What makes Surinamese Dutch hard for speech recognition
Surinamese Dutch has its own pronunciation and vocabulary and lives alongside Sranan Tongo, Sarnami Hindustani, Javanese and English. Speakers switch between them in the same conversation, so a model trained only on Dutch from the Netherlands misses a lot.

- Automatic speech recognition (ASR / STT)
- Text-to-speech and voice synthesis prosody
- Voice agents and IVR for Suriname
