In this paper, we propose a new more generic and more efficient attack method that can be used to promote the security of intelligent speech systems. By turning the attack target into a holistic intelligent speech system, we discovered security threats in speech resampling and risks in deep model normalization layers, and designed CA-ISS algorithms based on these two security risks. CA-ISS algorithm results in semantic content changes after speech resampling and launches an attack by creating cognitive differences between human and deep models. This paper also upgrades to the limitations of CA-ISS algorithm to attack the cloud platforms. Six intelligent speech systems are used to verify the effectiveness of CA-ISS in experiments. Experimental results demonstrate that the CA-ISS algorithm has sufficient generalisability, efficiency, and camouflage. Finally, the principle of CA-ISS algorithm is analyzed based on multiple visualization algorithms and the camouflage effect of the attack samples is evaluated.</div></div>","PeriodicalId":49485,"journal":{"name":"Speech Communication","volume":"166 ","pages":"Article 103152"},"PeriodicalIF":2.4,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The widespread recognition of the popularity of SER among academics for three decades is mainly attributed to its broad application in practical scenarios. The utilization of SER has proven to be beneficial in various fields, such as medical intervention, bolstering safety strategies, conducting vigil functions, enhancing online search engines, enhancing road safety, managing customer relationships, strengthening the connection between machines and humans, and numerous other domains. Many researchers have used diverse methodologies, such as the integration of different attributes, the use of different feature selection techniques, and designed a hybrid or complex model using more than one classifier, to augment the effectiveness of emotion classification. In our study, we used a novel technique called the fixed frequency range empirical wavelet transform (FFREWT) filter bank decomposition method to extract the features, and then used those features to accurately identify each and every emotion in the speech signal. The FFREWT filter bank method segments the speech signal frame (SSF) into many sub-signals or modes. We used each FFREWT-based decomposed mode to get features like the mel frequency cepstral coefficient (MFCC), approximate entropy (ApEn), permutation entropy (PrEn), and increment entropy (IrEn). We then used the different combinations of the proposed FFREWT-based feature sets and the deep neural network (DNN) classifier to classify the speech emotion. Our proposed method helps to achieve an emotion classification accuracy of 89.35%, 84.69%, and 100% using the combinations of the proposed FFREWT-based feature (MFCC + ApEn + PrEn + IrEn) for the EMO-DB, EMOVO, and TESS datasets, respectively. Our experimental results were compared with the other methods, and we found that the proposed FFREWT-based feature combinations with a DNN classifier performed better than the state-of-the-art methods in SER.</div></div>","PeriodicalId":49485,"journal":{"name":"Speech Communication","volume":"166 ","pages":"Article 103148"},"PeriodicalIF":2.4,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method integrates a convolutional module into the Transformer framework to enhance its capacity for local feature modeling, enabling to extract both local and global information from speech signals simultaneously.

This study adopted an orthogonal design with four participant groups, namely, Mandarin-L1 monolinguals and Mandarin-L1 and Cantonese-L2 bilinguals with or without musical training, to investigate effects of bilingualism and musicianship on perception of non-native lexical tones. The closely matched four groups, each encompassing an equal number of 20 participants, attended a modified ABX discrimination task of lexical tones of Teochew, which was unknown to all participants and consists of multiple tone types of level tones, contour tones, and checked tones. The tone perceptual sensitivity index of <em>d’</em> values and response times were calculated and compared using linear mixed-effects models. Results on tone sensitivity and response time revealed that all groups were more sensitive to contour tones than level tones, indicating the effect of native phonology of Mandarin tones on non-native tone perception. Besides, as compared to monolinguals, bilinguals obtained a higher <em>d’</em> value when discriminating non-native tones, and musically trained bilinguals responded faster than their non-musician peers. It indicates that bilinguals enjoy a perceptual advantage in non-native tone perception, with musicianship further enhancing this advantage. This extends prior studies by showing that an L2 with a more intricate tone inventory than L1 could facilitate listeners’ non-native tone perception.

However, the current screening system for OSA does not have an objective assessment of the upper airway. The assessment of the upper airway can accurately be performed by MRI or CT scans, which are costly and not easily accessible. Acoustic pharyngometry or Ultrasonography could be less expensive technologies, but these require trained personnel which makes these technologies not easily accessible, especially when assessing the upper airway in a clinic environment or before surgery. In this study, we aimed to investigate the utility of vowel articulation in assessing the upper airway dimension during normal breathing. To accomplish that, we measured the upper airway cross-sectional area (UA-XSA) by acoustic pharyngometry and then asked the participants to produce 5 vowels for 3 s and recorded them with a microphone. We extracted 710 acoustic features from all vowels and compared these features with UA-XSA and developed regression models to estimate the UA-XSA. Our results showed that Mel frequency cepstral coefficients (MFCC) were the most dominant features of vowels, as 7 out of 9 features were from MFCC in the main feature set. The multiple regression analysis showed that the combination of the acoustic features with the anthropometric features achieved an R² of 0.80 in estimating UA-XSA. The important advantage of acoustic analysis of vowel sounds is that it is simple and can be easily implemented in wearable devices or mobile applications. Such acoustic-based technologies can be accessible in different clinical settings such as the intensive care unit and can be used in remote areas. Thus, these results could be used to develop user-friendly applications to use the acoustic features and demographical information to estimate the UA-XSA.</div></div>","PeriodicalId":49485,"journal":{"name":"Speech Communication","volume":"165 ","pages":"Article 103144"},"PeriodicalIF":2.4,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142423404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a zero-shot VC method based on feature disentanglement. The proposed model uses a speaker encoder for extracting speaker embeddings, introduces mixed speaker layer normalization to eliminate residual speaker information in content encoding, and employs adaptive attention weight normalization for conversion. Furthermore, dynamic convolution is introduced to improve speech content modeling while requiring a small number of parameters. The experiments demonstrate that performance of the proposed model is superior to several state-of-the-art models, achieving both high similarity with the target speaker and intelligibility.
