从专利申请分析欧洲智能语音技术的发展

Analyzing Development Situation of European Intelligent Speech Technology from Patent Application

通过搜集、整理和分析智能语音专利数据,了解欧洲智能语音技术的发展现状及趋势,并结合文献检索结果,通过专利信息的检索、清洗、标引建立专利数据库。从专利视角,借助专利分析方法深入剖析欧洲智能语音技术专利申请趋势、关键技术、主要竞争者、重点专利。分析结果发现,语音合成技术和语音识别技术发展较为成熟,自然语言理解技术发展潜力巨大,飞利浦公司竞争实力较强,美国和日本企业注重在欧洲进行专利布局,从专利保护角度进行分析研究可以更加客观地反映欧洲智能语音技术发展态势。

This paper aims to understand the European intelligent speech technology development present situation and trend by collecting, sorting and analyzing intelligent speech patent data, combined with the results of literature retrieval, through retrieval, cleaning and indexing of the patent information to set up patent database, analyze deeply patent application trend, key technology, main competitors, key patents of European intelligent speech from the perspective of patent technology. In this paper, with the aid of patent analysis, we can find out speech synthesis and speech recognition have well developed, natural language understanding technology development potential is huge, PHILPS’ competitive power is stronger, the United States and Japan's enterprises pay attention to in Europe for patent layout, we can more objectively reflect the European intelligent speech technology development trend from the perspective of patent protection. Due to the delay of the patent information data, analyzing intelligent speech technology development has a certain limitation.
