What makes Hausa hard for speech recognition
Hausa is tonal and has long and short vowels, but standard spelling marks neither, so text alone doesn't tell a model how a word sounds. It also has implosive and ejective consonants and borrows heavily from Arabic and English.
Built for
- Automatic speech recognition (ASR / STT)
- Text-to-speech and voice synthesis prosody
- Voice agents and IVR for Nigeria
- Speaker diarization and turn-taking models
- Speech LLM and audio-understanding fine-tuning
