AI总结:

本研究提出了一种基于CRNN的语音语言识别方法,通过比较CNN和带注意力机制的CRNN,实现了对多种印度语言的高准确率识别,并在噪声环境下表现出良好的鲁棒性。

摘要:

语言识别(LID)是自动语音识别(ASR)领域中的关键初步过程,涉及从音频样本中识别出 spoken language。能够处理多语言语音的现代系统需要用户在使用前明确指定一种或多种语言。在多语言环境中,当ASR系统无法理解 spoken language 时,LID任务扮演着重要角色,导致语音识别结果失败。本研究介绍了一种基于卷积循环神经网络(CRNN)的LID方法,该方法针对音频样本的梅尔频率倒谱系数(MFCC)特征进行操作。此外,我们复制了某些最先进的方法,特别是卷积神经网络(CNN)和带有注意力机制的卷积循环神经网络(CRNN with attention),并进行了与我们CRNN方法的比较分析。我们对十三种不同的印度语言进行了全面评估,我们的模型实现了超过98%的分类准确率。LID模型在语言上相似的语言中表现出高水平的性能,范围从97%到100%。所提出的LID模型具有高度可扩展性,能够应用于额外的语言,并且在噪声环境下表现出强抗干扰能力,在应用于欧洲语言(EU)数据集时,其在噪声环境下的准确率为91.2%。

英文摘要:

Language Identification (LID) is a crucial preliminary process in the field of Automatic Speech Recognition (ASR) that involves the identification of a spoken language from audio samples. Contemporary systems that can process speech in multiple languages require users to expressly designate one or more languages prior to utilization. The LID task assumes a significant role in scenarios where ASR systems are unable to comprehend the spoken language in multilingual settings, leading to unsuccessful speech recognition outcomes. The present study introduces convolutional recurrent neural network (CRNN) based LID, designed to operate on the Mel-frequency Cepstral Coefficient (MFCC) characteristics of audio samples. Furthermore, we replicate certain state-of-the-art methodologies, specifically the Convolutional Neural Network (CNN) and Attention-based Convolutional Recurrent Neural Network (CRNN with attention), and conduct a comparative analysis with our CRNN-based approach. We conducted comprehensive evaluations on thirteen distinct Indian languages and our model resulted in over 98\% classification accuracy. The LID model exhibits high-performance levels ranging from 97% to 100% for languages that are linguistically similar. The proposed LID model exhibits a high degree of extensibility to additional languages and demonstrates a strong resistance to noise, achieving 91.2% accuracy in a noisy setting when applied to a European Language (EU) dataset.
