This document presents a proposed system for performing sentiment analysis on audio and video reviews from social media platforms. The system first collects audio and video data from sites like YouTube and Facebook. It then separates the audio and video files, converts them to .wav format, and extracts text from the audio and video files. This extracted text is then analyzed using the VADER sentiment analysis algorithm to determine the sentiment polarity (positive, negative, neutral) expressed in the text. VADER is a lexicon-based approach that rates words based on sentiment and calculates overall sentiment scores. The proposed system aims to analyze sentiment in audio and video reviews to better understand user opinions expressed across various social media platforms.

Sentiment analysis tools for software engineering research cannot be used out...Alexander Serebrenik
Recent years have seen an increasing attention to social aspects of software engineering, including studies of emotions and sentiments experienced and expressed by the software developers. Most of these studies reuse existing sentiment analysis tools such as SentiStrength and NLTK. However, these tools have been trained on product reviews and movie reviews and, therefore, their results might not be applicable in the software engineering domain.
In this paper we study whether the sentiment analysis tools agree with the sentiment recognized by human evaluators (as reported in an earlier study) as well as with each other. Furthermore, we evaluate the impact of the choice of a sentiment analysis tool on software engineering studies by conducting a simple study of differences in issue resolution times for positive, negative and neutral texts. We repeat the study for seven datasets (issue trackers and STACK OVERFLOW questions) and different
sentiment analysis tools and observe that the disagreement between the tools can lead to contradictory conclusions.Ijsrdv8 i10424
