Abstract: Methods, systems, and a non-transitory computer storage media storing computer-useable instructions are provided to ensure quality of experience (QoE) for extended reality (XR) devices over WiFi networks. A WiFi connectivity device receives a pairing request from an XR device. The pairing request contains an XR identifier that indicates one or more service needs of the XR device and identifies a priority of the XR device for data rate and bandwidth assignment. A negotiating agent, which can reside in the XR device or the WiFi connectivity device, negotiates a channel selection for the XR device. The channel selection negotiated is based on the XR identifier. After negotiation is complete, the XR device pairs with the WiFi connectivity device and receives scheduled transmissions on the negotiated channel.

This application has the characteristics of uniform light emission and good heat dissipation effect.

Abstract: A high-fidelity AsCpf1 mutant is obtained by performing a mutation on arginine at position 951 and/or 955 of a AsCpf1 protein amino acid sequence and replacing the same with an amino acid free of forming a hydrogen bond with DNA of a target site; and the amino acid sequence thereof is shown in SEQ ID NOS: 1-3. The encoding gene of the AsCpf1 mutant has a nucleotide sequence as shown in SEQ ID NO: 4 and can be used in the construction of a CRISPR/AsCpf1 gene editing system. A CRISPR/AsCpf1 gene editing system includes a gene encoding a AsCpf1 protein, and the AsCpf1 protein is the AsCpf1 mutant mentioned above. The CRISPR/AsCpf1 gene editing system can be used in lowering an off-target effect of gene editing. The novel AsCpf1 mutant not only retains the gene editing efficiency of wild-type AsCpf1, but also has a higher specificity than the wild-type AsCpf1.

Abstract: An aerial imaging element in a teleprompter system, a teleprompter and a teleprompter device includes one or more optical elements that bend incident light of an image and form a real image in the air, and further includes one or more translucent reflectors. The aerial imaging element is convenient to manufacture and is low in cost; the aerial imaging element enables an image displayed therein to form a real image in the air, which can be seen only at a certain angle. The aerial imaging element is applied to the prompt of aspects, such as news broadcasting and lecture giving, which is convenient and does not influence viewing or video recording at the scene.

Abstract: Voice processing methods and systems are provided. An utterance is received. The utterance is compared with teaching materials according to at least one matching algorithm to obtain a plurality of matching values corresponding to a plurality of voice units of the utterance. Respective voice units are scored in at least one first scoring item according to the matching values and a personified voice scoring algorithm. The personified voice scoring algorithm is generated according to training utterances corresponding to at least one training sentence in a phonetic-balanced sentence set of a plurality of learners and at least one real teacher, and scores corresponding to the respective voice units of the training utterances of the learners in the first scoring item provided by the real teacher.

Abstract: The present invention is directed to a method for speech-based information retrieval in Mandarin Chinese, considering a monosyllabic structure of the Chinese language, and a whole class of syllable-based indexing terms, including overlapping segments of syllables and syllable pairs separated by a few syllables. The strong discriminating capabilities of such syllable-based indexing, terms have been verified. Special approaches for better utilizing such capabilities, including fusion with the word- and character-level information and improved approaches to obtain better syllable-based features and query expressions and so on, are disclosed too.

Abstract: A mandarin speech input method for directly translating arbitrary sentences of mandarin speech into corresponding Chinese Characters. The present invention is capable of processing a sequence of "mono-syllables," "(but each of the characters in the poly-character word is continuous)," "prosodic segments," or even a "whole sentence of continuous mandarin speech." A prosodic segment comprising one or more words is a segment that is automatically isolated by a speaker by pausing where characters in the prosodic segment are continuous.

Abstract: A Mandarin speech input system and method for directly translating arbitrary sentences of Mandarin speech into corresponding Chinese characters is disclosed. The system and method comprises acoustic processing section and linguistic decoding section. The acoustic processing step employs "Segmental Probability Models" to calculate the probabilities of each of the mono-syllables in the Mandarin speech input and each of the tones thereof for further recognition. The linguistic decoding step employs "Word-class-based Chinese Language Models" to locate the corresponding Chinese characters for the series of recognized syllables provided by said acoustic processing step. A Mandarin dictation machine translates the provided speeches into characters in accordance with above method and displays the characters.

Abstract: The present invention relates to speech scrambling techniques and systems and in particular to a frequency or time domain speech scrambling technique and system which does not require any frame synchronization. This invention is technique and system for scrambling speech signal in frequency or time domain by means of speech analysis-synthesis techniques. The system described above is very attractive because it has avoided the frame synchronization problem. The existing analog telephone channel can be utilized directly for transmission because bandwidth expansion is completely controllable. In addition, the "key space" is very large and a high degree of security can be achieved.
