| Challenge: | Afrispeech-Dialog is a benchmark dataset of 50 simulated medical and non-medical African-accented English conversations . a 10%+ performance degradation is found in ASR systems on long-form, accented speech . |
| Approach: | They propose to use a dataset to evaluate automatic speech recognition systems on African-accented conversations. |
| Outcome: | The proposed dataset compares state-of-the-art speech recognition systems on accented conversations with native accents and shows a 10%+ performance degradation. |

| Challenge: | Recent advances in multimodal and speech-native large language models have delivered impressive speech recognition, translation, understanding, and question-answering capabilities for high-resource languages. |
| Approach: | They propose to benchmark African languages and African-accented French, Arabic, and 100+ African English accents across 20 African languages. |
| Outcome: | The proposed model outperforms traditional speech transcription and translation models in African languages and non-native French or English accents. |
