Embodiment Construction

[0043] In order to better understand the present invention, some basic concepts are firstly explained.

[0044] Open dictation: also known as continuous speech recognition, it is a recognition technology mainly used to recognize large segments of audio content, and can be widely used in text message dictation, voice chat, Weibo, etc.

[0045] Command word recognition: specifically refers to the speech recognition of some commands, such as performing operations on the computer, such as turning on, shutting down, opening Notepad, opening a browser, etc.

[0046] WER: word error rate, mainly for open dictation, because it is basically unfeasible to require sentence accuracy, so this indicator is used to measure it. The calculation formula is: 1-word accuracy. The formula for word accuracy rate is: (number of correct words recognized - number of wrong words inserted) / total number of recognized speech words*100%. The so-called inserting the wrong number of words means adding a re...

Abstract

The invention provides an automatic voice recognition effect testing system and an automatic voice recognition effect testing method. The automatic voice recognition effect testing system comprises an automatic configuration module, an automatic voice playing and recording module and a voice recognition and result statistic module. An operator only needs to prepare testing materials in advance, and the whole execution process is automatic, so that participation of persons is greatly reduced, the labor cost is reduced, repeated test and verification can be performed, large-scale test of few days and nights can be met, automatic statistic is performed on the testing result, manual error is avoided, and the testing efficiency and accuracy can be greatly improved. The system can be applied to equipment such as any desktop computer or notebook computer, and can be used for rapidly obtaining result data in terms of recognition effect evaluation, undertaking tasks which can not be finished by manpower and providing great convenience to each manufacturer.

Description

technical field [0001] The invention relates to a voice recognition effect automatic test system and a test method, belonging to the voice recognition technology. Background technique [0002] Speech recognition research began in the 1950s, initially to convert natural human speech into computer-readable input. [0003] The speech recognition system basically includes speech signal preprocessing and feature extraction, acoustic comparison, and language decoding. Feature extraction is to analyze and process the speech signal, properly remove redundant information that has nothing to do with speech recognition, and obtain important information that affects speech recognition. Acoustic contrast is the pattern matching of speech features to an acoustic model produced using a training algorithm. Language decoding is to use the grammatical network composed of recognized speech commands or the language model composed of statistical methods to perform grammatical and semantic anal...
