Embodiment Construction

[0036] The method for updating the function of the embedded speech recognition system proposed by the present invention obtains the update data through the network or other approaches such as the local file system, and then according to the information provided by the update data, mainly relies on the speech training function module of the speech recognition program to update the existing function is updated. The function update described here refers to changing the original function by means of deleting, modifying or overwriting. In this embodiment, the function is updated through overwriting. Other ways can be deduced like this. Speech recognition systems are divided into continuous speech recognition systems and isolated word recognition systems according to the continuity of input speech. Isolated word recognition is also called keyword recognition. Keyword recognition refers to, given a set of keywords and its pre-trained information results (codebook) including feature ...

Abstract

The invention discloses a method used for updating the functions of an embedded speech recognition system. The invention comprises the steps as follows: a function updating request is initiated by the system; the present speech recognition program is halted and the present data is backed up; updating data are obtained by the network or a local file system; the obtained updating data are checked; speech recognition training is carried out according to the updating data and the training result is stored; and the system with updated functions is operated. By adopting the method used for updating the functions of the embedded speech recognition system of the invention, updating can be carried out on the functions of the system by the user without changing the speech recognition program maintained in the embedded system, thereby improving user experience of the product and raising value of the product.

Description

technical field [0001] The invention relates to a method for updating the function of an embedded speech recognition system, in particular to a method for realizing system function updating without updating a speech recognition program. Background technique [0002] Speech recognition technology has been developed since the 1950s. So far, it has been relatively mature in theoretical research. However, it has not been widely used for a long time due to the constraints of many factors such as hardware performance, cost and market demand. With the improvement of chip integration and performance and the continuous development of embedded systems, these unfavorable factors are gradually alleviated and eliminated, which greatly promotes the development of speech recognition products. In the embedded speech recognition system, the small vocabulary speech recognition system can generally meet the requirements, and such systems can usually recognize the speech of dozens of keywords. ...
