But the longer Bell toiled at his musical telegraph, the more he dreamed of replacing the telegraph and its cumbrous sign-language by a new machine that would carry, not dots and dashes, but the human voice. "If I can make a deaf- mute talk," he said, "I can make iron talk." For months he wavered between the two ideas.
But Bell worked from the standpoint of the human voice. He cross-fertilized the two sciences of acoustics and electricity.
He stopped to listen, and, as one of the bystanders afterwards said, no one could forget the look of awe that came into his face as he heard that iron disc talking with a human voice. "This," said he, "comes nearer to overthrowing the doctrine of the conservation of energy than anything I ever saw."
She concluded that she must have mistaken some other sound for that of the

Nor, on bursting into the room without demanding a parley, was their astonishment lessened by the discovery that these romantic sounds certainly proceeded from the throat of some man up the chimney, of whom nothing was visible but a pair of legs, which were dangling above the grate; apparently feeling, with extreme anxiety, for the top bar whereon to effect a landing.
And then, amid the clangour of the machinery, came a drifting suspicion of

The murmur soon became more distinct; it now seemed like a distant concert of
human voices accompanied by brass instruments.
But the
human voice at the end of the phone at a time of need is still important, and so we too make every effort to ensure that the right level of communication and interaction is available.
The researchers presented 22 short
human voice sounds (600 milliseconds) that were neutral utterances or expressed either anger or joy to a small group of people while an electroencephalogram (EEG) -- diagnostic test -- measured electrical activity in the brain down to the millisecond.
