 ### Vocabulary Isolation

+The vocabulary in this dataset has very low overlap with existing Bambara ASR training corpora. To verify that, we have drawn two one-hour subsets from the two publicly available ASR dataset (at the time of compiling this report) by randomly selecting utterances and we observed the following word overlap figures:
 
-| Training corpus | Shared words | Unique to this benchmark |
+| Training corpus | Shared words | Overlap with this benchmark |
 |:---|:---|:---|
-| `RobotsMali/bam-asr-early` (1,622 words) | 297 | ~75% |
-| `RobotsMali/kunkado` | 319 | ~73% |

-Words like *yuruguyuruguli* (disorder/embezzlement) and *yamaruyasariya* (ordinance/regulation) are central to the constitutional register but virtually absent from conversational Bambara.
+So this benchmark features about 75% unique words when compared with equal sized samples of these two datasets, confirming how narrow the domain is. Words like *yuruguyuruguli* (disorder/embezzlement) and *yamaruyasariya* (ordinance/regulation) are central to the constitutional register but virtually absent from conversational Bambara.
