brh)This datasheet is for cv-corpus-27.0-2026-09-11 of the Mozilla Common Voice Scripted Speech dataset for Brahui [براہوئی - brh]. The dataset contains 5095 clips representing 9.93 hours of recorded speech (9.91 hours validated) from 18 speakers, recorded from a text corpus of 3,095 sentences.
Brahui is a dravidian language spoken primarily in Central and western Balochistan, Pakistan, with smaller communities in Afghanistan and Iran. Despite being geographically isolated from other Dravidian languages, Brahui has retained its distinct linguistics identity for centuries. It is spoken by around 2.8 million people and coexists with surrounding languages such as Balochi, Pashtu and Persian, which has influenced its vocabulary and structure. The language is traditionally oral, though it has been written using the Arabic scripts in modern times. Brahui holds historical significances and contributes to the rich linguistic diversity of the region. The language has three main dialects: Sarawani, Jalawani and Rakhshani, with Sarawani being the standard dialect.

There follows a randomly selected sample of five sentences from the corpus.
The corpus originates from a Brahui book. Sentences and short texts were created from the book and then spoken by native speakers for recording. Thus, the primary source is written Brahui material adapted into spoken form.

General
The original Brahui book was segmented into smaller sentences and short texts. These were distributed to native speakers, who recorded themselves reading the material.
Further post-processing may include verifying the alignment between text and audio, checking for transcription errors, and standardizing the text format.
Each row of a tsv file represents a single audio clip, and contains the following information:
