# 🎙️ English Accent Audio Detector

This Streamlit web application detects the English accent of a speaker in a video or audio file. It leverages pre-trained machine learning models and allows users to upload a video or input a YouTube URL. The app extracts and trims the audio, transcribes the speech, filters for English language, and then predicts the accent from a set of common English accents.

🚀 Features
* ✅ Upload videos or provide YouTube/video url links

* 🎧 Automatic audio extraction and trimming (max 2 minutes)

* 🗣️ Transcription and English language filtering

* 🧠 Accent classification using a Wav2Vec2-based model

* 💬 Clear display of the speaker's accent and confidence score

### 🧪 Model Information
This app uses the Accent-ID model developed by Juan Pablo Zuluaga on the CommonAccent dataset.

The model is implemented using the SpeechBrain toolkit, a powerful open-source speech processing framework built on PyTorch.

### 🚀 How to Use
* Run the app:

* Choose Input Method:

  * Upload a video file (.mp4, .mov, .avi, .mkv)
