donateacry-corpus

An infant cry audio corpus that has been built through the Donate-a-cry campaign (no longer active)

Source of these files

This repository contains user-uploaded audio samples in their original, unmodified, unchecked form. The audio samples were uploaded using the Donate-a-cry mobile applications for Android and iOS.

Using the files

The database is published under the ODbL, see below. If you work with the corpus in any way, please drop us a line at hello@newparentsapps.com

File naming convention

The audio files should contain baby cry samples, with the corresponding tagging information encoded in the filenames. The samples were tagged by the contributors themselves. So here's how to parse the filenames.

iOS:
0D1AD73E-4C5E-45F3-85C4-9A3CB71E8856-1430742197-1.0-m-04-hu.caf
app instance uuid (36 chars)-unix epoch timestamp-app version-gender-age-reason

So, the above translates to:

• the sample was recorded with the app instance having the unique id 0D1AD73E-4C5E-45F3-85C4-9A3CB71E8856. These ids are generated upon installation, so they identify an installed instance, not a device or a user
• the recording was made at 1430742197 (unix time epoch) , which translates to Mon, 04 May 2015 12:23:17 GMT
• version 1.0 of the mobile app was used
• the user tagged the recording to be of a boy
• the baby is 0-4 weeks old according to the user
• the suspected reason of the cry is hunger

Android:
0c8f14a9-6999-485b-97a2-913c1cbf099c-1431028888092-1.7-m-26-sc.3gp
The structure is the same with the exception that the unix epoch timestamp is in milliseconds
