whisper-live 0.0.6

A nearly-live implementation of OpenAI's Whisper.

whisper-live

A nearly-live implementation of OpenAI's Whisper.

This project is a real-time transcription application that uses the OpenAI Whisper model to convert speech input into text output. It can be used to transcribe both live audio input from microphone and pre-recorded audio files.

Unlike traditional speech recognition systems that rely on continuous audio streaming, we use voice activity detection (VAD) to detect the presence of speech and only send the audio data to whisper when speech is detected. This helps to reduce the amount of data sent to the whisper model and improves the accuracy of the transcription output.

Installation

• Install PyAudio and ffmpeg

 bash setup.sh

• Install whisper-live from pip

 pip install whisper-live

Getting Started

• Run the server

 from whisper_live.server import TranscriptionServer
 server = TranscriptionServer()
 server.run("0.0.0.0", 9090)

• On the client side

  • To transcribe an audio file:

    from whisper_live.client import TranscriptionClient
    client = TranscriptionClient("localhost", 9090, multilingual=True, language="hi", translate=True)
    client(audio_file_path)
  

  This command transcribes the specified audio file (audio.wav) using the Whisper model. It connects to the server running on localhost at port 9090. It also enables the multilingual feature, allowing transcription in multiple languages. The language option specifies the target language for transcription, in this case, Hindi ("hi"). The translate option should be set to True if we want to translate from the source language to English and False if we want to transcribe in the source language.

  • To transcribe from microphone:

    from whisper_live.client import TranscriptionClient
    client = TranscriptionClient(host, port, multilingual=True, language="hi", translate=True)
    client()
  

  This command captures audio from the microphone and sends it to the server for transcription. It uses the same options as the previous command, enabling the multilingual feature and specifying the target language and task.

Transcribe audio from browser

• Run the server

 from whisper_live.server import TranscriptionServer
 server = TranscriptionServer()
 server.run("0.0.0.0", 9090)

This would start the websocket server on port 9090.

Chrome Extension

• Refer to Audio-Transcription-Chrome to use Chrome extension.

Firefox Extension

• Refer to Audio-Transcription-Firefox to use Mozilla Firefox extension.

Whisper Live Server in Docker

• GPU

 docker build . -t whisper-live -f docker/Dockerfile.gpu
 docker run -it --gpus all -p 9090:9090 whisper-live:latest

• CPU

 docker build . -t whisper-live -f docker/Dockerfile.cpu
 docker run -it -p 9090:9090 whisper-live:latest

Note: By default we use "small" model size. To build docker image for a different model size, change the size in server.py and then build the docker image.

Future Work

• Add translation to other languages on top of transcription.
• TensorRT backend for Whisper.
