### Training Data
The model was fine-tuned on the `Lagyamfi/akan_audio_processed` dataset from Hugging Face. This dataset contains Akan audio clips and corresponding transcriptions, including various augmented versions such as pitch-shifted and noise-added variants.
### Training Procedure
#### Preprocessing
- The audio was resampled to 16kHz.
- Text was tokenized into the appropriate input format for Whisper.
#### Training Hyperparameters
- **Training regime:** Mixed-precision (fp16) training
- **Batch size:** 4
- **Learning rate:** 1e-4
- **Gradient accumulation steps:** 2
#### Speeds, Sizes, Times
- **Total training time:** Approximately 30 minutes
- **Model checkpoint size:** Approximately 1.8GB
## Evaluation
### Testing Data, Factors & Metrics
#### Testing Data
The test data is sourced from the `Lagyamfi/akan_audio_processed` dataset on Hugging Face, which includes a separate test split specifically for evaluating the model’s performance.
#### Factors
Performance was evaluated across variations within the Akan language as represented in the dataset, including factors like audio clarity, accent, and background noise.
#### Metrics
The model’s performance is evaluated using the Word Error Rate (WER) metric, which measures the rate of errors in transcriptions by comparing the predicted transcription to the ground truth.
### Results
- **Word Error Rate (WER):** 0.3772
This WER indicates that approximately 37.72% of words in the transcriptions contain errors relative to the ground truth on the test dataset.

# Model Card for Akan Whisper Model

|
23 |
## Model Details
|
24 |
|
25 |
### Model Description
|
26 |
|
27 |
+
This model is a fine-tuned version of OpenAI's Whisper model, designed for Automatic Speech Recognition (ASR) on the Akan language, a low-resource language spoken in Ghana. The model was trained on a dataset containing Akan audio clips and corresponding transcriptions, enabling it to transcribe spoken Akan into text.

+
- **Shared by:** Mark Atta Mensah
|
31 |
+
- **Model type:** Automatic Speech Recognition (ASR)
|
32 |
+
- **Language(s) (NLP):** Akan (Twi)
|
33 |
+
- **Finetuned from model:** openai/whisper-small
|
|
|
|
|
34 |
|
35 |
## Uses
|
36 |
|
|
|
|
|
37 |
### Direct Use
|
38 |
|
39 |
+
This model can be directly used for transcribing Akan speech into text. It is suitable for applications like voice assistants, transcription services, and other language-based solutions that require Akan language support.
|
|
|
|
|
|
|
|
|
40 |
|
41 |
+
### Downstream Use
|
42 |
|
43 |
+
This model can be fine-tuned further or incorporated into larger applications that require multi-language ASR capabilities or specific domain adaptation for Akan.
|
44 |
|
45 |
### Out-of-Scope Use
|
46 |
|
47 |
+
The model is not suitable for languages other than Akan (Twi) and may not perform well on other low-resource languages without additional fine-tuning.
|
|
|
|
|
48 |
|
49 |
## Bias, Risks, and Limitations
|
50 |
|
51 |
+
As with any ASR model, this model may have biases based on the dataset it was trained on. Potential biases in the training data could lead to underperformance on accents, dialects, or language variations not well represented in the data.
|
|
|
|
|
52 |
|
53 |
### Recommendations
|
54 |
|
55 |
+
Users should be aware of these limitations and assess the model’s performance on specific applications before deployment.
