PDF to Podcast is an AI tool by NVIDIA that converts PDF documents into engaging audio content, such as podcasts, using large language models and text-to-speech technology.
What is PDF to Podcast?
PDF to Podcast is an AI tool developed by NVIDIA that transforms PDF documents into engaging audio content, such as podcasts. Built on NVIDIA's NIM microservice architecture, it leverages large language models (LLMs) and text-to-speech (TTS) technology to extract content from PDFs, convert it into Markdown format, and generate natural-sounding audio in the form of dialogues or monologues.
Key Features
- PDF to Markdown Conversion: Extracts content from PDFs and converts it into Markdown format for further processing.
- Generate Dialogues or Monologues: AI processes Markdown content to generate natural, fluid audio scripts.
- Text-to-Speech (TTS): Converts processed text content into high-quality speech.
Technical Details
- NVIDIA NIM Microservices: Uses Llama 3.1 series models for inference.
- Document Parsing: Uses Docling for PDF to Markdown conversion.
- Speech Synthesis: Uses ElevenLabs for text-to-speech conversion.
- Storage and Caching: Uses MinIO and Redis.
Deployment Methods
- Using NVIDIA API Catalog: No local GPU hardware required; all model inference is done on NVIDIA's cloud infrastructure.
- Local Deployment of NVIDIA NIM: For higher performance and privacy, NVIDIA NIM can be deployed locally, but it requires more advanced hardware.
How to Use
- Install Dependencies: Requires Docker, Docker Compose, and other tools.
- Obtain API Keys: NVIDIA API Catalog and ElevenLabs API keys are required.
- Clone the Repository: Clone NVIDIA-AI-Blueprints/pdf-to-podcast from GitHub.
- Set Environment Variables: Configure API keys and other environment variables.
- Start Services: Use Docker Compose to start all microservices.
- Generate Audio: Use the command-line tool to specify a PDF file and generate audio content.
Application Scenarios
- Corporate Training and Policy Interpretation: Convert training manuals into audio podcasts for on-the-go learning.
- Technical and R&D Briefings: Convert research reports into audio content for easy access.
- Customer Service and Hotel Management: Convert service guides into conversational podcasts for skill practice.
- Medical and Emergency Preparedness: Convert medical protocols into audio content for emergency training.
