Chopi Speech to Text: Preserving a Mozambican Language with AI

Chopi (Xichopi) is a Bantu language spoken by around one million people in southern Mozambique, mainly in the Inhambane Province. It is part of the Tsonga language group and has three main dialects: Central Chopi, Lenge, and Guambeta. Despite its rich oral tradition, Chopi is underrepresented in digital tools. Accurate speech-to-text for Chopi can transform how the language is used in media, education, and preservation.

Why Accurate Chopi Transcription Matters

Transcribing spoken Chopi is not just about converting audio to text. It helps preserve the language for future generations, supports bilingual education, and makes local content accessible. For example, a Chopi language radio program can be transcribed to create a searchable archive. Community meetings, sermons, and storytelling sessions can be documented and shared. Subtitling Chopi videos with SRT or VTT files also helps reach a wider audience, including those who speak Portuguese or other languages.

Challenges in Chopi Speech Recognition

Chopi is a tonal language, meaning that pitch distinguishes word meanings. For instance, the same syllable sequence can mean different things depending on tone. This requires ASR systems to be tone-aware. Additionally, the three dialects have different phonetic inventories and vocabulary. Most commercial transcription tools do not support Chopi at all, leaving speakers without a solution. Speechyou addresses these challenges by:

• Training on tonal data from native speakers
• Providing dialect selection (Chopi, Lenge, Guambeta)
• Using noise reduction for field recordings
• Offering speaker diarization for multi-speaker audio

Use Cases for Chopi Speech-to-Text

• Oral History Preservation: Record and transcribe stories from elders to create a digital archive of Chopi folklore and history.
• Local Media: Transcribe radio broadcasts, interviews, and news in Chopi for subtitling or archival purposes.
• Education: Convert Chopi language lessons and educational videos into text for classroom use.
• Accessibility: Generate subtitles for Chopi content on YouTube or social media, helping deaf or hard-of-hearing viewers.
• Research: Linguists can transcribe fieldwork recordings for analysis without manual effort.
• Community Events: Transcribe meetings, church services, and public announcements for record-keeping.
