## Bias, Risks, and Limitations
|
35 |
-
|
36 |
-
Language detection capability of this model has been degraded during training - it is intended for mostly-hebrew audio transcription.
|
37 |
-
Language token should be explicitly set to Hebrew.
|
38 |
-
|
39 |
-
Additionally, the tanslation task was not trained and also degraded. This model would not be able to translate in any reasonable capacity.
|
40 |
-
|
41 |
-
## How to Get Started with the Model
|
42 |
-
|
43 |
-
Please follow the original [model card](https://huggingface.co/openai/whisper-large-v3#usage) for usage details - replacing with this model name.
|
44 |
-
You can also fine other weight formats ad quantizations on the [ivrit ai](https://huggingface.co/ivrit-ai) HF page.
|
45 |
-
|
46 |
-
We created some simple example scripts using this model and weights for other inference runtimes.
|
47 |
-
Find those in the ["examples"](https://github.com/ivrit-ai/asr-training/tree/master/examples) folder within the training GitHub repo.

## Training Details
|
50 |
-
|
51 |
-
### Training Data
|
52 |
-
|
53 |
-
This model was trained on the following datasets:
|
54 |
-
|
55 |
-
- [ivrit-ai/crowd-transcribe-v5](https://huggingface.co/datasets/ivrit-ai/crowd-transcribe-v5) - Publicly accessible audio sources have been crowd-transcribed segment-by-segment - ~300h
|
56 |
-
- [ivrit-ai/crowd-recital-whisper-training](https://huggingface.co/datasets/ivrit-ai/crowd-recital-whisper-training) - Crowd-sourced recording of Wikipedia article snippets. ~50h
|
57 |
-
- [ivrit-ai/knesset-plenums-whisper-training](https://huggingface.co/datasets/ivrit-ai/knesset-plenums-whisper-training) - A subset of a Knesset (Israeli house of representatives) plenum protocols. ~4700h
|
58 |
-
|
59 |
-
### Training Procedure
|
60 |
-
|
61 |
-
This model was trained in two main phases:
|
62 |
-
- Knesset based pre-training - over all ~4700h of data - 3 epochs, ~54h run
|
63 |
-
- Mixed post-training over all crowd-transcribe-v5 (300h), crowd-recital-whisper-training (50h) and highest-quality filtered knessets data (150h) - 1 epoch
|
64 |
-
- Interleaving of datasets with sampling probs: (0.9, 0.025, 0.075) respectively
|
65 |
-
- Note that crowd-transcribe-v5 has about 5x shorter samples on average thus the over-sampling.
|
66 |
-
|
67 |
-
This model is a weighted-average of the 3 lowest eval loss checkpoints from the same training run.
|
68 |
-
Training code can be found on the ivrit-ai Github [here](https://github.com/ivrit-ai/asr-training)
|
69 |
-
|
70 |
-
#### Preprocessing
|
71 |
-
|
72 |
-
The "Crowd Recital" and "Knesset" datasets contain timestamps and previous text following the Whisper expected inputs.
|
73 |
-
Timestamps were used from 40% of samples from those datasets, and 50% of the previous text was used.
|
74 |
-
|
75 |
-
The "Crowd Transcribe" datasets has no timestamps or previous text and this preprocessing only included melspec feature extraction and text encoding.
|
76 |
-
|
77 |
-
Preprocessing code can be found within the training code [repository](https://github.com/ivrit-ai/asr-training).
|
78 |
-
|
79 |
-
Datasets were interleaved with 0.15:0.8:0.05 ratio (knesset:crowd-transcribe:crowd-recital).
|
80 |
-
|
81 |
-
#### Training Hyperparameters
|
82 |
-
|
83 |
-
- **Training regime:** bf16 mixed precision with sdpa
|
84 |
-
- **Learning Rate:** 1e-5, Linear decay, 800 steps warmup for 3 epochs
|
85 |
-
- **Batch Size:** 32
|
86 |
-
|
87 |
-
#### Training Hardware / Duration
|
88 |
-
|
89 |
-
- **GPU Type:** 8 x Nvidia A40 machine
|
90 |
-
- **Duration:** ~60 run across both phases
|
91 |
-
|
92 |
-
