Speech input device for destination guidance system compares entered vocal expression with stored expressions for identification of entered destination

摘要

The speech input device has a speech recognition device for comparing an entered vocal expression identifying the required destination with stored vocal expressions, for classification according to the recognition probability, and selection of the stored expression exhibiting the highest recognition probability as the entered destination. Each stored vocal expression provides the destination name and additional regional information identifying the destination name, with storage of the destination names in one database (1) and storage of the additional regional information in a second database (2). An independent claim for a speech input method is also included.
