"...being predictive, being right about the future, is not the point of any given story or novel. The point is about exploring as wide a range of possibilities as possible."
- Peter Watts

Phonographic Locks  
  Doors that open using voice recognition.  

This is a very early description of voice recognition, the first I know of for opening doors.

“Wait until I open the door,” she cried. And then, slowly and distinctly she pronounced the words.
“Open sesame!”
At the sound of her voice, a door in the roof noiselessly opened, and the arm-chairs on which they sat automatically continued their journey.
“Was it the sound of your voice that opened that door?” asked Silas, puzzled.
‘Why, certainly,” replied the young lady. “Almost all our locks are phonographic. We first make the record by speaking into the phonograph, and after that the lock will only open when the same voice repeats the same words, for unless the needle travels in the same groove, the electrical contact is not made, and the door will not open.”
“But how do you manage when several persons are to use the same lock?”
“Each person makes his own phonogram, and the lock will then open to any one of a dozen different voices, each repeating its own special words. When strangers are expected we use a broader needle in making the records. Then the lock will open for anyone who pronounces the given words. Or else we speak through a special horn that changes the voice, so that the lock is not set for an individual voice.”
“But doesn’t your own voice change somewhat at times?”
“Yes indeed. Once I came home so hoarse that my voice wouldn’t work the lock. In another case I had an attack of malaria and was shivering so hard I couldn’t articulate the words. In both cases I had to hire a room downstairs until my family returned.
