Abstract

The invention discloses an automatic voice data labeling method and system for voice recognition, and particularly relates to the field of voice recognition. The system comprises a mute detection module, a volume screening module, a length screening module, a voice recognition module, a recognition result judgment module and a manual proofreading module, the mute detection module splits each voiceinto a plurality of voice segments through a mute detection algorithm, and the volume screening module is used for screening out voices meeting the requirements through a volume threshold value and removing voices not meeting the requirements. The invention discloses a combined system of multiple modules. According to the system, speech preprocessing and speech recognition are carried out, by a public cloud mode, recognition result judgment manual proofreading are carried out, voice data annotation is constructed, after multiple times of iteration of the processes, a new corpus is continuously trained, high-quality corpus data is obtained, manpower is reduced, the voice data annotation quality is improved, and the problems that the manual annotation period is long, the cost is high and the efficiency is low are solved.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, and more specifically, the present invention relates to a method and system for automatic marking of speech data for speech recognition. Background technique [0002] Speech data labeling, speech recognition performance and robustness largely depend on whether there is accurately labeled corpus data during the modeling process of the recognition model. Traditional voice data labeling is generally done manually, which consumes a lot of manpower physical resources. VAD (Voice Activity Detection), voice activity detection, is a technology for voice processing, the purpose is to detect the presence of voice signals, VAD technology is mainly used for voice coding and voice recognition. [0003] With the popularization of various smart terminals and breakthroughs in artificial intelligence technology, voice, as an important part of human-computer interaction, is widely used in vario...
