Limited word recognition
This article refers to the address: http://
According to the number of words, words or short sentences in the vocabulary, it is roughly divided into: 100 or less for small vocabulary; 100-1000 for medium vocabulary; and 1000 or more for large vocabulary.
Infinite vocabulary recognition (full syllable recognition)
When the recognition primitive is a readable syllable corresponding to all Chinese characters in Mandarin Chinese, it is called full-syllabic speech recognition (syllable word list: Lexicon). Full-syllable speech recognition is the basis for unlimited vocabulary or Chinese text input.
High Voltage Epoxy Resin Insulator
Insulators can be divided into low-voltage insulators and high-voltage insulators according to different voltage levels. High voltage insulator refers to the insulator used for high voltage and ultra-high voltage overhead transmission lines and substations. In order to meet the needs of different voltage levels, different numbers of single (piece) insulators of the same type are usually used to form insulator strings or multiple insulation poles.
Epoxy resin material has a series of outstanding advantages in organic insulation materials, such as high cohesion, strong adhesion, good flexibility, excellent heat curing performance and stable chemical corrosion resistance. It can be made into various solid materials by vacuum casting through epoxy resin casting system, such as automatic epoxy pressure gel manufacturing process (APG process). The epoxy resin insulation parts made of the epoxy resin have high mechanical strength, strong arc resistance, high compactness, smooth surface, good cold resistance, good heat resistance, good electrical insulation and other advantages, and are widely used in the power industry, mainly playing a supporting and insulating role.
