Sena Speech to Text: Transcribe Chisena Audio with AI

Sena (Chisena) is a Bantu language spoken by an estimated 1.5 million people across Mozambique, Malawi, and Zimbabwe. It belongs to the Niger-Congo family and is part of the larger Sena-Tumbuka subgroup. In Mozambique, it is primarily spoken in the provinces of Sofala, Manica, and Tete, while in Malawi it is found in the southern districts of Nsanje and Chikwawa. Despite its significant speaker base, Sena has limited digital resources, making accurate speech-to-text transcription a challenge until now.

Why Accurate Sena Transcription Matters

For Sena speakers, access to transcription tools means more than convenience. It enables:

• Preservation of oral traditions: Sena has a rich heritage of storytelling, proverbs, and songs. Transcribing these recordings helps preserve them for future generations.
• Education: Teachers can convert spoken lessons into written texts for students, improving literacy in Chisena.
• Media and journalism: Local radio stations and online content creators can produce subtitles and transcripts for wider reach.
• Accessibility: Deaf or hard-of-hearing Sena speakers can access audio content through text transcripts.

Without a dedicated Sena speech-to-text tool, these tasks were either impossible or required expensive human transcription. Speechyou changes that.

Transcription Challenges Specific to Sena

Sena presents several challenges for automatic speech recognition:

• Tonal distinctions: Like many Bantu languages, Sena uses tone to differentiate words. For example, 'kutema' (to cut) vs. 'kutema' (to be sour) differ only in pitch. Most ASR systems ignore tone, leading to errors.
• Vowel length: Long and short vowels are phonemic, so 'kula' (to grow) vs. 'kuula' (to buy) must be distinguished.
• Prenasalized consonants: Sounds like 'nd', 'mb', and 'ng' are common and can be misheard as separate consonants.
• Dialectal variation: Sena dialects vary significantly. Our model includes data from the main dialect groups.

Speechyou's AI is trained to handle these features, achieving over 95% accuracy on clear audio.
