Voice control can make the lights in the corridor light for a period of time, which can save energy; Say the name you want to dial into your mobile phone, and it will automatically connect to the corresponding phone number. Nowadays, people are more and more familiar with voice control technology. Using voice instead of body movements has brought many benefits and conveniences to people. Therefore, more and more voice control devices are widely used in people's lives.
Speech control technology is realized by simulating the principles of human auditory system and understanding system. General voice-activated computer equipment has to undergo a long period of "training" before application. This "training" process is a bit like teaching babies to listen and speak. First of all, we should tell the voice-controlled computer equipment what we know, such as how to say a word correctly. When the computer "learns" these words, it will decompose them into initials and finals in Chinese characters or pinyin to learn them bit by bit. This "training" or "learning" process is time-consuming. Of course, the longer the "learning" time, the smarter the voice control device will be.
Because everyone's voice is very different, so the voice can be used as one of the basis of safety certification. Others can imitate your signature, guess your password and even leave your fingerprints, but it's a bit too difficult to imitate your voice. A smart building in America uses speech recognition. When you arrive at the gate of the company, you must pass the security check. The electronic voice-activated doorman will say "good morning!" You should also answer "Hello!" Or "Good morning!" Polite expressions like that. At this time, the electronic doorman can tell whether you are a company employee by your voice. If it is confirmed, it will open the door for you. If not, the electronic doorman will politely "shut you out".
If you have poor eyesight or difficulty walking, voice control equipment can also help you. For example, you can control washing machines, televisions, computers and other equipment by talking. Let them perform simple tasks, such as opening and closing. Computers equipped with voice control devices can also read newly received emails for you and tell you the latest news.
Philips recently developed a new type of audio equipment. If you want to listen to music, you don't need to go to the stereo to find a button or a remote control. Even if you are in the kitchen, just shout "start playing music" and the stereo in the living room will turn on automatically. Then say the name of the song, and the stereo will find the song to play automatically in a few seconds. What's even more amazing is that if you can't remember the title of the song, just hum the melody of a few songs, and the stereo can tell which song it is, and then play it to you.
After "learning", of course, voice control devices can also be used to teach adults and children to learn languages. For example, if you don't know how to pronounce the sound' wo', the voice control device that has learned this sound can play the moving images of lips and tongue synchronously by pronouncing this sound, so that you can practice it repeatedly until the pronunciation is accurate. Don't worry even if you have hearing problems, because you can imitate and practice by observing the movements of your lips and tongue.
Future voice control devices can also become close friends and assistants of people. When you are upset, it can chat with you to relieve boredom; When you are sick, I can tell you what disease you have and what medicine you should take. When you are on the road, it can guide you and escort you.
However, there are still some problems to be solved in voice control equipment. Now "well-trained" voice control equipment can only understand what we teach. If we don't teach it, it will never "listen" to it. In addition, you may not understand it when the road is noisy or the speaker has a strong accent. At present, there are still many places where people's hearing and understanding systems have not been fully studied, so there is still a lot of room for development of voice control technology.
