone, 1926

My call to Ray Bradbury lasted twenty-seven minutes, cost about $10and informed me that the eighty-five-year-old author would alwaystake the stegosaurus over the robot. We talked about synthetic micethat cleaned houses and laughed at Albert Brock, a man driven insaneby his telephone. “The phone drained your personality away untilwhat slipped through at the other end was some cold fish of a voice,all steel, copper, plastic, no warmth, no reality.” That’s Brock’s voicein Bradbury’s words, from a 1953 story called “The Murderer.” To Mr.Brock, get the phone meant feeding it to the InSinkErator. “It wasn’tthe technology,” says Bradbury. “It was the voices. Albert Brock wasanti-interference!”

Though the phone often gets the blame, people in the gaslight eraweren’t accustomed to receiving speech from inanimate objects,unless it was Edison’s phonograph (billed as a talking machine itself),but certainly not a tube that originated from a vibrating pig bladder andplatinum. In 1876, the pinhole gulf between voice and voice box wouldexpand, infamously, when Brazil’s Emperor Dom Pedro received hisfirst phone call and, in a confused burst, exclaimed: “My God! It talks!”

Always in the market for a confused burst, Bell Labs would nameits articulate keyboard “Pedro” when it was introduced at the World’sFair in 1939, in both New York and San Francisco. (“Facsimile

Versus the Code Philosophy in the Transmission of Speech” costtoo much oxygen.) Officially, Pedro was a Voice Operating DEmonstratoR,or Voder, a keyboard that simulated speech while alienating the voicefrom its mechanism, the human body. The Voder was a noveltyoutgrowth of the vocoder, then being investigated for speech privacysystems, described by the Hopewell Herald as “Goldarnedest…the Versatile Daddy.”

Played by telephone operators, the Voder’s chubby keys provided thephonetic transcription of consonants and vowels while foot pedals dictatedthe tonal shading and pitch. Speech was sourced from two basicoscillations: buzz and hiss. The buzz—which originated in a “relaxationoscillator”—accounted for voiced sounds (vowels and vibrations). Thehiss derived from an electron free-for-all in a vacuum tube and wasresponsible for unvoiced sounds, breath flushed from the lungs throughthe teeth, lips and tongue. The air was in the electricity.

In an attempt to put a face to the voice, AT&T commissioned a paintingfor its awkward star, somewhere between Art Deco and Dilbert-headed,with a receding Ludwiggian brow offset by golden squiggles of phonecord (hair) and a loudspeaker stuffed in its astonished rabbit hole.

The media response to the Voder ranged from droll (“the talking wall”)to freak-show hysteria (“The Terrifying Metal Man”). Its most humanquality wasn’t so much the ability to talk and sing but an instinctfor corny banter, thus making it a huge draw at the Fair. The machinecould answer simple questions and chat up the Firestone Farm. Itcould drawl. It could twang. It could page lost husbands. It could say“non-intercommunicability.” It could mimic a woodpecker headbuttinga telephone pole. It tried to put a baby to sleep but couldn’t say “lullaby.”(Double l’s were difficult and hell was out of the question.) Whenpresented with larger freight like “potentiometer,” the Voder stumbledgroggily, like a darted bear. When one inebriated customer dared themachine to say “Aberystwyth,” the Voder seemed to mock the word,testing the bounds of elasticity. A visiting class of blind schoolchildrenwas utterly charmed.

According to Bell Labs, the Voder required a

“peculiar combination of particular talents

which are not too common.” Telephone

operators trained a year to make the machine

coherent and sometimes wore translucent

sleeve protectors called “Cuff-Ettes.” (Courtesy

For all its gimmickry, the Voder was difficult to manage, a male personaplayed by women, whose voices were considered too high-pitched to berecognized by the vocoder itself. Only trained telephone operators, thedisembodied voices of the switchboard, had the hand-ear coordinationto give the machine the social skills to work the room, a sort of remedialSpeak & Spell. A simple phrase (“I am not wearing a bear suit”) calledfor deft key and foot-pedal movements. Intelligibility proved to be achallenge when machines weren’t expected to speak in the first place,much less respond in Latin.

During its developmental stages at Bell Labs, the Voder would oftenclub its syllables with an involuntary whoomp and zizz. At one point,a simple “yes” was transmuted into the word “peanuts,” no less muddledthan Charlie Brown’s PTA.

