ABOUT

Across schools in India, CCTV surveillance systems have long been used to ensure student safety. Mandated by the Central Board of Secondary Education, these systems allowed schools to monitor visual activity across classrooms and campuses. However, while schools could see what was happening, they could never truly hear it. Monitoring audio feeds across multiple classrooms simultaneously was humanly impossible, leaving a critical blind spot where verbal bullying continued to remain invisible and unaddressed.

From body shaming and racist remarks to sexism, homophobia, exclusionary behaviour, and inappropriate comments, verbal bullying often exists within everyday conversations, leaving deep emotional and psychological impact while escaping institutional awareness. Unlike physical bullying, it leaves no visible evidence. Harmful behaviour develops gradually through repeated language, emotional intimidation, and social exclusion, making early intervention extremely difficult. At the same time, most counselling frameworks relied on broad, one size fits all interventions that failed to account for differences in age, emotional maturity, and evolving behavioural patterns across grades.

To address this challenge, D.A.V. Public School collaborated with Classteacher to create Bullying Decoder, an AI-powered safeguarding solution that transforms existing CCTV infrastructure into an intelligent behavioural insight system. Instead of requiring new hardware, the solution activated unused audio feeds already available within classroom surveillance systems and converted them into a source of real time behavioural intelligence.

Powered by advanced AI trained on more than 60,900 hours of real classroom audio, Bullying Decoder was designed to understand not only words, but also tone, emotional intensity, repetition, and conversational context across India’s multilingual classrooms. Unlike traditional moderation systems that rely solely on keyword detection, the AI interprets intent and identifies subtle forms of verbal harm including body shaming, sexism, racism, exclusionary behaviour, and emotionally harmful speech patterns that conventional surveillance systems fail to detect.

Importantly, the system was designed with a strong privacy first approach. It does not record or store raw audio, transcripts, or student identities. Instead, classroom interactions are processed in real time and converted into anonymised behavioural indicators displayed through a structured dashboard that highlights emotional sentiment trends, bullying intensity levels, and behavioural patterns across classes and grades.

These insights enabled educators and counsellors to identify behavioural risks earlier and design targeted, age appropriate interventions before harmful behaviour escalated. As a result, counselling at D.A.V. Public School evolved from a reactive disciplinary process into a proactive emotional safeguarding framework driven by real behavioural insight.

During the 2025 to 2026 academic session, Bullying Decoder identified 75,798 bullying related incidents, enabling the school to detect harmful patterns significantly earlier than before. This early visibility contributed to a 54% reduction in verbal bullying overall. Counsellors also gained a clearer understanding of emotional dynamics across different grades and classroom environments, allowing them to deliver more effective and personalised interventions.

The initiative also strengthened trust among parents and the wider community. D.A.V. Public School recorded a 20% increase in admission applications compared to the previous academic year, reflecting growing confidence in the school’s commitment to emotional safety and student wellbeing.

Following these early successes, Bullying Decoder received recognition from India’s State Education Ministry and Oman’s Ministry of Education, helping establish the initiative as a new model for emotional safeguarding in schools.

More than 10 schools across India have since entered adoption discussions, supporting the phased expansion of the platform nationwide and demonstrating its potential to reshape how educational institutions detect, understand, and prevent verbal bullying at scale.

Kyoorius Creative Awards, powered by The Clio Awards, honoured Bullying Decoder with 10 Elephants — the festival’s coveted trophies — recognising the initiative as one of India’s most outstanding pieces of creative work.
