A voice command device (VCD) is a device controlled by means of the human voice. By removing the need to use buttons, dials and switches, consumers can easily operate appliances with their hands full or while doing other tasks. Some of the first examples of VCDs can be found in home appliances with washing machines that allow consumers to operate washing controls through vocal commands and mobile phones with voice-activated dialing.
Newer VCDs are speaker-independent, so they can respond to multiple voices, regardless of accent or dialectal influences. They are also capable of responding to several commands at once, separating vocal messages, and providing appropriate feedback, accurately imitating a natural conversation. They can understand around 50 different commands and retain up to 2 minutes of vocal messages. VCDs can be found in computer operating systems, commercial software for computers, mobile phones, cars, call centers, and internet search engines such as Google.
In 2007, a CNN business article reported that voice command was over a billion dollar industry and that companies like Google and Apple were trying to create voice recognition features. It has been five years since the article was published, and since then the world has witnessed a variety of voice command devices. In addition, Google created a voice recognition engine called Pico TTS and Apple has released Siri. Voice command devices are becoming more widely available, and innovative ways for using the human voice are always being created. For example, Business Week suggests that the future remote controller is going to be the human voice. Currently Xbox Live allows such features and Jobs hinted at such a feature on the new Apple TV.

Famous quotes containing the words voice, command and/or device:
“If we would enjoy the most intimate society with that in each of us which is without, or above, being spoken to, we must not only be silent, but commonly so far apart bodily that we cannot possibly hear each other’s voice in any case. Referred to this standard, speech is for the convenience of those who are hard of hearing; but there are many fine things which we cannot say if we have to shout.”
—Henry David Thoreau (1817–1862)
“By his command these words are cut:
Cast a cold eye
On life, on death.
Horseman, pass by!”
—William Butler Yeats (1865–1939)
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
