Embodiment Construction

[0042] figure 1 It is a flow chart of the voice command word recognition method of the present invention.

[0043] To make the explanation clearer, in some places, the application of controlling the movement of the cart with voice commands is used as an example.

[0044] like figure 1 As shown, the method includes the following steps:

[0045] Step 1, determine whether the speech command word recognition model (new model) constructed this time needs to be incrementally constructed based on the existing speech command word recognition model (old model), if necessary, go to step 2; if not, go to step 2 3.

[0046] When building a speech command word recognition model, if it is necessary to add new command words on the basis of the existing model, an incremental construction method should be adopted.

[0047] Step 2, define the command word set containing the command words of the old model and the newly added command words here cmd i ,1≤i≤n 1 Represents a command word deriv...

Abstract

The invention provides a method for incremental voice command word recognition, comprising: step 1, judging whether the voice command word recognition model (new model) constructed this time needs to be augmented based on the existing voice command word recognition model (old model) Quantitative construction, if necessary, go to step 2, if not, go to step 3; step 2, define the command word set including the command words of the old model and the newly added command words; step 3, define only the newly added commands The command word collection of word; Step 4, build input is the voice data, the output is the deep neural network model of prediction category; Step 5, obtain training data, train this deep neural network model, obtain the well-trained voice command word recognition model; Step 6. Select a part of the data from the training data to enter the sample pool.

Description

technical field [0001] The invention relates to a processing method for incremental speech recognition based on deep neural network and incremental learning, and more particularly, to a method for incremental speech command word recognition based on deep learning. Background technique [0002] In recent years, deep learning has developed rapidly and has been applied to the fields of image recognition and speech recognition, achieving a level that surpasses that of humans. [0003] In many scenarios, there is an urgent need to give the machine an order to follow the instructions to complete a specific task. Since complete speech recognition technology is in the hands of tech giants and requires a networked environment to perform speech recognition, even if it can run locally, it requires a lot of computing resources. In addition, in these scenarios, full speech recognition capabilities are not required, and only certain commands need to be "understood" by the machine. [00...
