 The SUMM-RE dataset is a corpus of meeting-style conversations in French created for the purpose of the SUMM-RE project (ANR-20-CE23-0017). 
 
 Each conversation lasts roughly 20 minutes. The number of conversations contained in each split is as follows:
-- `dev`: 36 (x ~20 minutes = ~12 hours)
 - `train`: 210 (x ~20 minutes = ~70 hours)
+- `dev`: 36 (x ~20 minutes = ~12 hours)
 - `test`: 37 (x ~20 minutes = ~12.3 hours)
 
 
-Each conversation contains 3-4 speakers (and in rare cases, 2) and each participant has an individual microphone and associated .wav file, giving rise to the following number of files for each split:

-## Uses
-
-### Direct Use
-
-The `dev` and `test` splits of SUMM-RE can be used for the evaluation of automatic speech recognition models and voice activity detection for conversational, spoken French. All splits can be used for the training of large language models. 
-
-### Out-of-Scope Use
-
-Due to its size, the corpus is not suitable for training of automatic speech recognition or voice activity detection models.
