- Common Voice 26.0 access update: We have received a report that the Common Voice 26.0 release configured for LRAC 2.0 may no longer be available through the previous Mozilla Data Collective access flow. We are checking this with Mozilla. For now, the prepare function will print a warning and continue without Common Voice when MDC cannot provide the configured release. Common Voice 26.0 remains an allowed dataset. Please do not replace it with an unapproved dataset. We will provide an update as we learn more.