“It’s a wonder that the Voder could talk at all,” wrote its inventor,Homer Dudley, in the Bell Technical Journal. Homer’s daughter,twelve-year-old Jean, was not impressed. “Oh-ah-eh,” she says, in thekey of blah-blah, now living in upstate New York. “The Voder wasboring.” Jean and her younger sister Pat had come to the World’s Fairto play in the Perisphere and eat the free cheese from Holland. “Iwanted the Voder to sound like a real person. I enjoyed it the first tentimes but then it got tedious. What impressed me was my father gotus in for free.”

FOR ILIAD D’OH

Open the door, Homer. — Bob Dylan

Homie, please open the door!— Marge Simpson

Homer W. Dudley invented the vocoder when he realized his mouth wasa radio station while flat on his back in a Manhattan hospital bed, eyeson the ceiling, a goldfish as his witness. It was October 1928, a yearbefore the stock market fell on its head. The end of the Era of WonderfulNonsense. Germany had electromagnetic tape. Bell Labs, the researchdivision of AT&T, had already broadcast Herbert Hoover’s forehead ona televised signal. They had also sent a fax, invented negative feedback,and coined Quality Assurance—the nebulous back-pat of automatedspeech recognition menus, less assurance than a promise that someonein a building without windows was eavesdropping.

The radio inside Dudley’s mouth was no whim ofdental conductivity, falling for that old hygienist’stale about catching baseball games in cavityfillings. He was considering the carrier nature ofspeech and the frequency of muscular vibrationsproduced by the vocal tract. Ralph LaRueMiller, who joined Dudley in the Bell LabsAcoustics Research Department in 1929, remem-bers the story. “Homer was in the hospital,gazing at the ceiling and fiddling around with hismouth—that’s when the real dawn came. Hesuddenly realized, well, I don’t know if it wassudden or not, but he realized that your mouthreally is a miniature radio station. The vocalcords are your transmitter and the shape of yourmouth is the thing that shapes the wave. Herealized that the motions of your mouth andtongue were very slow, much slower than thefrequencies that came out.”

Dudley, a thirty-two-year-old speech engineer from the ShenandoahValley, just wanted to transmit speech underwater. With new improvementson the transatlantic cable—rumored to have suffered a Kraken attackduring its construction on the ocean floor in 1866—it was then possibleto cram more telephone conversations within a given bandwidth.Dudley thought the articulatory motions of the tongue, lips and mouthcould be electronically mimicked, being far more sluggish and lower infrequency than the speech sounds they produced. Thus a “specification”of speech—its spectral information—could be transmitted overtransatlantic links, allowing ten phone channels to occupy the spaceof one. Though Dudley imagined his robot in every American home,the reduced bandwidth was canceled by the cost and the garble, aswell as space hogged by the machine itself—as if every Americanhome could have its own vocoder room.

Homer Dudley explained the vocoder to his children in terms ofbreakfast: scrambling eggs and then basically re-chickening them. “Thevocoder took the sound and breath patterns of Pedro’s technology,”his daughter Jean told me by phone. “It took a coded message, broke itup like scrambled eggs and reassembled it in a different order andsent it. The vocoder on the receiving end broke them up again andreassembled [the message] in the right order, like acrostics or something.”

Bell Labs described the vocoder in terms of analysis and synthesis. Itdivided voice frequencies into ten bands at 300 hertz each, one-tenthof the bandwidth required for phone conversations at the time. Eachfilter measured the voltage required for its speech frequency range.This information was low-pass filtered at 25 hertz and transmitted tothe receiving end, which determined a fundamental pitch frequency(in the eleventh channel) and an unvoiced noise signal to synthesizethe voice. Bell Labs favored synthesize over reconstruct because thelatter implied flawless duplication.

“The first telephone cable in 1956 had fourteen telephone channels,”said Manfred Schroeder, hired by Bell Labs in 1954. “With the vocoderwe could’ve made this into four hundred. That would’ve been wonderful.Between England and the United States, just fourteen channels wasn’tenough. By the time we were ready, they had their satellites up withhundreds and thousands of channels. And by the time we had thingsthat would’ve augmented the satellites, they had fiber-optic cablesrunning through the Atlantic. So there was never much technicalinterest in what we did. Bandwidth was no longer a concern—thisthing we had worked on for all our lives. But then came the Internetand cell phones. Now you are using compressed speech. That is LinearPrediction vocoder technology.”

