Decision brief

Aeneas is a Python library and CLI toolset for audio-text synchronization specifically designed to address forced alignment needs.

Good fit when

When you need precise alignment of text with spoken words in audio files, as Aeneas excels at forced alignment tasks
If your project requires integration into existing Python workflows that demand high performance and accuracy

Avoid when

Avoid if your system cannot meet the minimum requirements for Python versions below 3.5 or lacks essential dependencies such as FFmpeg or eSpeak
Do not use when a more lightweight solution suffices, as Aeneas includes comprehensive but resource-intensive C/C++ extensions

Requirements:: Min 4 GB RAM; Python 2.7 or later; FFmpeg; eSpeak; Numpy, BeautifulSoup4, lxml as Python packages

System Requirements, Supported Platforms and Installation

System Requirements

a reasonably recent machine (recommended 4 GB RAM, 2 GHz 64bit CPU)
Python 2.7 (Linux, OS X, Windows) or 3.5 or later (Linux, OS X)
FFmpeg
eSpeak
Python packages BeautifulSoup4, lxml, and numpy
Python headers to compile the Python C/C++ extensions (optional but strongly recommended)
A shell supporting UTF-8 (optional but strongly recommended)

Installation

All-in-one installers are available for Mac OS X and Windows, and a Bash script for deb-based Linux distributions (Debian, Ubuntu) is provided in this repository. It is also possible to download a VirtualBox+Vagrant virtual machine. Please see the INSTALL file for detailed, step-by-step installation procedures for different operating systems.

The generic OS-independent procedure is simple:

Install Python (2.7.x preferred), FFmpeg, and eSpeak
Make sure the following executables can be called from your shell: espeak, ffmpeg, ffprobe, pip, and python
First install numpy with pip and then aeneas (this order is important):
```
pip install numpy
pip install aeneas
```
To check whether you installed aeneas correctly, run:
```
 python -m aeneas.diagnostics
```
