Aiming at the low confidence of traditional spoken English automatic evaluation methods, this study designs an automatic evaluation method of spoken English based on multimodal discourse analysis theory. This evaluation method uses sound sensors to collect spoken English pronunciation signals, decomposes the spoken English speech signals by multilayer wavelet feature scale transform, and carries out adaptive filter detection and spectrum analysis on spoken English speech signals according to the results of feature decomposition. Based on multimodal discourse analysis theory, this evaluation method can extract the automatic evaluation features of spoken English and automatically recognize the speech quality according to the results. The experimental results show that, compared with the control group, the designed evaluation method has obvious advantages in confidence evaluation and can solve the problem of low confidence of traditional oral automatic evaluation methods.

This paper provides a comprehensive explanation of the theoretical foundations of multimodal discourse analysis theory as applied to speaking instructional design. The specific application of multimodal theory in the teaching of elementary English speaking classrooms is explored through the teaching design of elementary English speaking classrooms, the teaching implementation of multimodal teaching design is carried out, and the effect of the teaching practice of elementary English speaking guided by multimodal discourse analysis theory is comprehensively evaluated through classroom observation method, questionnaire survey method, and interview method, combined with the teaching evaluation and teaching implementation effect, which is the multimodal teaching design. The paper also summarizes the findings and shortcomings of the study. Through the teaching design and implementation, the advantages of multimodal teaching are obvious; it can combine with modern advanced teaching techniques to create more realistic communicative situations in the classroom, gather and present various modal resources and information, and ensure rich and diverse language input; students can receive various sensory stimuli in the classroom, deepen their memory and experience of language, increase the interest of classroom teaching, and improve students’ participation. It also increases the interest of the classroom and enhances students’ participation and motivation. Based on multimodal theory, the author designed a multimodal teaching framework for a semester-long speaking course in the speaking classroom for reference. The fuzzy measures were constructed based on subsets of language segments containing 10 phonemes belonging to the same HDP set. Finally, linguistic scores are given by the Surgeon integral model based on the plausibility of the system and the fuzzy measures. The experimental results based on Sphinx-4 show that the evaluation model yields plausible and stable evaluation results for the 3 test sets at an average correct recognition rate of 84.7% of phonemes.

This qualitative study examined multimodal cohesive devices in English oral biology texts by eight high-achieving Saudi English-as-a-foreign-language students enrolled in a Bachelor of Science Dentistry program. A Systemic Functional Multimodal Discourse Analysis (SF-MDA) of the textual and logical cohesive devices in oral biology texts was conducted, employing Halliday and Hasan’s cohesion analysis scheme. The findings showed that students used varied cohesive devices: lexical cohesion, followed by reference and conjunctions. Although ellipsis was minimally employed in the oral biology texts, its discipline-specific uses emerged: the use of bullet points and numbered lists that facilitate recall. The SF-MDA of cohesion in multimodal semiotic resources highlighted the processes underlying construction of conceptual and linguistic knowledge of cohesive devices in oral biology texts. The results indicate that oral biology discourse is interdisciplinary, including a number of subfields in biology. The SF-MDA of pictorial oral biology representations indicates that they include instances of cohesive devices that illustrate and complement verbal texts. The results indicate that undergraduate students need to be provided with a variety of multimodal high-cohesion texts so that they can successfully extend underlying conceptual and logical meaning-making relations.

AbstractThis study aims to investigate the process of reconstruction of Māori postcolonial cultural identity in the twenty-first century which also passes through the reclamation and redefinition of ‘takatāpui’ notion. ‘Takatāpui’ is an umbrella term that nowadays indicates all the Māori with non-conforming wairua (spiritualities, gender identities), sexualities and sex characteristics. It is a culturally specific word which represents a form of intersectionality by identifying people as both Māori and queer.As a consequence of the increasing spread of the Internet, which has become a virtual place to construe identity and to promote the dissemination of ideas, a Multimodal Discourse Analysis is conducted on a corpus comprising 10 audiovisual texts fully retrieved from the web and exclusively produced by Māori takatāpui activists and/or containing Māori takatāpui activists’ self-narratives or claims.The corpus is analysed by applying a MMDA (Multimodal Discourse Analysis) framework based on Kress and van Leeuwen’s social semiotic framework (2006). The analysis is conducted also by taking into account Blommaert’s linguistic and ethnographic framework (2014).The findings of the analysis show the different strategies through which Māori identities are construed and conveyed reinforcing what the Māori scholar, Tuhiwai Smith (1999. Decolonizing Methodologies: Research and Indigenous Peoples. Dunedin: Zed Books Limited, 28), calls “a very powerful need to give testimony to and restore a spirit, to bring back into existence a world fragmenting and dying”.

