Plateforme TAL (PTAL)

Speech and Language Processing Platform

PTAL

PTAL (pronounced "petal") is a collection of tools for speech and language processing. The name "PTAL" stands for "Plateforme de Traitement Automatique des Langues" which roughly translates to "Automatic Languages Processing Platform" in English.

Overview

PTAL is implemented in Julia, a language made for scientific programming. If you are unfamiliar with it, start by installing it and take a look at the documentation.

PTAL is organized into multiple independent tools hosted on public git repositories accessible here. Each tool is dedicated to a particular task (data loading, computing spectral representation, aligning speech, etc) and needs to be installed separately through PTAL's registry.

Tools

Datasets

SpeechDatasets.jl

Convenient and unified way to load a speech dataset. It can then be harnessed with other PTAL tools.
