Voice control method for lighting lamp

Abstract

The invention provides a voice control method of a lighting lamp. The method includes the steps that a voice recognition chip is arranged in the lighting lamp; the voice recognition chip acquires user-defined voice flow of a user, a voice feature value is generated according to the user-defined voice flow, and the voice feature value is stored; the voice recognition chip acquires first voice flow input externally, and whether a first feature statement matched with the voice feature value exists in the first voice flow or not is judged; if the first feature statement exists, the voice recognition chip acquires second voice flow input externally within a preset time, and whether a second feature statement exists in the second voice flow or not is judged; if the second feature statement exists, a control command for changing the working state of the lighting lamp is generated according to the second feature statement. By means of the voice control method, the accuracy of voice control and user experience of the lighting lamp can be improved.

Description

technical field [0001] The invention relates to the technical field of voice control, in particular to a voice control method for lighting fixtures. Background technique [0002] With the development of voice recognition technology, it is considered in the prior art to introduce a voice control function into lighting fixtures, so that users can control operations such as on, off, and dimming of lighting fixtures by speaking voice control commands. [0003] Considering that lighting fixtures are not expected to limit the identity of users who control them by voice, but users who tend to realize any accent, age group, gender and vocal characteristics can control them by voice, so in lighting fixtures The method for implementing voice control is usually to use a non-person-specific voice recognition chip to recognize voice control commands. In practical applications, such non-person-specific speech recognition chips are often required to maintain a high speech recognition rate...

AI Technical Summary

Problems solved by technology

This kind of non-specific person voice recognition chip can increase the voice recognition rate while reducing the rejection rate, but it will increase the misrecognition rate, that is, the non-specific person voice recognition chip can easily convert other voices in normal conversations in the working scene of lighting fixtures or Irrelevant noise misidentified as a voice command, resulting in lighting fixtures being turned on, off, dimmed, etc. incorrectly, affecting user experience and reducing the efficiency of voice-controlled lighting fixtures
