Preserving the Voice of the Kissi People: AI-Powered Speech-to-Text

Introduction to the Kissi Language

The Kissi language (also spelled Kisi) is a vibrant Mande language spoken by around 1.5 million people in the forested highlands of Guinea, with diaspora communities in Sierra Leone and Liberia. It is a tonal language, meaning that pitch contours differentiate word meanings. The Latin script has been adapted for writing Kissi, with a standard orthography used in local schools and literature. Despite its cultural significance, Kissi is considered a low-resource language in the field of natural language processing, lacking the large datasets that power mainstream speech recognition systems.

Why Accurate Speech-to-Text Matters for Kissi

Accurate transcription of Kissi audio opens up numerous possibilities:

• Cultural Preservation: Oral traditions, including folktales, proverbs, and historical accounts, can be converted into searchable text, preventing loss over time.
• Education: Teachers can transcribe lessons and create subtitles for instructional videos, improving literacy and comprehension among Kissi-speaking students.
• Media Accessibility: Community radio broadcasts and local YouTube channels can add Kissi subtitles, making content accessible to deaf or hard-of-hearing viewers.
• Linguistic Research: Academics studying Kissi phonology, syntax, and dialect variation can quickly transcribe field recordings, saving hours of manual work.

Challenges in Transcribing Kissi

Developing robust speech-to-text for Kissi comes with unique hurdles:

1. Tonal Contours: As a tonal language with three levels (high, mid, low), any ASR system must accurately capture pitch. Misrecognizing a tone can completely change the meaning of a sentence.
2. Data Scarcity: There are very few public corpora of transcribed Kissi speech. Most existing recordings are in audio-only format without corresponding text.
3. Dialectal Diversity: Southern Kisi (kss) and Northern Kisi (ksq) differ in vowel quality and some vocabulary. A model trained on one dialect may perform poorly on the other.
4. Code-Switching: Many Kissi speakers mix French or English words into their speech, especially in urban settings, which can confuse models not trained on multilingual input.

How Speechyou Overcomes These Challenges

Speechyou is built from the ground up to handle low-resource languages like Kissi. Our approach includes:

• Tone-Aware Training: We use a combination of acoustic features (pitch tracking) and tonal labels to teach the model to distinguish high, mid, and low tones.
• Dialect-Specific Models: Users can select either Southern Kisi or Northern Kisi mode, ensuring optimal accuracy for their region.
• Continuous Learning: When users correct transcription errors, the corrected data is used to retrain the model, gradually improving its performance.
• Multilingual Support: The system can handle code-switching and is trained to recognize common French and English loanwords within Kissi contexts.

Use Cases in Action

Oral History Preservation

Elders in Kissi villages hold invaluable knowledge about traditional medicine, genealogy, and local history. With Speechyou, researchers can record interviews and instantly obtain transcripts in the Latin script. These transcripts can be stored in digital archives and shared with younger generations.

Community Radio

Radio stations like "Radio Nzérékoré" broadcast news and music in Kissi. By generating subtitles automatically, stations can reach a broader audience, including those who are deaf or hard of hearing. The SRT files can be embedded in video streams or posted online.

Educational Materials

Local NGOs working on literacy projects can upload audio of Kissi-language lessons and receive text versions. These texts can be used to create reading materials, glossary lists, and even interactive exercises.
