About IFLYTEK

Speech and language are the most natural and convenient way for human beings to communicate and obtain information, as well as the foundation of culture and the symbol of a nation. The intelligent speech and language interaction technology has a great application prospect in all aspects of the society, especially in such strategic areas as military, education, and promotion of Chinese in the world. Therefore, it has been a highly competitive area both at home and abroad.

Carrying out the principles of “from the market, to the market” and “use the right methods and do the meaningful research”, iFLYTEK has been dedicated to building up its competitive edges in the intelligent speech and language technology and the industrialization of its core technologic achievements. At present, iFLYTEK has established core competence in such technology areas as speech recognition, text to speech, comprehension of natural language, speech evaluation, voiceprint recognition, and handwriting recognition. iFLYTEK has been providing the international leading total speech and language solutions and launching the intelligent speech and language technology products and application services to meet the requirements of the State and society.

The description of the main core technology hkust xunfei as follows: 科大讯飞的主要核心技术
Speech recognition technology
Speech recognition technology

The speech recognition technology aims to equip a computer with ears so that the computer can hear the speech of human beings and extract text information from the speech. Therefore, it enables human-machine communication and interaction based on the most natural and convenient means of speech. The technology plays an important role in intelligent computer systems (that can hear and talk).

Speech synthesis technology
Speech synthesis technology

Also known as the Text to Speech (TTS) technology, it is a mix of technologies in multiple fields including acoustics, linguistics, digital signal processing, and computer sciences. Its main function is to convert text into intelligible voices, in other words, let machines talk like human beings.

Natural language processing technology
Natural language processing technology

This technology involves a wide research scope which, based on the forms of research achievements, can be categorized into:
Fundamental research: Refers to the research on the inherent laws of natural languages, which can be further divided into lexicography, sentence splitting, part of speech analysis, language model, syntax analysis, semantic analysis, pragmatic analysis, etc. based on the level and difficulty of the research.
Application research: Refers to the research on related natural language processing technologies specific to different applications based on the results of fundamental research. The major research subjects include, without limitations to, Pinyin input method, information retrieval, information extraction, automatic summarization, machine translation, speech synthesis, speech recognition, text match, text classification, dialog system, etc.

Speech evaluation technology
Speech evaluation technology

Also known as the Computer Assisted Language Learning, this technology enables a machine to automatically evaluate the pronunciation of a user, check for errors, and provide correction suggestions. The speech evaluation technology is on the cutting edge of the intelligent speech processing field, and has a good application prospect as it can remarkably improve the interest, efficiency, and effectiveness of the audiences in learning a spoken language.

Voiceprint recognition technology
Voiceprint recognition technology

This technology can determine the identity of a speaker by extracting the identity-related characteristics (for example, pitch, which can reflect the glottis opening and closing frequency, and spectrum, which can reflect the size and shape of the mouth and the length of the sound track) of the speaker from the speech signals. This technology can find wide application in information security, telephone banking, intelligent access control, and value-added entertainment fields.

Handwriting recognition technology
Handwriting recognition technology

This technology enables a computer to recognize the text written by a user on a handwriting input device, and convert the orderly handwriting tracks into characters. Compared with traditional input modes, this technology provides users with a more convenient interaction mode on such mobile terminals as smart phones and tablet PCs, enabling users unfamiliar with keypad operations to use various electronic devices easily and conveniently.
