whisper.cpp/tests/librispeech

LibriSpeech is a standard dataset for training and evaluating automatic speech recognition systems.

This directory contains a set of tools to evaluate the recognition performance of whisper.cpp on LibriSpeech corpus.

Quick Start

1. (Pre-requirement) Compile whisper-cli and prepare the Whisper model in ggml format.

   $ # Execute the commands below in the project root dir.
   $ cmake -B build
   $ cmake --build build --config Release
   $ ./models/download-ggml-model.sh tiny
   

   Consult whisper.cpp/README.md for more details.

2. Download the audio files from LibriSpeech project.

   $ make get-audio
   

3. Set up the environment to compute WER score.

   $ pip install -r requirements.txt
   

   For example, if you use virtualenv, you can set up it as follows:

   $ python3 -m venv venv
   $ . venv/bin/activate
   $ pip install -r requirements.txt
   

4. Run the benchmark test.

   $ make
   

How-to guides

How to change the inference parameters

Create eval.conf and override variables.

WHISPER_MODEL = large-v3-turbo
WHISPER_FLAGS = --no-prints --threads 8 --language en --output-txt

Check out eval.mk for more details.
