Any-to-any voice conversion using representation separation auto-encoder by Zhihua JIAN, Zixu ZHANG

“…In view of the problem that it was difficult to separate speaker personality characteristics from semantic content information in any-to-any voice conversion under non-parallel corpus, which led to unsatisfied performance, a voice conversion method, called RSAE-VC (representation separation auto-encoder voice conversion) was proposed.The speaker’s personality characteristics in the speech were regarded as time invariant and the content information as time variant, and the instance normalization and activation guidance layer were used in the encoder to separate them from each other.Then the content information of the source speech and the personality characteristics of the target one was utilized to synthesize the converted speech by the decoder.The experimental results demonstrate that RSAE-VC has an average reduction of 3.11% and 2.41% in Mel cepstral distance and root mean square error of pitch frequency respectively, and has an increasement of 5.22% in MOS and 8.45% in ABX, compared with the AGAIN-VC (activation guidance and adaptive instance normalization voice conversion) method.In RSAE-VC, self-content loss is applied to make the converted speech reserve more content information, and self-speaker loss is used to separate the speaker personality characteristics from the speech better, which ensure the speaker personality characteristics be left in the content information as little as possible, and the conversion performance is improved.…”

Differentiated services dynamic spectrum access strategy for cognitive wireless mesh network by Rui-fang LI, Quan LIU, Ren-fa LI

“…Dynamic spectrum access (DSA) is an important design aspect for cognitive radio network.Common access of multi-type services having different quality of service (QoS) requirements is the important characteristic of cognitive wireless mesh network.Differentiated service (DS) is the key to realize the high efficiency use of spectrum resources and to guarantee the high quality transmission of services.In order to satisfy the demand for multi-type services,a differentiated services dynamic spectrum access strategy was proposed.In this strategy,the unlicensed user traffic was divided into three priority classes.The DSA scheme uses different access mechanisms for the three classes of unlicensed users.The real-time traffic selectes available channel set according to the shortest expected delay to reduce the transmission time and the probability of appearance of licensed user during data transmission process.The general traffic selectes the channel of largest successful transmission probability to avoid spectrum handoff.The theoretical and experimental results show that,when compared with the traditional cognitive networks DSA strategy,the proposed strategy is able to guarantee different QoS for the various services,shorter transmission delay for higher priority services,reducing the probability of transmission interruption and better throughput performance when the vacancy rate of licensed channel is major and heavy network load.…”

User authentication of industrial internet based on HHT transform of mouse behavior by Yigong ZHANG, Qian YI, Jian LI, Congbo LI, Aijun YIN, Shuping YI

“…The rapid development of the industrial internet had caused widespread concern about the network security, and the end-user authentication technology was considered a research hotspot.According to the characteristics of human-computer interaction in industrial internet, an experimental website was designed.24 users' mouse behavior data in an uncontrolled environment were collected within 2.5 years to conduct case studies.Hilbert-Huang transform (HHT) was used to extract frequency domain features of mouse behavior signals, combined with time domain features to form a time-frequency joint domain feature matrix of 163-dimensional to characterize user mouse behavior patterns.Bagged tree, support vector machine (SVM), Boost tree and K-nearest neighbor (KNN) were used to build a user authentication model， and the comparison result showed that the Bagged tree had the best internal detection effect in this case, with an average false acceptance rate (FAR) of 0.12% and an average false rejection rate (FRR) of 0.28%.In external detection, the FAR was 1.47%.Compared with the traditional mouse dynamics method, the frequency domain information of mouse behavior extracted by HHT can better realize the user authentication, and provide technical support the security of the industrial internet.…”
