Technology Pipeline for Large Scale Cross-Lingual Dubbing of Lecture Videos into Multiple Indian Languages

Cross-lingual dubbing of lecture videos requires the transcription of the original audio, correction and removal of disfluencies, domain term discovery, text-to-text translation into the target language, chunking of text using target language rhythm, text-to-speech synthesis followed by isochronous lipsyncing to the original video. This task becomes challenging when the source and target languages belong to different language families, resulting in differences in generated audio duration. This is further compounded by the original speaker's rhythm, especially for extempore speech. This paper describes the challenges in regenerating English lecture videos in Indian languages semi-automatically. A prototype is developed for dubbing lectures into 9 Indian languages. A mean-opinion-score (MOS) is obtained for two languages, Hindi and Tamil, on two different courses. The output video is compared with the original video in terms of MOS (1-5) and lip synchronisation with scores of 4.09 and 3.74, respectively. The human effort also reduces by 75%

Validation of Hindi version of oral health impact profile-14 for adults

Introduction: Oral health has an impact on overall general health. It is important to assess the influence of these oral disorders on quality of life. Aim: To validate a Hindi version of the oral health impact profile-14 (OHIP-14) and to assess the instrument's psychometric properties in the Indian population. Materials and Methods: A cross-sectional study was performed in Moradabad city with a sample of 186 participants. The same individuals underwent clinical examinations by a calibrated dentist for recording simplified oral hygiene index (OHI-S) index. The OHIP was initially translated and cross-culturally adapted to Hindi following guidelines; then, subsequently validated for the psychometric characteristics of reliability and validity. The reliability of the OHIP-14 was assessed by the use of Cronbach's coefficient. Reproducibility was evaluated by measuring test-retest reliability (intraclass correlation coefficient). Results: The overall value of Cronbach's alpha (α) coefficient of the OHIP-14 was estimated to be 0.8. The corrected item-total correlation coefficients values were above 0.2 that has been recommended for including an item in a scale. All Spearman's rank correlation coefficients were statistically significant, whereas the highest association was detected within the physical disability subscale (rs = 0.37), and the lowest within the social disability (rs = 0.08). It was seen that the OHIP-14 scores were higher for those individuals who had higher OHI-S scores and vice-versa. Conclusion: The translated Hindi version of OHIP-14 questionnaire is a reliable and valid instrument to measure the oral health-related quality of life in the Indian adult population

Dental Caries Experience among 12 Year Old School Children from Macedonia and India

The aim of the present study was to compare the dental caries status of the 12 year old children of the eastern region of Macedonia and Budgam district of Jammu and Kashmir state of India.Material and Method: In this comparative study (N=396) 12-year old children from Macedonia and 592 from India were included. Dental status of participants was evaluated using the 2013 World Health Organization caries diagnostic criteria for Decayed, Missing or Filled Teeth (DMFT) by 2 calibrated examiners in Macedonia and by the single examiner in India.Results: The mean value of the DMFT index for the whole sample of India was 1.91 ± 1.76 whereas for Macedonia it was 3.46 ± 2.90, and the difference was statistically significant (p&lt;0.001). In the Indian sample, 152 (25.68%) and in Macedonia sample 81 (21.46%) of the individuals were caries free (DMFT=0).In both countries, the female children have higher mean DMFT values. The filled component of DMFT was more among the Macedonian children which shows the higher utilization rates of dental care in that region in comparison to Indian counterparts.Conclusion: The mean DMFT of children from Macedonia was higher in comparison with children from India. The most possible reason for this can be the fact that sugar consumption in India was less in comparison with Macedonia.</p
