Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0025] figure 1 It is an application environment diagram of the voice endpoint detection method at the vehicle terminal in an embodiment. refer to figure 1 , the voice endpoint detection method of the vehicle terminal is applied to the voice recognition system of the vehicle terminal. The speech recognition system includes a terminal 110 installed in the vehicle, and the terminal 110 automatically recognizes the speech in the vehicle. Specifically, when the current in-vehicle network status does not meet the preset online detection conditions and cannot perform online d...

Abstract

The present application relates to a method, device, computer-readable storage medium and computer equipment for detecting a voice endpoint of a vehicle-mounted terminal. The method includes: obtaining the current vehicle-mounted network status and the voice data stream to be detected; when determining that the current vehicle-mounted network status is not When the preset online detection conditions are met, the speech feature vector is extracted from the speech data stream; the speech feature vector is analyzed by the speech feature vector through the speech endpoint detection model of the vehicle, and the speech endpoint analysis result is obtained. The speech endpoint detection model is based on different environments. The obtained speech training data is trained; the speech endpoint in the speech data stream is determined according to the speech endpoint analysis result, and the speech endpoint detection result is obtained. The solution provided by this application can improve the accuracy of voice endpoint detection at the vehicle end.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a vehicle-end voice endpoint detection method, device, computer-readable storage medium and computer equipment. Background technique [0002] With the development of computer technology, speech recognition technology, also known as Automatic Speech Recognition (ASR), has received more and more attention. Speech recognition technology is a technology that allows machines to convert voice signals into corresponding text or commands through the process of recognition and understanding, which involves signal processing, pattern recognition, probability theory and information theory, vocal and auditory mechanisms, artificial intelligence and other fields. In speech recognition, it is necessary to detect a speech signal from continuous speech data through Voice activity detection (VAD), so as to perform subsequent recognition processing on the speech signal. The tradit...
