AI Technical Summary

Problems solved by technology

During the application of ASR technology, due to the influence of background noise, or the influence of the speaker's pronunciation, such as dialect, accent, fast speaking, word usage habits, etc., there will inevitably be substitution, insertion or deletion errors in the ASR recognition results
These recognition errors will lead to problems such as improper word order, improper collocation, unclear semantics, and illogical sentences in the recognized sentences, forming wrong sentences.
These wrong sentences are not only difficult to understand and analyze, but also bring great difficulties to the subsequent application of Natural Language Processing (NLP).
In addition to the sentences obtained by ASR technology, the sentences entered manually in the computer may also have errors

Embodiment Construction

[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] The invention provides a wrong sentence detection method. refer to figure 1 As shown, it is a schematic flowchart of a wrong sentence detection method provided by an embodiment of the present invention. The method may be performed by a device, and the device may be implemented by software and / or hardware.

[0057] In this embodiment, the wrong sentence detection method includes:

[0058] Step S10, acquiring the target sentence obtained by the automatic speech recognition technology.

[0059] In this embodiment, the target sentence obtained by the automatic speech recognition (automatic speech recognition, ASR) technology may be one sentence or multiple sentences, and each sentence may be a long sentence or a short sentence. In other embodiments, the target sentence may also be a sentence input through other...

Abstract

The invention relates to the technical field of speech semantics, and discloses a wrong sentence detection method. The detection method includes the steps that a target sentence is obtained; i words included by the target sentence are identified; the i words are successively input into a pre-trained language model according to the order in the target sentence, and the confusion degree and / or logarithmic likelihood probability of the target sentence are / is calculated by the language model; and when the confusion degree of the target sentence is greater than the preset confusion degree and / or the logarithmic likelihood probability of the target sentence is less than the preset logarithmic likelihood probability, it is judged that the target sentence is a wrong sentence. The invention furtherprovides a wrong sentence detection device and a computer readable storage medium. According to the wrong sentence detection method and device, and the computer readable storage medium, whether a sentence is the wrong sentence or not can be identified.

Description

technical field [0001] The invention relates to the technical field of speech semantics, in particular to a wrong sentence detection method, device and computer-readable storage medium. Background technique [0002] With the development of technology, the automatic speech recognition (Automatic Speech Recognition, ASR) technology is more and more widely used. The ASR technology is a technology for converting human speech into text. During the application of ASR technology, due to the influence of background noise, or the influence of the speaker's pronunciation, such as dialect, accent, fast speaking, word usage habits, etc., substitution, insertion or deletion errors will inevitably occur in the ASR recognition results. These recognition errors will lead to problems such as improper word order, improper collocation, unclear semantics, and illogical sentences in the recognized sentences, resulting in wrong sentences. These wrong sentences are not only difficult to understan...
