In today’s digital landscape, hate speech is an escalating concern, often fueling division and unrest across communities. DweshaMukt is an Advanced Multilingual and Multimodal Hate Speech Detection System designed to counteract this issue by harnessing the power of Bidirectional Encoder Representations from Transformers (BERT) alongside cutting-edge Deep Learning and Natural Language Processing (NLP) techniques.
Our system tackles a unique challenge: detecting hate speech within Hinglish—a dynamic blend of Hindi and English—while also supporting Hindi and English languages individually. DweshaMukt leverages a pre-trained BERT model, specially optimized for real-time scenarios, offering robust analysis across a range of media. Its Multilingual and Multimodal architecture enables Hate Speech Detection across diverse content types: Text, Audios, Images, Videos, GIFs, and YouTube Comments.
With an accuracy of 88%, DweshaMukt stands as a promising solution for real-world hate speech detection applications, bridging language and media barriers to ensure safer, more inclusive online spaces.

Completing this project was indeed a challenging task, and we deeply appreciate Prof. Rajkumar Panchal Sir for being our mentor. He guided us through every phase of the project, and his support was invaluable.
Hate speech detection has become a critical area of research in recent years, driven by the proliferation of social media platforms where users frequently engage in discussions that transcend linguistic boundaries. This has created unique challenges, particularly in detecting hate speech within code-switched and multilingual contexts. Numerous studies have tackled this issue by employing advanced machine learning and deep learning techniques, striving to enhance the accuracy and robustness of hate speech classifiers. This section highlights significant contributions in this field, with a focus on methodologies and outcomes that address the complexities of hate speech detection in mixed-language data.
Our model processes multiple media types for hate speech detection:
This pipeline integrates NLP and DL techniques for detecting hate speech in Hinglish, leveraging BERT for multilingual and code-mixed processing with robust performance across diverse media types.
The backend development was an intricate journey, involving months of rigorous research, experimentation, and iterative coding. Each phase contributed to refining the system’s ability to detect hate speech across various input types and languages.
Our Mark Model Index Document provides a comprehensive overview of this journey, showcasing each model’s evolution, from early concepts to the final optimized versions. Dive into the document to see how each model was crafted, tested, and fine-tuned to tackle the challenges of multilingual, multimodal hate speech detection.
The backend architecture of DweshaMukt enables the system to classify various forms of input text, audio, video, images, GIFs, and live YouTube comments by first converting each to text before applying the hate speech detection model. Here are the main scenarios handled by the system:
Google Speech to Text API, then classifies it.Google Cloud Vision API.Google Video Intelligence API for text extraction.pytchat library, then classifies them.The combined code integrates all these scenarios into a unified detection system, including added emoticon-based classification for enhanced accuracy.
The DweshaMukt Dataset is a curated collection of comments carefully selected to support research on hate speech detection. This dataset includes multilingual data in Hinglish, Hindi, and English, capturing various instances of hate and non-hate speech. It is a valuable resource for researchers and developers working on projects aimed at building safer online communities.

We utilized the following datasets:
Combined Dataset Summary:
This setup enabled efficient training and testing of the hate speech detection model with a focus on robust performance in identifying hate and non-hate content.
The performance of our model on the test set is summarized in the table below:
The overall accuracy of our model is 0.88, with a macro average of 0.59 and a weighted average of 0.88.
Model Performance
Precision and Recall:
- Hate (Yes): Precision = 0.85, Recall = 0.88
- Non-Hate (No): Precision = 0.91, Recall = 0.88
These results demonstrate the model’s robustness in identifying hate speech, making it highly effective for monitoring social media.
This study introduces a multimodal and multilingual hate speech detection model leveraging BERT and advanced NLP techniques. By integrating textual and non-textual data—including images, videos, emoticons, memes, and YouTube comments—the model significantly enhances hate speech detection across diverse contexts. Key highlights include:
The DweshaMukt project is integrated with Telegram through a series of specialized bots, each designed to handle a different type of input. This allows users to classify text, audio, images, GIFs, video, and YouTube comments directly within the Telegram platform.
| Bot Name | Description | Watch in Action |
|---|---|---|
| Haspe Text | Processes text input. |  |
| Haspe Audio | Processes audio input. |  |
| Haspe Image | Processes image input. |  |
| Haspe GIF | Processes GIF input. |  |
| Haspe Video | Processes video input. |  |
| Haspe YouTube | Processes YouTube live comments. |  |
Each bot seamlessly interacts with the backend, delivering real-time classification results to users. Whether you're analyzing text, multimedia, or live YouTube comments, these bots ensure a versatile and accessible experience for hate speech detection.
The DweshaMukt project was proudly showcased at the Nexus 1.0 State Level Project Competition on 15th April 2024.
