Each device was placed in the same location in the center of the room. The speaker read sentences five at a time, moving position each time. The positions were roughly assigned and can be best described as close-rear-left, far-front-left, far-front-right, close-rear-right (in order). The final paragraph was read in the same location as the last 5 sentences (close-rear-right).

#### Example of Usage
|
| 38 |
+
This data was used to measure microphone quality in the context of ASR. The metric used was WER from the output of `WhisperModel` from `faster_whisper`. The follow parameters were used:
|
| 39 |
+
```
|
| 40 |
+
whisper = WhisperModel(
|
| 41 |
+
model_size_or_path="deepdml/faster-whisper-large-v3-turbo-ct2",

+
device="cuda",

)
