WhisperFusion

Seamless conversations with AI (with ultra-low latency)

Welcome to WhisperFusion. WhisperFusion builds upon the capabilities of the WhisperLive and WhisperSpeech by integrating Mistral, a Large Language Model (LLM), on top of the real-time speech-to-text pipeline. Both LLM and Whisper are optimized to run efficiently as TensorRT engines, maximizing performance and real-time processing capabilities. While WhiperSpeech is optimized with torch.compile.

Features

• Real-Time Speech-to-Text: Utilizes OpenAI WhisperLive to convert spoken language into text in real-time.

• Large Language Model Integration: Adds Mistral, a Large Language Model, to enhance the understanding and context of the transcribed text.

• TensorRT Optimization: Both LLM and Whisper are optimized to run as TensorRT engines, ensuring high-performance and low-latency processing.

• torch.compile: WhisperSpeech uses torch.compile to speed up inference which makes PyTorch code run faster by JIT-compiling PyTorch code into optimized kernels.

Hardware Requirements

• A GPU with at least 24GB of RAM
• For optimal latency, the GPU should have a similar FP16 (half) TFLOPS as the RTX 4090. Here are the hardware specifications for the RTX 4090.

The demo was run on a single RTX 4090 GPU. WhisperFusion uses the Nvidia TensorRT-LLM library for CUDA optimized versions of popular LLM models. TensorRT-LLM supports multiple GPUs, so it should be possible to run WhisperFusion for even better performance on multiple GPUs.

Getting Started

We provide a Docker Compose setup to streamline the deployment of the pre-built TensorRT-LLM docker container. This setup includes both Whisper and Phi converted to TensorRT engines, and the WhisperSpeech model is pre-downloaded to quickly start interacting with WhisperFusion. Additionally, we include a simple web server for the Web GUI.

• Build and Run with docker compose

  
  mkdir docker/scratch-space
  cp docker/scripts/build-* docker/scripts/run-whisperfusion.sh docker/scratch-space/

docker compose build export MODEL=Phi-3-mini-4k-instruct #Phi-3-mini-128k-instruct or phi-2, By default WhisperFusion uses phi-2 docker compose up

- Start Web GUI on `http://localhost:8000`
