Audiobook alignment for Indigenous languages!
This library is an end-to-end audio/text aligner. It is meant to be used together with the ReadAlong-Web-Component to interactively visualize the alignment.
See also: ReadAlong-Studio documentation.
The concept is a web application with a series of stages of processing, which ultimately leads to a time-aligned audiobook - i.e. a package of:
- ReadAlong XML file describing text
- Audio file (WAV or MP3)
Which can be loaded using the read-along web component. See also Studio Output Realizations.
Optionally a book can be generated as a standalone HTML page, XHTML, Praat TextGrid, ELAN Eaf file, as well as WebVTT or SRT subitle formats.
- (optional) Pre-segment inputs, consisting of:
- Single audio file
- Text with page markings (assume paragraph breaks = pages)
- Input pages: each page consists of
- Image file
- Audio file
- Text
- Run alignment
- View output and download components
Before you can install the ReadAlong Studio, you will need to install these dependencies:
- Python, version 3.8 or higher,
- FFmpeg,
- a C compiler,
- Git (optional, needed to get the current development version).
First install Homebrew, then use it to install FFmpeg with brew install ffmpeg.
The compiler should already be on your machine.
Consider Xcode for your XML and text file editor.
If FFmpeg is not already installed, <your package manager> install ffmpeg should add it.
The compiler should already be there, but run <your package manager> install gcc if not.
The conda package manager can install Python 3 and the required compiler automatically for you,
and simplifies ffmpeg and git installation. We recommend this solution.
If the Anaconda Terms of Service are compatible with your organization, you can use Miniconda3: download and run the latest "Miniconda3 Windows 64-bit" installer from https://docs.conda.io/en/latest/miniconda.html.
Fully open-source alternative, free for all organizations: Miniforge3. Download and run the latest "Miniforge3-Windows-x86_64" installer from https://github.com/conda-forge/miniforge.
Either way, you can accept all the default options suggested by the installer.
Launch an Anaconda Prompt or a Miniforge Prompt (this should be available from your Start Menu after installation) and run:
conda install ffmpeg
conda install git
You can then run the pip install and git commands below, and use readalongs, all from the Anaconda or Miniforge Prompt.
If you know what you're doing, you can install the dependencies directly on your machine:
- Install Python3 for Windows.
- Install FFmpeg builds for Windows (alternative instructions).
- Install Visual Studio Build Tools (search for "Build Tools", select C++ when prompted).
- Install Git for Windows (optional).
To install the latest version of readalongs published to PyPI, you can run a standard pip
installation: pip install readalongs. Be warned, however, that this project is still very active so the published version could be out-of-date. Consider installing the current development version instead.
To install the current development version, clone the repo and pip install it locally:
$ git clone https://github.com/ReadAlongs/Studio.git
$ cd Studio
$ pip install -e .Run readalongs -h to confirm that installation was successful.
If you installed the current development version with Git, you can also run the full test suite:
cd Studio/test
python run.py dev
And you can download our open samples on GitHub to run your first alignments.
ReadAlong-Studio can be used either through the command line, a distributed web application or Docker.
This page lists only the most basic commands.
For more information about how the command line interface works:
- Consult the CLI User Guide.
- Consult the CLI Reference.
- Invoke any CLI command with
-hor--helpfor usage information. e.g.,readalongs --help,readalongs align --help.
Basic alignment is done with the following command.
readalongs align TEXTFILE WAVFILE OUTPUTNAME
This page lists only the most basic commands.
For more information about how the command line interface works consult the interactive API Documentation.
For information on spinning up your own dev Web API server locally, have a look at web_api.py, but briefly, if you are running it locally for development, use:
DEVELOPMENT=1 uvicorn readalongs.web_api:web_api_app --reload
or
./run-web-api.sh
Note that the production command line for the Web API is defined in Procfile and documented in web_api.py.
To query a list of available languages in the ReadAlong Studio API, send a GET request to https://readalongs-studio.herokuapp.com/api/v1/langs
This endpoint is a remote procedural call that assembles the data needed to build a readalong using the JavaScript-based SoundSwallower decoder. It is an endpoint that accepts POST requests with either plaintext or XML input. Please see the documentation for more information.
The ReadAlong-Studio web interface is available at https://readalong-studio.mothertongues.org/ and the source code is available here: https://github.com/ReadAlongs/Web-Component
If you are having trouble installing the package, you can also clone the repo and run the studio using Docker.
Working with in a Docker container has the advantage that no matter what your OS is, and what you have installed or configured, you will run on the standard ReadAlong-Studio configuration.
To build the Docker image, run:
docker build . --tag=readalong-studio
To run the Flask web app in a Docker container using that image:
docker run -p 5000:5000 -it readalong-studio
To run the Flask web app with real-time update:
docker run -p 5000:5000 -it -v $(pwd):/opt/readalong-studio readalong-studio
Then you should be able to visit http://localhost:5000/.
To run the interactive shell with real-time update:
docker run -p 5000:5000 -it -v $(pwd):/opt/readalong-studio readalong-studio sh
To run an interactive bash shell, using your local user inside Docker:
docker run -p 5000:5000 -it -v $(pwd):/opt/readalong-studio -u $(id -u):$(id -g) readalong-studio bash

We build on an existing Python library for zero-shot multilingual textspeech alignment (Littell et al., 2022), extend it by exposing its functionality through a RESTful API, and rewrite the underlying speech recognition engine to run in the browser. The ReadAlong Studio Web App is open-source, user-friendly, prioritizes privacy and data sovereignty, allows for a variety of standard export formats, and is designed to work for the majority of the world{'}s languages.",
