How about intelligent voice control system? What are the factors that affect the effectiveness of intelligent voice control systems?

The intelligent voice control system is part of the smart home control system, and it is also part of the intelligent home voice control system. Although many smart home products can be controlled through voice at the current stage, it is often not in the actual operation process. As best wishes, the following editors will share with you the introduction of intelligent voice control systems and the factors that influence the effectiveness of smart home voice control systems.

Smart home voice control system

The application of non-specific human voice recognition technology in smart home systems is studied. The intelligent home voice control system is designed based on the relevant characteristics and latest development trend of the Internet of Things. The system consists of mobile terminal control software and embedded portable voice controller. The embedded portable voice control terminal adopts the system architecture of LD3320+STM32+CC2430 and combines 802.15.4E wireless communication protocol to design. Practice has proved that this voice control system realizes diversified and comprehensive voice control of controllable devices in smart homes.

Smart Home Voice Control System

Looking around the world, smart voices get together and a wave of voice control has become overwhelming. Although faced with some technical bottlenecks such as speech recognition rate and voice collection problems, we believe that integrating technologies into more areas will continue to be an irresistible trend, hampering the accuracy and stability of its applications. The problem is also expected to be solved. For the future development direction of smart homes, the application of voice control technology to smart homes will be one of the new trends in the future market development. We also hope that this situation can be started as soon as possible.

What are the factors that affect the effectiveness of intelligent voice control systems?

Voice Control Smart Home - Distance Issues Are Key

Near-field recognition technology is relatively mature. The voice input function used on mobile phones now belongs to near-field recognition technology. The user must speak within a short distance from the mobile phone, but in a smart home environment, between the user and the smart terminal. The distance has been greatly increased. A necessary condition for users to freely control the smart home with their voice is that the device can accurately identify wherever you are in the living room, and the voice recognition technology must overcome distance obstacles. Currently, indoor voice interactions are affected by multiple complex factors such as background noise, other vocal disturbances, echoes, and reverberation. As a result, the recognition rate is low or even unusable, and it can only be used in relatively quiet and close-range environments.

Voice control smart home - dialect influence recognition

As we all know, China’s voice and language are extensive and profound. Although the country spares no effort in promoting standard Putonghua, the proportion of Chinese who actually master standard Putonghua is still relatively low, and the Chinese accent phenomenon is complicated and may even appear in the same city. Different accent conditions. Therefore, when these people with light or heavy accents are using speech input, if they use the standard Mandarin data to train the model in the usual way, they will have very serious adaptation problems, thus affecting the recognition of speech input. effect.

Voice control smart home - low identification capacity

In addition to improving the recognition accuracy of the user's speech input, the intelligent speech technology also needs to improve the semantic understanding ability. Even world-class audio assistant tools such as Apple Siri and Google Now are still in a very basic state of output, making it difficult to stick to users. Survey data shows that Siri can understand 83% of the questions, but the correct answer rate is only 62%.

Voice Control Smart Home - Personalized Recognition

When everyone speaks, the accent, speech rate, and mantra are different. It is obviously not enough for smart devices at home to recognize some basic phrases. They must understand you better. For example, to understand your accent, dialect, mantra, and professional vocabulary from time to time. Personalized recognition refers to the ability of a speech recognition system to automatically learn and adapt to user habits. The more you use it, the better it will understand you. In general, personalized recognition includes both pronunciation and language. The pronunciation pronunciation personalization mainly refers to the system's learning of pronunciation habits such as the user's speech rate, accent, etc., while the language individuation mainly means that the system can have better vocabulary for the user's specific vocabulary (eg, name, place name, mantra, professional vocabulary, etc.). Identification.
