The Digital Voice Exchange
The Wang DVX was one of the first integrated switchboard and voicemail systems. In the United Kingdom it was selected for the DTI Office Automation Pilot schemes at the National Coal Board in about 1980.
Lawrence E. Bergeron was instrumental in managing the Voice Engineering Department at Wang Labs. He promoted the purchase of a VAX-11/780 for 'real-time' signal processing research and created the Peripheral Signal Processor board (PSP). The PSP was placed into 16 racks to handle 128 phone lines for the DVX (Digital Voice Exchange).
Voice prompts were created by a hired voice specialist to give a melodic presentation for the DVX. To avoid false triggering of touch-tones by the prompts (due to input/output cross talk), notch filters were created to remove the touch tone frequencies from the prompts.
Some of the prompt languages supported were: German, Spanish, French, British English, American English, and Portuguese.
Internal research on speech recognition was carried out and implemented for discrete word recognition but was never released to the field.
At one point there were 50 members of the Voice Engineering Department.

Famous quotes containing the words voice and/or exchange:
““Maman”, said Annaïse, her voice strangely weak. “Here is the water.”
A thin blade of silver came forward in the plain and the peasants ran alongside it, crying and singing.
...
“Oh, Manuel, Manuel, why are you dead?” moaned Délira.
“No”, said Annaïse, and she smiled through her tears, “no, he is not dead”.
She took the old woman’s hand and pressed gently against her belly where new life stirred.”
—Jacques Roumain (1907–1945)
“I can exchange opinion with any neighbouring mind,
I have as healthy flesh and blood as any rhymer’s had,
But O! my Heart could bear no more when the upland caught the wind;
I ran, I ran, from my love’s side because my Heart went mad.”
—William Butler Yeats (1865–1939)
