Koonzime Speech to Text: Preserving a Cameroonian Language with AI

Koonzime (also spelled Koonzime) is a Bantu language spoken primarily in the East Region of Cameroon, with some speakers across the border in the Republic of Congo. It is part of the Makaa-Njem language cluster and is closely related to Njem, Djem, and Bomwali. With an estimated 30,000 native speakers, Koonzime is considered a vulnerable language by UNESCO. Accurate speech-to-text technology can play a vital role in documenting, teaching, and revitalizing the language.

Why Accurate Transcription Matters for Koonzime

For minority languages like Koonzime, digital tools are essential for preservation. Oral histories, traditional songs, and everyday conversations can be transcribed and archived, creating a written record for future generations. Koonzime has a Latin-based orthography, but many speakers are more comfortable speaking than writing. Speechyou's Koonzime speech-to-text service bridges this gap, allowing anyone to convert spoken Koonzime into text instantly.

Specific Challenges in Transcribing Koonzime Audio

• Tone: Koonzime uses two phonemic tones (high and low). For example, the word /bà/ (low) means 'to be', while /bá/ (high) means 'to hit'. Without tone recognition, transcription would be ambiguous. Speechyou's AI processes pitch contours and outputs tone marks where the orthography supports them.
• Vowel harmony: Vowels must agree in advanced tongue root (ATR) status. This affects suffixes and verb extensions. The ASR must enforce harmony rules to produce grammatical text.
• Dialect diversity: Njem, Djem, and central Koonzime have lexical and phonological differences. Speechyou allows users to select their dialect, and the model adjusts its predictions accordingly.
• Limited data: Most commercial ASR systems ignore Koonzime entirely. Speechyou uses a custom-trained model built on a small but growing corpus, and user feedback continuously improves it.
