Abstract

The invention provides a method for correcting error-prone words in voice interaction. The method comprises the steps of context recognition, automatic error correction based on semantic restriction, and artificial error correction based on semantic feedback. Through voice interaction with users and perception and recognition of the context of a topic, automatic error correction of an entity with a specific meaning can be achieved by using the named entity recognition technology within the limited semantic range, additional semantics can be obtained through artificial feedback so as to conduct error correction, and higher input efficiency and more convenient wrong word correction than existing voice recognition software are realized.

Description

technical field [0001] The present invention relates to typo-prone calibration technology, in particular, to a method for calibrating typo-prone characters in voice interaction, especially applying the natural language understanding method to the calibration and correction of typo-prone characters in voice interaction, realizing a usable calibration of typo-prone characters in voice interaction plan. Background technique [0002] As a new way of human-computer interaction, voice interaction has been widely used in recent years. This first stems from the development of speech recognition technology, from Hidden Markov Model (HMM), Gaussian Mixture Model (GMM) to the current Deep Neural Network (DNN), speech The error rate of the recognition system has dropped significantly; secondly, the usage habits of smart device users have not yet formed, and new technologies such as voice interaction are easy to be accepted by the public; and the extraordinary development of cloud compu...
