Meeting Summarizer

Meeting Summarizer

Overview

Transform meeting recordings or transcripts into structured summaries: key decisions, action items with owners, discussion topics, and follow-up questions. Works from audio files (via Whisper) or raw text transcripts.

Transcribe Audio (Whisper)

import whisper
from pathlib import Path

def transcribe_audio(audio_path: str, model_size: str = "base") -> str:
    """Transcribe audio file to text using Whisper."""
    model = whisper.load_model(model_size)  # tiny/base/small/medium/large
    result = model.transcribe(audio_path, language="en")
    return result["text"]

# Install: pip install openai-whisper
# For GPU: pip install openai-whisper torch