Heroic narratives are often biased towards a conceptualization of the rural/urban difference that positions rural identities at the margins. In particular, superhero stories have traditionally offered a vision of heroism assumed to be male, urban and young. How can post-rural contexts shaped by migration contest these narrative patterns? This article examines the street narrative of Fenómenas do rural, which recognizes older female rural identities and casts them as superheroines. Through a multimodal discourse analysis, I examine its contestation of heroic patterns, its recognition of older female rural identities and its creation of affiliation opportunities for the Galician community. I argue that this narrative stands as a reflection of the rurban (rural + urban) and the glocal (global + local) elements that subverts pre-existing canons in the superhero and the meiga (‘witch’) mythology imaginaries.

The main goal of college English education is to cultivate the students’ language ability of listening, speaking, reading and writing, and to promote the formation of individualized learning and autonomous ability of college students. At present, the new curriculum reform in our country has put forward a new educational requirement to college English teaching, which requires the innovation of college English teaching idea, and under the background of the development of new media, it proposes to use new media equipment to carry out teaching activities. However, college English education in our country is influenced by examination-oriented education mode, and the traditional education method is still used, which is not good for college students to improve their comprehensive quality of English. In view of this development situation, the Ministry of Education of China Based on the development of new media, a multimodal discourse analysis approach to college English education is proposed to enhance the level of College English teaching.

BACKGROUND Gangstalking refers to a novel persecutory belief system wherein sufferers believe that they are being followed, watched, and harassed by a vast network of people in their community who have been recruited as complicit perpetrators. They are frequently diagnosed as mentally ill, though they vehemently reject this formulation. Those affected by this belief system self-identify as targeted individuals. Targeted individuals seek to prove the veracity of their persecution and dispute the notion that they are mentally ill by posting videos online that purport to provide definitive evidence to substantiate their claims of harassment. OBJECTIVE The objective of the study was to characterize the multimodal social semiotic practices employed in gangstalking evidence videos. METHODS We assembled a group of 50 evidence videos posted on YouTube by self-identified targeted individuals. We performed a multimodal discourse analysis on a corpus of 50 YouTube vlogs. We employed a grounded theory approach to data analysis. RESULTS Targeted individuals accomplished several social and interpersonal tasks in the videos. They constructed their own identity as subjects of persecution and refuted the notion that they suffered from mental illness. They also cultivated positive ambient affiliation with viewers of the videos but manifested hostility to people who appeared in the videos. They made extensive use of multimodal deixis to generate salience and construe the gangstalking belief system. The act of filming itself was a source of conflict and served as a self-fulfilling prophecy; filming was undertaken to neutrally record hostility directed towards vloggers. However, the act of filming precipitated the very behaviours that they set out to document. Finally, the act of filming was also regarded as an act of resistance and empowerment by vloggers. CONCLUSIONS This data provides valuable insights into the social and linguistics construction of a novel persecutory belief system. The data is collected in a naturalistic setting and is not influenced by interviewers or clinicians, which may influence the disclosures of those affected in clinical settings. It demonstrated that interpersonal concerns figured prominently for those affected by this belief system and they constructed various subjects as either sympathetic or hostile. They created positive ambient affiliation with viewers of the videos. This study found that vloggers used multimodal deixis to construct the salience of the gangstalking belief system. The videos also highlighted the Derridean concept of differance, wherein meaning of polysemous signifiers is deferred without definitive resolution. This may have important clinical ramification in communicating with people and patients suffering from persecutory belief systems. Clinicians working with adherents to persecutory belief systems may consider stepping away from the traditional true/false dichotomy historically endorsed by psychiatric classification systems and focus on the fundamental ambiguity inherent in semiotic systems generally and in persecutory belief systems specifically.
