# Whisper-medium-et
|
45 |
+
|
46 |
+
This is a Whisper-medium model [openai/whisper-medium](https://huggingface.co/openai/whisper-medium) finetuned on around 800 hours of diverse Estonian data.
|
47 |
+
|
48 |
+
## Model description
|
49 |
+
This is a general-purpose Estonian ASR model trained in the Lab of Language Technology at TalTech.
|
50 |
+
|
51 |
+
|
52 |
+
## Intended uses & limitations
|
53 |
+
|
54 |
+
This model is intended for general-purpose speech recognition, such as broadcast conversations, interviews, talks, etc.
|
55 |
+
|
56 |
+
## How to use
|
57 |
+
|
58 |
+
Use as any other Whisper model via HF transformers, or use a faster decoder like [faster-whisper](https://github.com/guillaumekln/faster-whisper).
|
59 |
+
|
60 |
+
|
61 |
+
#### Limitations and bias
|
62 |
+
|
63 |
+
Since this model was trained on mostly broadcast speech and texts from the web, it might have problems correctly decoding the following:
|
64 |
+
* Speech containing technical and other domain-specific terms
|
65 |
+
* Children's speech
|
66 |
+
* Non-native speech
|
67 |
+
* Speech recorded under very noisy conditions or with a microphone far from the speaker
|
68 |
+
* Very spontaneous and overlapping speech
|
69 |
+
|

+

## Training procedure
|
85 |
+
|
86 |
+
Finetuned using Espnet, and then comverted to transformers format using [this](https://gist.github.com/alumae/2dcf473b667cec9d513b80ea24e94672) script.
|
87 |
+
Finetuning procedure is similar to [this](https://huggingface.co/espnet/shihlun_asr_whisper_medium_finetuned_librispeech100) model.
