• Computer Speech

  Xiaomi voice technology provides Xiaomi with speech recognition, voice wake-up, voiceprint recognition, spoken language evaluation, spoken language recognition, voice emotion recognition, speech synthesis, and songs Speech understanding and generation technologies such as synthesis, AI arrangement and composition.

• NLP

  Xiaomi NLP (Natural Language Processing) technology is committed to providing Xiaomi with NLP foundation, content understanding, human-computer dialogue, machine translation and other technologies. From the technical fields of lexical analysis, syntactic analysis, document analysis and semantic analysis, we provide basic natural language processing technical support for search, recommendation, advertising, human-computer dialogue and other businesses.

  Among them, based on the mainstream Transformer model framework, Xiaomi has independently developed the Xiaomi translation system, which already supports mainstream languages ​​​​such as Chinese, English, Japanese, Korean, German, Russian, Hindi, Indonesian, Cantonese, French, and Spanish. Interpretation. At the same time, focusing on the needs of Xiaomi users, it has self-developed cutting-edge machine translation capabilities such as anti-noise voice translation, multi-lingual on-device offline translation, and simultaneous interpretation. It has been widely used in Xiaomi products, including the Xiaoai voice assistant, browser, scan and portal applications in mobile phones, a variety of smart hardware with built-in Xiaoai classmates, Xiaoai teacher learning machines, and Xiaomi.com International Customer service and other international businesses.

• Knowledge Graph

  Xiaomi’s knowledge graph technology aims to build a comprehensive knowledge network and help partners’ products become smarter through knowledge understanding. Relying on massive data, we comprehensively use technologies such as knowledge extraction, entity normalization, knowledge calculation and reasoning, and concept mapping. Allow users to model the real world in an intelligent way, understand and meet user needs.

  Xiaomi Knowledge Graph has a complete construction system and a sound open content ecosystem. The ecological field covers general domain knowledge and products, games, and application apps such as characters, constellations, attractions, videos, music, cars, and real estate. and other industry domain knowledge. The extensive application of services in multiple field scenarios of intelligent Q&A and Xiaoai classmates has played a key role in improving user satisfaction and business transformation capabilities. In terms of knowledge openness, we have cooperated with OpenKG to support the construction of OpenBase, an open domain knowledge graph with Chinese as the core.
  

• Voice quick operation
