| Challenge: | Low-resource languages suffer from a vicious circle: data is needed to build tools, but available text is scarce. |
| Approach: | They propose to use a grammar-based system to generate Spanish text and syntactically transfer it to Guarani to boost its performance. |
| Outcome: | The proposed system outperforms existing models by pretraining models with synthetic text. |
