The voice command device (VCD) is a device controlled by human voice. By eliminating the need to use buttons, fast and switches, consumers can easily operate the equipment with their full hands or while performing other tasks. Some of the first examples of VCDs can be found in household appliances with washing machines that allow consumers to operate washing controls via vocal commands and cell phones with voice dialing enabled.
The new VCD is an independent speaker, so they can respond to multiple sounds, regardless of the effect of accents or dialects. They are also capable of responding to multiple commands at once, separating voice messages, and providing appropriate feedback, accurately mimicking natural conversations. They can understand about 50 different commands and retain up to 2 minutes of voice messages. VCDs can be found in computer operating systems, commercial software for computers, cell phones, cars, call centers, and internet search engines like Google.
In 2007, a CNN business article reported that voice commands are a multibillion-dollar industry and that companies like Google and Apple are trying to make speech recognition features. It has been years since the article was published, and since then the world has witnessed various voice command devices. In addition, Google created a speech recognition engine called Pico TTS and Apple has released Siri. Voice command devices are becoming more widely available, and innovative ways to use human voice are always created. For example, Business Week shows that future remote controls will become human voice. Currently, Xbox Live allows such features and Jobs hinted at such features on the new Apple TV.

Product voice command software
Both Apple Mac and Windows PCs provide speech recognition features for their latest operating system.
Microsoft Windows
Two Microsoft operating systems, Windows 7 and Windows Vista, provide speech recognition capabilities. Microsoft integrates voice commands into their operating systems to provide mechanisms for people who want to limit their mouse and keyboard usage, but still want to maintain or improve their overall productivity.
Windows Vista
With Windows Vista sound control, users can dictate documents and emails in the main application, start and switch between applications, control the operating system, format documents, save documents, edit files, correct errors efficiently, and fill out forms on the Web. Speech recognition software learns automatically every time a user uses it, and speech recognition is available in English (US), English (English), German (German), French (French), Spanish (Spanish), Japanese, Chinese (Traditional) and Chinese (Simplified). In addition, the software comes with interactive tutorials, which can be used to train users and voice recognition engines.
Windows 7
In addition to all the features provided in Windows Vista, Windows 7 provides a wizard for setting up microphones and tutorials on how to use the feature.
Mac OS X
All Mac OS X computers have been pre-installed with voice recognition software. The software is user-free, and allows users to, "navigate menus and enter keyboard shortcuts, say name checkboxes, radio button names, list items, and button names; and open, close, control, and switch between apps." However, the Apple website recommends users buy a commercial product called Dictate.
Commercial products
If users are not satisfied with the built-in speech recognition software or the user does not have speech recognition software built for their OS, then the user can experiment with commercial products like DragonNaturallySpeaking for Windows PCs, and dictate, the same software name for Mac OS.

Mobile voice commands
Any mobile device running Android OS, Microsoft Windows Phone, iOS 5 or later, or Blackberry OS provides voice command capability. In addition to speech recognition software built for each mobile operating system, users can download third-party voice commands from any operating system app store: Apple App store, Google Play, Windows Phone Marketplace (originally Windows Marketplace for Mobile), or BlackBerry App World.
Android OS
Google has developed an open source operating system called Android, which allows users to perform voice commands such as: send text messages, listen to music, get directions, contact businesses, call contacts, send emails, view maps, go to websites, write notes , and search Google. Voice recognition software is available for all devices since Android 2.2 "Froyo", but the settings must be set to English. Google allows users to change the language, and the user is prompted when he first uses the voice recognition feature if he wants his voice data attached to their Google account. If a user decides to opt in to this service, this allows Google to train the software to user voice.
Google introduced Google Assistant with Android 7.0 "Nougat". This is much more advanced than the older version.
Amazon.com has an Echo that uses a special version of Android from Amazon to provide a sound interface.
Microsoft Windows
Windows Phone is a Microsoft mobile device operating system. In Windows Phone 7.5, the greeting app is an independent user and can be used to: call someone from your contact list, dial any phone number, redial the last number, send text messages, call your voice mail, open apps, read appointments, request phone status, and search on the web. In addition, speech can also be used during a phone call, and the following actions are possible during a phone call: dial the number, switch on the speakerphone, or call someone, who is holding the current call.
Windows 10 introduces Cortana, a sound control system that replaces the voice control previously used on Windows phones.
iOS
Apple added Voice Control to the iOS device family as a new iPhone OS 3 feature. IPhone 4S, iPad 3, iPad Mini 1G, iPad Air, 1G iPad Pro, 5G and newer iPod Touch, all come with a more sophisticated voice assistant called Siri. Voice Control can still be enabled through the newer Device settings menu. Siri is an independent user-built built-in voice recognition feature that allows users to issue voice commands. With the help of Siri, the user can issue commands like, send text messages, check the weather, set reminders, find information, schedule meetings, send emails, find contacts, set alarms, get directions, track your stock, set timers, voice command sample. In addition, Siri works with Bluetooth and wired headphones.
Speech recognition in car
As car technology improves, more features will be added to the car and this feature will most likely distract the driver. Voice commands for cars, according to CNET, should allow drivers to issue commands and not be disturbed. CNET states that Nuance suggested that in the future they will make software that resembles Siri, but for cars. Most voice recognition software on the market today only has about 50 to 60 voice commands, but Ford Sync has 10,000. However, CNET suggests that even 10,000 voice commands are not enough considering the complexities and tasks one might want users to make while driving. Voice commands for cars differ from voice commands for cell phones and computers because drivers can use this feature to search for nearby restaurants, search for gas, driving directions, road conditions, and nearby hotel locations. Currently, technology allows drivers to issue voice commands on both portable GPS such as Garmin and car manufacturer navigation systems.
