Can intelligent speech recognition lead the smart home voice control

When it comes to voice-activated voice recognition technology, we can't help but think of Apple's iphone's siri function. Through this intelligent voice system, users can read text messages, introduce restaurants, ask weather, voice alarms, etc. through siri, siri also supports natural voice input, and can Calling the system's own weather forecast, schedule, search data and other applications, can also continue to learn new voices and intonation, providing a conversational response. Siri's answer to the user's inquiry is not to answer questions. Sometimes it gives people a sense of ingenuity. This is the innovative technology of intelligent voice control.

In the past two decades, speech recognition technology has made significant progress and has begun to move from the laboratory to the market. It is expected that in the next 10 years, speech recognition technology will enter various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, and consumer electronics. Many experts believe that speech recognition technology is one of the ten most important technological development technologies in the field of information technology between 2000 and 2010.

There are five main problems in intelligent speech recognition:

1. Recognition and understanding of natural language. First, the continuous speech must be decomposed into units such as words and phonemes, and secondly, a rule for understanding semantics should be established.

2. The amount of voice information is large. The speech mode is not only different for different speakers, but also different for the same speaker. For example, a speaker's voice information is different when he speaks casually and speaks seriously. The way a person speaks changes over time.

3. The ambiguity of speech. Different words may sound similar when the speaker is speaking. This is common in English and Chinese.

4. The speech characteristics of a single letter or word or word are affected by the context, so that the accent, pitch, volume and pronunciation speed are changed;

5. Environmental noise and interference have a serious impact on speech recognition, resulting in low recognition rate.

The application of speech recognition on mobile terminals is the hottest, and voice dialogue robots, voice assistants, and interactive tools are emerging one after another. Many Internet companies have invested in human resources, material resources and financial resources to carry out research and application in this field. Around us, the most familiar is Apple's siri system, which is a very cool feature, but there are very few users who actually use this voice system.

Although the existence of the voice control system is inherently problematic, the application of this technology in the intelligent industry will cause a wave of turmoil in the industry. However, due to the following characteristics, it cannot be applied to the superior control of each system: the operation is easy to make mistakes; the completeness is low; the recognition rate The error rate is more likely (especially for high precision requirements). But its control features, such as simplicity, ease of use, interactivity, and entertainment, are perfect for smart home applications.

First, as a smart home system based on cloud computing and speech recognition technology, it will provide more operational control methods for existing smart home systems. At present, there are three control methods for smart home systems: panel control, original touch screen, third-party panel control (ipad, smart phone, etc.). For example, the smart home system based on cloud computing and speech recognition technology not only adds an operation mode, but also revolutionizes the smart home field. On the human-machine interface, direct operation with voice does not require the presence of a panel, and cloud computing requires no computing power locally. Therefore, the control terminal can be designed to be convenient to carry around, such as a watch, an earphone, and the like, and a more convenient control terminal form.

Secondly, direct human-machine voice dialogue through voice represents a better user experience. The direct human-machine voice dialogue through voice is the decomposition of the vocabulary of human speech, and the content is converted into computer-readable input, such as buttons, binary codes or character sequences. Thinking is the function of the human brain and a reflection of external reality; language is the tool of realistic thinking, consolidating and conveying the result of thinking, that is, thinking. Language is the element of thinking itself, the element of life representation of thought; language is the tool of thinking and the direct reality of thought. Language is the most convenient and understandable command mode for human beings. Unless the sensor can directly act on the human brain, it is difficult to have a more convenient and quick way.

Again, natural language answers represent the ultimate form of future intelligent products. The natural answer function based on cloud computing combined with the smart home system can open up countless functions and applications, such as simple voice commands for it, "turn on the lights", "pull curtains", etc., and can also use the cloud computing function. The command is even a common language for deep understanding. Such as "Q: The weather is too hot. A: The air conditioner is going to be lower than the comfort temperature. Are you sure you want to lower it?" Another example is "Q: I want a car, I can come in 15 minutes. Smart home automatic dialing And book a car."

Although the smart home system has already introduced voice control into it, and boasted that it will be the mainstream direction in the future, but due to various factors such as the degree of discrimination and environmental interference, the voice system has not really entered. Smart home system, and the so-called trend of leading smart home voice control, is still too early! Only technology upgrades and product updates can really make voice control technology enter the smart home market!