Linear Predictive Coding originated as a computer model of the vocaltract shape. “Compression was the starting point of what you see in cellphones,” says Bishnu Atal, an innovator of LPC who worked closelywith Dudley at Bell Labs in the Fifties. “The idea [of compression]was dormant until 1980, when we started applying it to cell phones.The vocoder was a dirty narrow word because, after thirty years, itstill couldn’t carry a telephone conversation. But now it’s all aboutcompression—Dudley’s original idea.”

SHOE BENCH

Homer Dudley, a physicist who kept bees, joined the Bell Labs AcousticsResearch Department in 1921, the year the word robot was first placedin circulation by the Czechoslovakian writer Karel Capek, in his playR.U.R. Ralph Miller remembers Bell Labs being somewhat insulatedfrom the Depression. “One of the things about Bell Labs in those days[was] if you had ideas about something that might help the telephone,they let you go off in the corner and work on it. When Homer got out ofthe hospital he started making proposals.”

At Bell Labs, located at 463 West Street in Manhattan, the tongue wasreferred to as a lumped impedance structure and the letter k was aminiature explosive impulse. There, human speech was generated fromthe most inhuman of noises. Donkeys talked, storms howled sentences,and church bells scolded, “Stop! Stop! Don’t do that!” The witches ofMacbeth cackled “deeper than the deepest bass.” The roar of the surf,Niagara Falls, submarine engines, tap dancing, birds, disturbedleaves—all had something to say. The vocoder had an anthropomorphicball, often on reality’s dime. Memos typed on tracing paper addressedproblems with “buzz-saw quality” and “jars of severity.” The term “shoebench” was subjected to rigorous testing and spectral analysis, andultimately recorded to vinyl. Other times, a simple “shh” would do, asif engineers were shushing the machine. Wrote Dudley in 1944: “Onescarcely realizes how many sounds are of a random nature until he startsgiving voice to them.”

keyboard invented in 1835 by Joseph Faber, a

hypochondriac land-surveyor for the emperor

of Vienna. Controlled by sixteen keys and a

foot pedal for its lung bellows, Faber’s “verse-

grinding machine” was well received in London,

such that the press suggested replacing the

House of Commons with Automatons. The

Euphonia would later appear in the Fred Perkins

story “Man-ufactory,” published in 1873. Perkins’

In 1933, Homer Dudley was promoted to head of the Bell Labs AcousticsResearch Department. Not being a people person, he suffered a nervousbreakdown and was diagnosed with acute colitis, an inflammationof the colon that triggered a near-fatal effluxion. So the beekeeperwho tore speech to pieces was back in the hospital, staring at theceiling and thinking about the vocoder, waiting for his blood to coagulate,while the goldfish twitched about in its bowl without a memoryto occupy itself.

MY TEACHER’S SCREWY

According to a lab notebook entry from 1929, Dudley’s vocoder wasinfluenced by the work of Karl Willy Wagner, a German pioneer inautomated speech research. Wagner developed a vowel synthesizer in1936, a year after Dudley filed his signal transmission patent forthe vocoder. In 1936, the vocoder made its public debut at HarvardUniversity’s Tercentenary Celebration in Cambridge, Massachusetts.Standing before his seven-foot tower of dials, Homer Dudley conductedparalinguistic cues, exaggerating the pitch and jumping betweenEnglish and Swedish, often landing on the last syllable with both feet.He called it “The Greta Garble Effect,” a joke on coherence. He thendropped into a power monk drone, as if trying to inhale the audiencegasp. He harmonized with his “electrical doubles,” did the Trans-HomerExpress with a steam engine, and rasped an Exorcist version of SuzySeashells. There were vocoder recordings of Protestant hymns, forlornballads, and an ad for Silly Willie Toothpaste (“You can use it to polishyour car!”). For “Barnacle Bill,” the pitch bottomed out like an ogresuffering from moat throat. “Happy Birthday” sounded like Mr. Bill indrag, pitched so high that the Hopewell Herald would later write that“a colortura soprano canary would have burst its vocal plumbing.”

