Time series signal recognizing device
专利汇可以提供Time series signal recognizing device专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a voice recognizing device having a high recognition performance by which it is unnecessary to detect a start and an end of a voice by preparing separately data of a noise, etc. which become a factor of generation of a pattern formation, and repeating a recognition based on an artificial pattern deformation and a continuous pattern collation and an automatic extraction of a learning use voice feature vector.
CONSTITUTION: This device is provided with an input means 4 for inputting time series data such as voice data, etc., and an analyzing means 5 for analyzing the time series data and deriving the time series data of a feature parameter. Also, this device is provided with a collating means 6 for collecting successively a series of fixed dimension feature vectors selected and combined successively from in the time series data of the feature parameter and a recognition use dictionary and deriving a time series value of similarity. Moreover, this device is provided with a deciding means 8 for recognizing the time series data inputted from the time series value of similarity, an extracting means 14 for extracting a learning use fixed dimension feature vector from the time series data of the feature parameter, and a working means 12 for applying an artificial pattern deformation to a reference pattern of the time series data. In such a way, even under the condition that a pattern deformation of a time series signal is large, a high recognition rate is obtained.
