【摘要】：利用inco Pat科技创新情报平台对智能语音领域专利信息进行检索,经过清洗、标引形成数据库并进行分析,以了解中国智能语音技术的研发态势、技术布局、竞争格局。分析表明,2000年以来中国智能语音领域专利申请处于快速增长阶段,2000-2011年处于技术成长期,2011年之后处于技术换代期。中国智能语音领域专利申请集中在语音识别系统中的后端处理、声学模型、降噪处理等方面。自然语言理解专利申请年均增长率最高,是新的研发热点。将专利权人研究强度分为专注型、新秀型、奠基型和追随型,并据此对全球语音关键技术专利申请排名前25位专利权人进行了分类,其中的3位中国专利权人分布于新秀型和专注型。美国和中国是全球智能语音领域的主要竞争者。中国国内机构海外专利申请数量较少,在智能语音产业链上的参与企业数量、类型仍然偏少。
[Abstract]:The use of Inco Pat technology innovation platform for information retrieval, intelligent voice in the field of patent information after cleaning, the formation of database indexing and analysis, in order to understand the China intelligent speech technology research situation, technology layout, competition pattern. The results show that, since 2000, the patent Chinese intelligent voice application field in the stage of rapid growth, 2000-2011 years in the growth period in 2011, after the technology updating period. The back-end processing, China patent application focused on the field of intelligent voice speech recognition system in the acoustic model, denoising processing. The natural language understanding of an application for a patent for the highest annual growth rate, is a new research focus. The patentee of strength is divided into focus type, rookie, foundation type and the following, and the key technology for global patent top 25 patent classification, 3 of them Chinese patent People are distributed in rookie and focus. The US and China are the main competitors in the field of intelligent voice in the world. The number of overseas patent applications in China is relatively small, and the number of enterprises participating in the intelligent voice industry chain is still relatively small.
