IBM Introduces Speech Recognition Technology Operating over Telephone Lines

By 1971 IBM’s first operational application of speech recognition enabled customer engineers servicing equipment to “talk” to and receive “spoken” answers from a computer that could recognize about 5,000 words. "The Automatic Call Identification system enabled engineers anywhere in the US to talk to and receive “spoken” answers from a computer in Raleigh, NC. It was IBM’s first speech recognition system to operate over telephone lines and respond to a range of different voices and accents" (https://www.ibm.com/ibm/history/ibm100/us/en/icons/speechreco/, accessed 9-2020)
