Multimodal Laryngoscopic Video Analysis for Assisted Diagnosis of Vocal Cord Paralysis
Zhang, Yucong, Zou, Xin, Yang, Jinshan, Chen, Wenjun, Liang, Faya, Li, Ming
This paper presents the Multimodal Analyzing System for Laryngoscope (MASL), a system that combines audio and video data to automatically extract key segments and metrics from laryngeal videostroboscopic videos for clinical assessment. MASL integrates glottis detection with keyword spotting to analyze patient vocalizations and refine video highlights for better inspection of vocal cord movements. The system includes a strobing video extraction module that identifies frames by analyzing hue, saturation, and value fluctuations. MASL also provides effective metrics for vocal cord paralysis detection, employing a two-stage glottis segmentation process using U-Net followed by diffusion-based refinement to reduce false positives. Instead of glottal area waveforms, MASL estimates anterior glottic angle waveforms (AGAW) from glottis masks, evaluating both left and right vocal cords to detect unilateral vocal cord paralysis (UVFP). By comparing AGAW variances, MASL distinguishes between left and right paralysis. Ablation studies and experiments on public and real-world datasets validate MASL's segmentation module and demonstrate its ability to provide reliable metrics for UVFP diagnosis.
RFK Jr. speaks candidly about his gravelly voice
There was a time before the turn of the millennium when Robert F. Kennedy Jr. gave a full-throated accounting of himself and the things he cared about. He recalls his voice then as "unusually strong," so much so that he could fill large auditoriums with his words. The independent presidential candidate recounts those times somewhat wistfully, telling interviewers that he "can't stand" the sound of his voice today -- sometimes choked, halting and slightly tremulous. Spasmodic dysphonia, a rare neurological condition, in which an abnormality in the brain's neural network results in involuntary spasms of the muscles that open or close the vocal cords. My my voice doesn't really get tired. "I feel sorry for the people who have to listen to me," Kennedy said in a phone interview with The Times, his voice sounding as strained as it does in his public appearances.
A New Artificial Intelligence Model Has Been Developed to Detect Covidโ19 Disease From Cough Sound
While scientists continue their fight against SARSโCoVโ2, one of the deadliest viruses in the last ten years, with antigen diagnostic tests, tests that help diagnose and prognosis, drugs, and vaccine inventions, informatics mostly continue to work on early detection diagnosis, prognosis, and prediction in this period. The aim is to reveal systems with a low margin of error that can help the workload of healthcare professionals and early diagnosis and initiation of treatment. The most commonly used computer vision (automation of the processes of vision and perception in humans, highโlevel interpretation on digital images or videos on the computer) is the processing of radiological images. Automation of the same image interpretation process for the performance of many applications and imaging results can be easily accomplished with complex and powerful computational platforms of largeโscale data such as Deep Learning. With deep understanding, the manual design of these features is eliminated, and a large amount of different classification and regression tasks are completed with higher accuracy.
Throat cancer: Signs and symptoms to look out for
Experts fear the U.S. will see thousands more cancer deaths in the coming years due to delayed screenings, treatments and trials; Dr. Marc Siegel reacts. Throat cancer is a term that can apply to several different types of cancers that occur in different locations in the head and neck. In 2018, more than 30,000 people in the U.S. received a throat cancer diagnosis of some kind, according to MD Anderson Cancer Center. Both laryngeal and hypopharyngeal cancers start in the lower part of the throat. Patients diagnosed with laryngeal cancer mean that the disease was detected in an area affecting the voice box, including the supraglottis, which is located above the vocal cords, the glottis, which contains the vocal cords or the subglottis, which is below the vocal cords, according to the American Cancer Society.
Politicians with hoarse voices win more votes
Margaret Thatcher's remarkable success at the ballot box may have been partially due to her distinctive voice, according to a new study. Experts looked at whether voters could be swayed by the way politicians speak. They found that politicians whose voices were hoarse, flat or slow received a better response from the public than those who had a different speech pattern. They believe this is because they are perceived as wiser and more competent than those who have a high-pitched voice. Margaret Thatcher's remarkable success at the ballot box may have been partially due to her distinctive voice, according to a new study.
A Glossary of Linguistic Terms
Warning: This web page was originally constructed to help computer science students who were taking my module on natural language processing. Some terms may be used differently by different authors. Unless otherwise stated, definitions are based on the English language. If you find any errors, please e-mail me at p.coxhead@cs.bham.ac.uk. The verb in an active sentence can be said to be in the active voice. Examples are colourless and green which qualify ideas in Colourless green ideas sleep furiously. Adjectives can also appear after verbs like be, e.g. Examples are furiously which qualifies the verb sleep in Colourless green ideas sleep furiously, or intensely which qualifies stared in He stared at me intensely. Adverbs can also qualify adjectives, e.g. Many English adverbs are formed from an adjective plus the ending -ly. Words like very, which can only qualify adjectives or adverbs but not verbs, are sometimes called adverbs, but are perhaps best put in a separate category. In its broadest sense, an affix can be a prefix, a suffix, or an infix. More narrowly, infixes are sometimes treated separately. The stop and fricative must be produced in a very similar positions in the mouth.