At another vocoder demonstration at the Franklin Institute in Philadelphia,Dudley had a power line humming as “the voice of electricity,” lightinghouses and claiming to be power itself, before wartime blackoutsrevived the candle. Thirty-six years later, Düsseldorf electronic groupKraftwerk—named after a power plant—would cover this plug tunein German, through a vocoder.

In Robert Heinlein’s 1951 book, BetweenPlanets, the Voder appears strapped to thechest of a seven-eyed dragon from Venus.(Pictured above with the glassed-in tricyclebug coffin.) The dragon pounds the keyboardwith his tendrils, as if to clear his throat, andthus discovers his favorite word: Shucks.

In 1939, while the Voder played the ham at the World’s Fair, ascreenwriter named Gilbert Wright discovered his electric razorcould speak by essentially putting his Adam’s apple on vibrate. Thisshaving epiphany would be patented as the Sonovox, a device thatwould give machines—and products—a voice. When held to thethroat, the Sonovox’s vibrating speaker cones could channel phonographrecordings of airplanes, engines and vacuum cleaners from the studioconsole, allowing humans to pantomime noise into speech. Ideal forradio spots and jingles—and ultimately counting down the hits withCasey Kasem on American Top 40—the Sonovox’s major debut wouldbe in a wheezing steam engine in Dumbo.

+ + +

At the Acoustical Society of America in Manhattan, Homer Dudleywould hype the vocoder’s commercial appeal for cartoon voices,something beyond the helium quacks of Disney. In the summer of 1939,while the Sonovox appeared in Time magazine, Dudley visited MGMStudios in Hollywood, offering the vocoder as “a scientific aid to moviestars,” claiming his invention could revive silent stars canned by theadvent of talkies. Actors could essentially swap larynges, enunciatingthe pitch provided by a “surrogate throat.” With its overdubbingpotential, the vocoder could airbrush defective voices and create theillusion that actors could sing. This pitch-doctoring anticipated theAuto-Tune software in pop music today. Gee-whizzing in the Los AngelesTimes, Philip Scheuer claimed the vocoder could transform any voiceinto “The Voice True”: “a squeak into an oratorio, a bumpkin intoBarrymore, a hash-slinger into Lily Pons.”

At the Hollywood demo, Dudley’s associate Charles Vadersen sang“How Dry I Am” through the vocoder, multiplexing his voice, and thenbecame an airplane taking a nosedive. Dudley then “fluttered” the pitchcontrols and triggered a domestic squabble with himself, spanning threegenerations. Father scolds daughter (“Nevermind that flip talk!”),daughter back-talks (“My teacher’s screwy, Daddy!”), Grandpa Gizzardwarbles in, and mother takes a hit of scotch. Said the LA Times,“Anything so wondrous, so stupendous, so complicated and so confusingmust find a place in movie-making.”

In his 1910 book, The History of the Telephone,Herbert Casson describes the telephone asa “living, conscious being, half human andhalf machine.” In addition to picking uptransmissions from the deceased, the phonealso acquired “noises!…Spluttering and bubbling,jerking and rasping, whistling and screaming.There were the rustling of leaves, the croakingof frogs, the hissing of steam, and the flappingof bird wings…scraps of talk from otherphones, and curious little squeals that wereunlike any known sound.”

WORD’S FEAR

Hollywood would have to wait. All things wondrous, stupendous,complicated and confusing must report to the army first. Though theWorld’s Fair could make claims on the future, the military officiallyhad dibs on tomorrow. Long before the vocoder played the voice of amissile-happy Cold War supercomputer in 1970’s Colossus: The ForbinProject, it held an underground desk job, scrambling the phone calls ofthe army’s triple-chinned brass. Patriotic orders to fill, eggs to scramble.Things to come, things to do.

Writing in the New Yorker, Martian-mongerer H.G. Wells predicted thatthe World’s Fair would introduce teleconferencing, a snooze buttonof a prophecy but less dooming than the atomic conflict he foresaw inhis 1914 book The World Set Free. Ray Bradbury, the loud blonddreamer, was terrified. No topless squid lady could distract him from theprospect of the sky above whistling straight to hell.

Those at the Fair who eavesdropped on Bradbury’s free call to LosAngeles probably just admired the clarity, marveling at voices shootingacross time zones. Perhaps they mistook his modulated quaver forhomesickness, not the fear that he’d never again see his parents. I loveyou. I miss you. I’m broke.
