wav2letter++ is a powerful automatic speech recognition (ASR) tool that has recently been consolidated into the Flashlight framework. Its recipes offer a robust way to reproduce several research papers and leverage pre-trained models. Let’s walk through the steps to get started with this tool!

Understanding wav2letter++

Imagine you are a chef trying to recreate classic dishes from various cuisines. Each recipe represents a research paper that provides a unique way to approach speech recognition. Just like you need specific ingredients and tools to create a dish, in wav2letter++, you’ll require Flashlight and certain code recipes to reproduce these research achievements.

Prerequisites: What You Will Need

• A working installation of Flashlight v0.3.2
• Knowledge of basic command line operations
• Access to the internet for downloading packages and models

Step-by-Step Guide to Building and Running Recipes

Follow these steps to prepare and run your experiments:

1. Install Flashlight

First, you need to install Flashlight. Clone the repository and build it using the following commands:

mkdir build
cd build
cmake ..
make -j8

2. Handle Non-Standard Installation Paths

If you installed Flashlight or ArrayFire in a non-standard path, specify their locations during the CMake configuration:

cmake -Dflashlight_DIR=[PREFIX]/usr/share/flashlight/cmake -DArrayFire_DIR=[PREFIX]/usr/share/ArrayFire

3. Prepare Data

Data preparation is crucial for training and evaluation. You can find relevant scripts and data in the data directory.

4. Reproduce Research Papers

With everything in place, you can use the recipes provided in this repository to reproduce findings from various papers. These recipes are your culinary guides in the kitchen of machine learning!

Troubleshooting Tips

If you encounter any issues while building or running the recipes, consider these solutions:

• Ensure that you are using the correct Flashlight version, which must be v0.3.2.
• If CMake fails to find your installations, double-check that the paths provided are correct.
• For dependencies, ensure that ArrayFire is installed if it is required by Flashlight.
