Develop a TV and radio audio monitoring system capable of detecting specific keywords (e.g., “India”) in live or recorded audio streams, and automatically notify the user via an API or webhook whenever a keyword is detected. ⸻ Technical Architecture 1. Audio/Video Sources • Live or delayed streams from TV and radio stations. • Can include IP streams (RTMP, HLS, etc.) or locally recorded files. 2. Speech-to-Text Module • Uses services such as Whisper (OpenAI), Google Speech-to-Text, Azure Speech Services, or Deepgram. • Real-time or near real-time transcription of audio content. 3. Keyword Filtering • Analyzes the transcribed text to detect predefined keywords (e.g., “India”, “Modi”, “Delhi”…). • Multilingual support depending on the transcription model. 4. API / Webhook Notifications • When a keyword is detected, the system sends a webhook call or updates an API with the following data: { "timestamp": "2025-05-09T18:45:00Z", "media_type": "radio", "channel_name": "BBC World Service", "keyword": "India", "excerpt": "Today, in India, the new economic reform...", "language": "English", "confidence": 0.92, "audio_url": "[login to view URL]" } 5. Admin Interface (optional) • To add/remove keywords. • To view detection history. • To configure API/webhook endpoints. ⸻ Technical Deliverables • Webhook or RESTful API to receive alerts. • Option to configure a callback URL. • Technical documentation (OpenAPI/Swagger) for integration. ⸻ Technical Requirements • Access to TV/Radio streams (via IP TV service) • Cloud servers or infrastructure capable of running transcription models. • A stream processing or message queue system (e.g., Kafka or RabbitMQ) to handle large volumes of audio. ⸻

⭐⭐⭐⭐⭐ CnELIndia, under the leadership of Raman Ladhani, can deliver a robust solution for the "Keyword Detection in TV/Radio Audio Monitoring" project. We would start by integrating live or delayed audio streams from TV and radio sources, including RTMP and HLS. Using speech-to-text services like Whisper or Google Speech-to-Text, we’ll ensure real-time or near-real-time transcription. Our team will then implement a keyword detection module, capable of processing multiple languages, and extract specific keywords such as "India" and "Modi" from the transcriptions. Upon detecting a keyword, we will configure an API/webhook to send relevant data, including timestamps, channel details, and the audio snippet. Additionally, we will develop an admin interface to allow easy keyword management, with support for setting callback URLs and viewing detection history. Leveraging cloud servers and stream processing technologies like Kafka, CnELIndia will ensure scalability and efficient handling of high-volume audio streams.

@Penmate

Hello there! I understand you're seeking the development of a robust TV and radio audio monitoring system that can detect specific keywords (like "India") from live or recorded streams and trigger real-time notifications via webhook or API. This solution requires accurate transcription, multilingual support, stream handling at scale, and reliable event delivery—backed by scalable cloud infrastructure. To design and implement a system tailored to your needs: Are you already subscribed to any IP stream providers (e.g., IPTV services or cloud DVRs) that we can connect to for ingesting media? Should the system support only English initially, or do you want multilingual transcription and keyword detection from the start? Do you prefer a managed transcription API (like Google, Azure) or a self-hosted option like Whisper for more control and cost flexibility? Here's my portfolio for your review: https://www.freelancer.com/u/Penmate. Please feel free to message me to explore your infrastructure preferences and timeline for delivering this scalable, keyword-aware monitoring system! Best regards, Bryson Henniger

⚠ NO PAYMENT UNLESS YOU'RE SATISFIED ⚠ Hey! I’ve built real-time media monitoring systems with Whisper and Deepgram for keyword detection, including multilingual and API-triggered alerts—exactly like what you described. I can set up stream ingestion, transcription, filtering, and a webhook-ready backend with logging. Are you already using an IP TV service or need help sourcing reliable live stream feeds?

Hello Ben Fraj E.! ➡️I have hands-on experience building real-time speech-to-text pipelines and scalable alert systems for multilingual media analysis as audio monitoring and keyword detection system with Techniques I Will Use: ✅Audio Stream Ingestion: Capture live HLS, RTMP, and local media using FFmpeg with failover handling for unstable streams. ✅Real-Time Transcription: Deploy Whisper on GPU-backed instances (or Deepgram API for scalable alternatives) to transcribe streams in multiple languages. ✅Keyword Detection: Use NLP tools (spaCy, regex, Levenshtein) on transcripts with fuzzy logic for near-match accuracy. ✅Webhook/API Alerts: JSON-based notifications with keyword, timestamp, and audio snippet using Flask + Swagger/OpenAPI for integration. ✅Stream Pipeline: Kafka or Redis Streams to buffer, process, and distribute audio events across scalable consumers. ✅Optional Admin Panel: Built in Streamlit or React for managing keywords and viewing historical logs. ➡️Similar Projects: ✅“Arabic-English Broadcast Monitoring System” – Whisper + keyword detection across multi-language satellite channels with Twilio alert integration. ✅“Audio Keyword Trigger for Radio Compliance” – On-premise Whisper transcription of regional FM recordings with auto-alert system. ➡️I am from India, GMT +5:30, and I am available from 8:00 a.m. to 11:00 p.m. We have 16+ years of experience and developed over 600 projects & research papers.

I previously faced challenges with keyword detection in real-time audio streams, specifically dealing with background noise and variable audio quality; I resolved this by using advanced noise reduction techniques. I understand you need a system that detects keywords like "India" in live or recorded TV and radio audio. My proposal includes a reliable speech-to-text module that provides real-time transcriptions. I will implement a robust keyword filtering mechanism and API/webhook notifications for immediate alerts. This project can be executed on cloud servers with a message queue to ensure smooth processing.
