WhisperBot
Welcome to WhisperBot. WhisperBot builds upon the capabilities of the WhisperLive by integrating Mistral, a Large Language Model (LLM), on top of the real-time speech-to-text pipeline. WhisperLive relies on OpenAI Whisper, a powerful automatic speech recognition (ASR) system. Both Mistral and Whisper are optimized to run efficiently as TensorRT engines, maximizing performance and real-time processing capabilities.
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 Mistral and Whisper are optimized to run as TensorRT engines, ensuring high-performance and low-latency processing.
Prerequisites
Install TensorRT-LLM to build Whisper and Mistral TensorRT engines. The README builds a docker image for TensorRT-LLM. Instead of building a docker image, we can also refer to the README and the Dockerfile.multi to install the required packages in the base pytroch docker image. Just make sure to use the correct base image as mentioned in the dockerfile and everything should go nice and smooth.
Build Whisper TensorRT Engine
- Change working dir to the whisper example dir in TensorRT-LLM.
cd TensorRT-LLM/examples/whisper
- Currently, by default TensorRT-LLM only supports
large-v2
andlarge-v3
. In this repo, we usesmall.en
. - Download the required assets.
wget --directory-prefix=assets assets/mel_filters.npz https://raw.githubusercontent.com/openai/whisper/main/whisper/assets/mel_filters.npz
# small.en model
wget --directory-prefix=assets https://openaipublic.azureedge.net/main/whisper/models/f953ad0fd29cacd07d5a9eda5624af0f6bcf2258be67c92b79389873d91e0872/small.en.pt
- Edit
build.py
to supportsmall.en
. In order to do that, add"small.en"
as an item in the listchoices
. - Build
small.en
TensorRT engine.
pip install -r requirements.txt
python3 build.py --output_dir whisper_small_en --use_gpt_attention_plugin --use_gemm_plugin --use_layernorm_plugin --use_bert_attention_plugin --model_name small.en
Build Mistral TensorRT Engine
- Change working dir to llama example dir in TensorRT-LLM folder.
cd TensorRT-LLM/examples/llama
- Convert Mistral to
fp16
TensorRT engine.
python build.py --model_dir teknium/OpenHermes-2.5-Mistral-7B \
--dtype float16 \
--remove_input_padding \
--use_gpt_attention_plugin float16 \
--enable_context_fmha \
--use_gemm_plugin float16 \
--output_dir ./tmp/mistral/7B/trt_engines/fp16/1-gpu/ \
--max_input_len 5000
--max_batch_size 1
Run WhisperBot
- Clone this repo and install requirements.
git clone https://github.com/collabora/WhisperBot.git
cd WhisperBot
apt update
apt install ffmpeg portaudio19-dev -y
pip install -r requirements.txt
- Take the folder path for Whisper TensorRT model, folder_path and tokenizer_path for Mistral TensorRT from the build phase. If a huggingface model is used to build mistral then just use the huggingface repo name as the tokenizer path.
python3 main.py --whisper_tensorrt_path /root/TensorRT-LLM/examples/whisper/whisper_small_en \
--mistral_tensorrt_path /root/TensorRT-LLM/examples/llama/tmp/mistral/7B/trt_engines/fp16/1-gpu/ \
--mistral_tokenizer_path teknium/OpenHermes-2.5-Mistral-7B
- Use the
WhisperBot/client.py
script to run on the client side.
