Data were collected through semi-structured questionnaire and interview of the informants including indigenous people, tribal people, and traditional health practitioners residing in the study area.Results: The present study documented etnobotanical uses of 86 plant species belonging to81 genera and 47 families. This study revealed that most of the species were used medicinally(74 spp; 42.29%). Leaves found to be the most frequently used part(56 spp., 36.13%) for preparation of indigenous recipes and fodder purpose.Conclusions: The current research provides a huge lump of ethnobotanical knowledge and depicts strong human-plant interaction. It is an urgent need to document indigenous uses of plants for future domestication.展开更多

The pitch is a fundamental attribute employed in numerous speech-related works. For fundamental frequency extraction, several algorithms have been developed which one to use relies on the signal’s characteristics and the surrounding noise. Thus, the algorithm’s noise resistance becomes more critical than ever for precise fundamental frequency estimation. Nonetheless, numerous state-of-the-art algorithms face struggles in achieving satisfying outcomes when confronted with speech recordings that are noisy with low signal-to-noise ratio (SNR) values. Also, most of the recent techniques utilize different frame lengths for pitch extraction. From this point of view, This research considers different frame lengths on male and female speech signals for fundamental frequency extraction. Also, analyze the frame length dependency on the speech signal analytically to understand which frame length is more suitable and effective for male and female speech signals specifically. For the validation of our idea, we have utilized the conventional autocorrelation function (ACF), and state-of-the-art method BaNa. This study puts out a potent idea that will work better for speech processing applications in noisy speech. From experimental results, the proposed idea represents which frame length is more appropriate for male and female speech signals in noisy environments.展开更多
