Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] figure 1 For a flow chart of a data labeling method disclosed in an embodiment of the present invention, see figure 1 As shown, data labeling methods can include:

[0053] Step 101: Align and label the wake-up word data to obtain initial label data.

[0054] Wherein, the wake-up word data may specifically be voice data. For example, for a certain function or a certain electronic device, if the text content corresponding to the wake-up voice is "Hello...

Abstract

The invention discloses a data labeling method and device, and the method comprises the following steps: carrying out the alignment labeling of wake-up word data, and obtaining initial labeling data;training based on the initial labeling data to obtain a first wake-up model; traversing awakening word data which is not subjected to alignment labeling based on the first wake-up model, and determining an awakening word data set which can be successfully awakened; and performing alignment labeling on the wake-up words in the wake-up word data set based on the first wake-up model. According to thedata labeling method and device, the wake-up model is trained based on the initial labeling data, and then the matched wake-up words are labeled based on the special wake-up model, so that the labeling accuracy of the wake-up words is improved.

Description

technical field [0001] The present invention relates to data processing technology, more specifically, to a data labeling method and device. Background technique [0002] Speech recognition technology has been widely used in electronic devices with various functions, bringing convenient and high-quality interactive experience to users. Generally, an electronic device will automatically enter a dormant state after a non-working state lasts for a certain period of time. When a user wants to enter a working state, it needs to be woken up first. [0003] The process of device wake-up needs to be implemented based on the wake-up model. During the training period of the wake-up model, well-labeled data is required, and whether the data labeling is accurate directly affects the accuracy of the final wake-up model. In the prior art, the labeling of data is to align and label the wake-up data (a piece of speech) through a recognition model. The label is a speech frame-level label, ...
