Introduction

Whisper is a general-purpose speech recognition model. It is trained on a large dataset of diverse audio and is also a multi-task model that can perform multilingual speech recognition as well as speech translation and language identification.

Whisper model trained by OpenAI whisper https://github.com/openai/whisper

Usage

1. Installation

see installation.

You can choose one way from easy, meduim and hard to install paddlespeech.

2. Prepare Input File

The input of this demo should be a WAV file(.wav), and the sample rate must be the same as the model.

Here are sample files for this demo that can be downloaded:

wget -c https://paddlespeech.bj.bcebos.com/PaddleAudio/zh.wav

3. Usage

• Command Line(Recommended)

  # to recognize text 
  paddlespeech whisper --task transcribe --input ./zh.wav
  
  # to change model English-Only base size model
  paddlespeech whisper --lang en --size base --task transcribe  --input ./en.wav
  
  # to recognize text and translate to English
  paddlespeech whisper --task translate --input ./zh.wav
  
  

  Usage:

  paddlespeech whisper --help
  

  Arguments:

  • input(required): Audio file to recognize.
  • model: Model type of asr task. Default: whisper-large.
  • task: Output type. Default: transcribe.
  • lang: Model language. Default: ``. Use en to choice English-only model. Now [medium,base,small,tiny] size can support English-only.
  • size: Model size for decode. Defalut: large. Now can support [large,medium,base,small,tiny].
  • language: Set decode language. Default: None. Forcibly set the recognized language, which is determined by the model itself by default.
  • sample_rate: Sample rate of the model. Default: 16000. Other sampling rates are not supported now.
  • config: Config of asr task. Use pretrained model when it is None. Default: None.
  • ckpt_path: Model checkpoint. Use pretrained model when it is None. Default: None.
  • yes: No additional parameters required. Once set this parameter, it means accepting the request of the program by default, which includes transforming the audio sample rate. Default: False.
  • device: Choose device to execute model inference. Default: default device of paddlepaddle in current environment.
  • verbose: Show the log information.

• Python API
