bongovaad (বঙ্গবাদ)

bongovaad is a Python package for transcribing Bengali audio from YouTube videos. It uses the Hugging Face Inference API with Whisper models for high-quality speech recognition.

Features

• Cloud-based Transcription: Uses Hugging Face Inference API with state-of-the-art Whisper models.
• SRT Subtitle Generation: Automatically creates SRT subtitle files for video players.
• Efficient Audio Processing: Handles audio segmentation for longer videos with progress tracking.
• Concurrent Processing: Uses asynchronous requests for faster transcription of multiple segments.
• Temporary File Management: Uses temporary directories for clean processing.
• Robust Error Handling: Comprehensive error handling and logging.
• Command-line Interface: Easy-to-use CLI with multiple options.

Requirements

• Python 3.8 or higher
• Hugging Face API key
• ffmpeg

Installation

1. Install ffmpeg

Ubuntu/Debian:

sudo apt install ffmpeg -y

macOS (using Homebrew):

brew install ffmpeg

Windows (using Chocolatey):

choco install ffmpeg

2. Install bongovaad

pip install bongovaad

3. Get a Hugging Face API Key

1. Create an account on Hugging Face
2. Generate an API key at https://huggingface.co/settings/tokens
3. Set it as an environment variable:

export HF_API_KEY="your_api_key_here"

Usage

Basic Usage

bongovaad --url "https://www.youtube.com/watch?v=VIDEO_ID"

Advanced Options

bongovaad --url "https://www.youtube.com/watch?v=VIDEO_ID" \
          --segment-length 10 \
          --output-format both \
          --model-id "openai/whisper-large-v3-turbo" \
          --api-key "your_api_key_here" \
          --verbose

Command-line Arguments

Output Files

The tool generates two types of output files:

1. Text File (VIDEO_ID.txt): Contains the full transcription text.
2. SRT File (VIDEO_ID.srt): Contains time-coded subtitles compatible with video players.

Python API

You can also use bongovaad as a Python library:

import os
from bongovaad import BongoVaadTranscriber

# Get API key from environment variable or set it directly
api_key = os.environ.get("HF_API_KEY", "your_api_key_here")

# Initialize the transcriber
transcriber = BongoVaadTranscriber(
    api_key=api_key,
    model_id="openai/whisper-large-v3-turbo"
)

# Transcribe a YouTube video
output_files = transcriber.transcribe(
    url="https://www.youtube.com/watch?v=VIDEO_ID",
    segment_length_seconds=10,
    output_format="both"
)

# Print output file paths
print(f"Text file: {output_files['txt']}")
print(f"SRT file: {output_files['srt']}")

Performance Considerations

• Processing time depends on video length, internet connection, and Hugging Face API response times.
• Longer segment lengths may improve speed but could reduce accuracy for complex audio.
• The API has rate limits, so be mindful of how many requests you make.
