Description
Technical field
The present invention relates to the audio signal processing technique field, particularly a kind of recording detecting method, device and examination terminal and examination system.
Background technology
The development of technology such as modern computer and speech recognition, the technique guarantee means being provided and having implemented guarantee for no paper examination.SETs such as for example, mandarin test, Foreigh-language oral-speech examination also adopt with no paper machine to examine in succession.The with no paper machine of SET is examined and is: the examinee by earphone listening to audio form examination paper and be recorded on the examination terminal by the answer of headset with audio format, the teacher that gos over examination papers listens to the answer of recording on the examination terminal by earphone and examinee's spoken language proficiency is marked or carries out machine robotization scoring.
The with no paper machine of SET is passed the examination, headset is a kind of key equipment, the answer whether headset can effectively receive the examinee will directly influence the examinee and whether can finish answer smoothly, the answer of recording by headset whether enough clear will directly the influence go over examination papers and examinee's achievement.In various SETs, that headset inserts is bad, heterophemia, recording obstacle etc. are influence the principal element that the examinee normally takes an examination.Therefore, pass the examination at the with no paper machine of SET, all need before the examination headset on the examination terminal is carried out environment measuring.
At present, pass the examination all to adopt manually at the with no paper machine of SET headset is carried out environment measuring.Concrete, manually one by one the headset on every the terminal of taking an examination being carried out audition and detect with recording, whether normally complete tester judges headset.
Adopt artificial headset to the examination terminal to detect and mainly have following deficiency:
At first, when manually headset being tested, testing result subjective lacks qualitative analysis and quantized result, and current sound, anti-neighbourhood noise etc. is also lacked objective evaluation, causes testing result inaccurate.
Secondly, adopt manual detection, 60 people examination halls need just can finish the headset environment measuring more than two hours usually, even sometimes needing three people to finish the detection of a headset jointly, detection efficiency is very low, and takes time and effort, it is also higher to detect cost, is unsuitable for large-scale promotion.
The 3rd, because environmental change (as the increase of large contingent noise etc.), normal headset when manually carrying out the headset environment measuring tends to during examination go wrong, and detects the fault rate height, also can directly influence the carrying out of examination in the examination process.
Summary of the invention
The invention provides a kind of recording detecting method, device and examination terminal and examination system, testing result is inaccurate when solving on the examination terminal headset environment measuring, detection efficiency is low, it is high and detect the high problem of fault rate to detect cost.
