acoustic mismatch 中文意思是什麼
acoustic mismatch
解釋
聲失配-
The model of the itr between a1n and cu is built by using the acoustic mismatch model, amm and diffuse mismatch model, dmm. because there is a limit of roughness and temperature in amm and dmm, the data of the theory model that is directly built by amm and dmm is far from the experimental data. accordingly, with dmm and traditionary methods, the mathematics model is posed by contrast and analyses of the experiment data
由於聲失配理論和散聲失配理論對溫度和粗糙度有很嚴格的要求，所以直接建模所得的理論數據與實驗數據有很大的差距，本文採用聲失配理論與傳統研究方法相結合，通過與實驗數據的分析擬合，提出了修正的數學模型，預測誤差有了大幅度的提高。 -
Prevailing speech recognition systems can obtain a very high accuracy for clean speech recognition, but their performance will degrade rapidly in noisy environments owing to the mismatch between the acoustic models and the testing speech
目前的語音識別系統對純凈語音可以達到非常高的識別精度，但是無處不在噪聲帶來了訓練模型和測試語音之間的失配，識別器的性能在噪聲環境中將會急劇下降。 -
Because noise causes the mismatch between the acoustic models and the testing speech, the performance of speech recognition systems will degrade rapidly in noisy environments. therefore, noise robust technology is a very crucial problem for the speech recognition
目前的連續語音識別系統對純凈語音已能達到非常高的識別精度，但是無處不在的背景噪聲帶來了訓練模型和測試語音之間的失配，這種失配使得連續語音識別系統的性能在噪聲環境中急劇下降。
