Data from the UltraSuite repository is available via the rsync command. All flags from this tools should be valid when syncing the UltraSuite repository.

Because the repository is quite large (380 GB), please make sure you have enough space on your disk. Alternatively, go through these instructions and download only a subset of the data for which you have space for.

Using rsync

rsync is a command-line tool that allows efficient and fast transfer and synchronisation of files across systems. This is usually pre-install on Linux or mac machines. These instructions assume you have the tool installed on your system, but do not assume a lot of experience with its usage.

If you are familiar with rsync, you can skip ahead and merely glance at the typical commands. All flags commonly used with the tool should be applicable to this scenario.

If you are not familiar with rsync, you should be aware that, if you have a version of the data on your disk, rsync will synchronise your local data with the latest version of UltraSuite. If there are changes to the UltraSuite repository, your data will be overwritten with those latest changes. A useful flag to use with the tool is --dry-run, which will simulate the synchronisation process.

Setting up

To get started, please create a directory on a hard drive where a large amount of space is available. Then, change your current directory onto that newly created one. On Linux or maxOS, this can be achieved by running:

mkdir UltraSuite
cd UltraSuite

Download a sample

Now that we have a place to store the data, we will download some sample data from the repository. This might be useful if you wish to get a small example to get familiar with the format of the data or test some code.

We first download a single utterance. This is a set of four files: a waveform (.wav), a text file with the prompt text and recording date time (.txt), the raw ultrasound data (ult), and a text file with parameters for the ultrasound data (.param). Running the following command should sync the first utterance from speaker 01M in the Ultrax Typically Developing (UXTD) data set.

rsync -av* .

The sample we've just downloaded should give you an idea of the type of data available in UltraSuite. Speaker 01M in the UXTD set has 121 utterances. You can download different samples by changing 001*to the corresponding utterance.

If you'd like, you can get all of the data for speaker 01M. This corresponds to 1.9GB! To do so, please run the following command

rsync -av .

Download a data set

You can download an entire data set by syncing its corresponding directory. For example, for the UXTD data set (82GB), you can run the following command:

sync -av .

The same command can be used to download /core-uxssd and /core-upx. Please be aware that each dataset can be quite large:

Dataset Size
/core-uxtd 82GB
/core-uxssd 110GB
/core-upx 191GB

The structure of each data set is identical and it follows the following pattern:


Please see the list of speakers of each of the datasets, if you are interested in downloading data from single speakers. To simulate the process, you can run rsync with the flag --dry-run and get an estimate for the amount of data.

Download label data

To download manual and automatically-generated labels for all three datasets (80MB), please run:

rsync -av .

You can get labels for each of the datasets by appending /uxtd, /uxssd, or /upxto the command above. There is also a documentation directory for the labels called /doc.

Download the entire repository

The following command illustrates how you can download the entire repository.

Warning: running the following command will download ~380GB of data!

rsync -av .
