Metadata

Tetelancingo Nahuatl Corpus

A corpus of audio and annotated transcriptions of Western Sierra Puebla Nahuatl, an endangered variety of Nahuatl spoken in Puebla, Mexico. The corpus contains recorded monologues and dialogues from a total of 5 speakers from a community in Zacatlán de las Manzanas. Each recording is associated with (1) an original transcription written in a "spontaneous orthography," (2) a normalized version written in a local written standard from San Miguel Tenango, (3) an unedited Spanish translation, and (4) word-level language tags.

For more information about the dataset and some preliminary experiments, see the paper Ihquin tlahtouah in Tetelahtzincocah: An annotated, multi-purpose audio and text corpus of Western Sierra Puebla Nahuatl

    abstract = "The development of digital linguistic resources is essential for enhancing the inclusion of indigenous and marginalized languages in the digital domain. Indigenous languages of Mexico, despite representing vast typological diversity and millions of speakers, have largely been overlooked in NLP until recently. In this paper, we present a corpus of audio and annotated transcriptions of Western Sierra Puebla Nahuatl, an endangered variety of Nahuatl spoken in Puebla, Mexico. The data made available in this corpus are useful for ASR, spelling normalization, and word-level language identification. We detail the corpus-creation process, and describe experiments to report benchmark results for each of these important NLP tasks. The corpus audio and text is made freely available."
