Usage Restrictions

There are some participants who did not sign the additional consent form authorizing release of audio information, mainly because this procedure was developed after their participation was complete and we were unable to contact them for post-hoc consent. If any researcher analyzes the available recordings, has promising results, and would like to access the rest of the data, we can find a way to make that happen without depositing the data in the main Aphasiabank database. The data may be analyzed and results reported in aggregate. In general, the raw audio recordings may not be played for a broad audience in public presentations, conferences, or web pages. However, some participants did specifically consent to such educational use – any proposed use should be cleared with us first to ensure that such consent was obtained.
