Mojave Speech to Text: Revitalizing a Native American Language

Introduction to Mojave

Mojave (also spelled Mohave) is a Yuman language spoken by the Mojave people, who have lived along the Colorado River in present-day Arizona and California for centuries. The language is critically endangered, with estimates of fluent speakers ranging from a few dozen to under 100. Most speakers are elders, and younger generations are working to reclaim their ancestral tongue through immersion programs and digital tools.

Mojave belongs to the River branch of the Yuman language family, which also includes Quechan, Maricopa, and Kumeyaay. Its writing system uses a Latin-based orthography developed by linguists and community members. The language has a rich oral tradition, including creation stories, songs, and ceremonial speeches that are vital to cultural identity.

Why Accurate Speech to Text Matters for Mojave

• Documentation: Transcribing audio from elders preserves knowledge that might otherwise be lost.
• Education: Students can read along with spoken lessons to improve literacy.
• Accessibility: Subtitles make Mojave videos accessible to the deaf and hard-of-hearing.
• Research: Linguists can analyze transcribed texts for grammatical patterns.

Accurate speech-to-text for Mojave requires handling its distinctive phonology. Vowel length is phonemic: /a/ vs /a:/ changes meaning. For example, 'ava' (water) versus 'aava' (to drink). Pitch accent also plays a role, though it is less studied. Consonant clusters like /kʷ/ and /t͡ʃ/ are common.

Challenges in Mojave Transcription

Generic ASR models fail on Mojave because they lack training data and cannot handle the language's specific sounds. Speechyou overcomes this with a custom model trained on Mojave speech samples, including recordings from multiple dialects. The model uses transfer learning from related Yuman languages to improve robustness.

Background noise is a common issue in field recordings. Speechyou includes noise suppression and speaker diarization to separate voices. This is especially useful for group interviews where multiple speakers contribute.

Use Cases in Practice

Preserving Oral Histories

Elders hold invaluable knowledge about traditional plant use, history, and ceremonies. Transcribing these recordings creates a permanent written record. With Speechyou, you can upload hours of audio and receive text in minutes. The transcript can be edited and shared with the community.

Subtitle Creation

Mojave-language videos on YouTube or social media can reach wider audiences when subtitled. Speechyou generates SRT and VTT files that work with any video platform. This helps learners follow along and non-speakers understand the content.

Classroom Support

Language teachers can transcribe their lessons to provide reading materials. Students can review transcripts to reinforce vocabulary and grammar. Speechyou's high accuracy reduces the need for manual correction.

How Speechyou Helps

Speechyou is the only major speech-to-text service that supports Mojave. While competitors like Google Speech-to-Text and Whisper ignore the language, Speechyou offers a dedicated model with:

• Unlimited transcription in the Solo plan
• Support for long audio files (up to 2 hours)
• Export to SRT, VTT, and plain text
