This bundle contains the 13 Mozilla Common Voice Scripted Speech 26.0 locale releases specified in the official Cisco LRAC 2.0 Challenge 2026 data-preparation pipeline: ar, de, es, fa, fr, it, ja, pt, ru, sw, zh, zh-HK, and zh-TW. It contains the existing cv-corpus-26.0-2026-06-12 release and is a packaging of existing data, not a newly collected or annotated dataset. The bundle is intended to provide approved LRAC participants with a consistent access point while retaining the original Common Voice provenance, metadata, licensing, and usage restrictions.
