# Whisper Tiny - Toki Pona - Synthetic Test 1
|
| 20 |
+
|
| 21 |
+
This experimental model is a fine-tuned version of [openai/whisper-tiny](https://huggingface.co/openai/whisper-tiny) on a mix of custom synthetic data and Common Voice 23.0 - Toki Pona.
|
| 22 |
+
|
| 23 |
+
The evaluation set contains synthetic data, as opposed to the `whisper-small`-based model, so evaluation values are not provided.
|
| 24 |
+
|
| 25 |
+
## Model description
|
| 26 |
+
|
| 27 |
+
This is an experimental model trained for speech recognition for Toki Pona.
|
| 28 |
+
|
| 29 |
+
As the original model is multilingual with explicit language specification tokens, we have replaced the Czech (`cs`) language with Toki Pona, as we have determined it to have the closest phonetics.
|
| 30 |
+
|
| 31 |
+
The model's performance for other languages may have been at least partially preserved, but no testing has been done for other languages.
|
| 32 |
+
|
| 33 |
+
