Zinza Speech to Text: Preserving a Tanzanian Language with AI

Zinza (Oluzinza) is a Bantu language spoken by around 200,000 people in northwestern Tanzania, particularly in the regions surrounding Mwanza and Bukoba. As a language with deep roots in the oral culture of the Lake Victoria area, Zinza faces the risk of digital marginalization. Accurate speech to text technology offers a way to document, teach, and share the language in written form.

Where Is Zinza Spoken?

Zinza is primarily spoken in the following areas:

• Mwanza Region: Especially on the islands and shores of Lake Victoria's southern part.
• Kagera Region: Around Bukoba and along the border with Uganda.
• Nearby communities: Some Zinza speakers live in urban centers like Mwanza city, often alongside Swahili speakers.

The language belongs to the Bantu family (Niger-Congo) and is closely related to Haya, Kerebe, and Sukuma. It has several dialects, including Standard Zinza, Kerebe-influenced Zinza, and Bukoba Zinza, each with slight variations in vocabulary and pronunciation.

Why Accurate Zinza Transcription Matters

Transcribing Zinza audio is essential for several reasons:

• Cultural preservation: Many Zinza folktales, proverbs, and historical narratives are only available as audio recordings. Converting them to text ensures they survive for future generations.
• Education: Schools in Zinza-speaking areas can use transcribed materials to teach literacy in the mother tongue.
• Media accessibility: Local radio and video content can be subtitled in Zinza, making it accessible to deaf viewers and second-language learners.
• Research: Linguists and anthropologists need accurate transcripts to study Zinza grammar, phonology, and oral literature.

Challenges in Zinza Speech Recognition

Building ASR for Zinza comes with unique hurdles:

• Tone: Zinza is a tonal language. For example, the word okuhinda can mean 'to defeat' (high tone on hi) or 'to hide' (low tone on hi). Speechyou's model is trained to distinguish these tonal patterns.
• Vowel length: Short and long vowels are phonemic. Okuta (to throw) differs from okuta (to be scarce) by vowel length.
• Limited data: With only a few hundred thousand speakers, there is little digital text or audio available for training. Speechyou uses transfer learning from related Bantu languages to overcome this.
• Code-switching: Zinza speakers frequently mix Swahili words into their speech. The model includes a combined vocabulary to handle this naturally.

Use Cases for Zinza Speech to Text

• Oral history projects: Transcribe interviews with elders to document traditional knowledge.
• Podcast production: Convert Zinza-language podcasts into text for show notes and searchability.
• Subtitle generation: Add Zinza subtitles to educational videos on YouTube or local TV.
• Community meetings: Provide live or post-meeting transcripts for transparency and record-keeping.
• Language learning: Create written exercises from spoken dialogues.
• Accessibility: Enable deaf Zinza speakers to follow audio content via text.
