# Whisper Tiny Galician
|
| 32 |
|
| 33 |
+
## Model summary
|
| 34 |
+
|
| 35 |
+
**Whisper Tiny Galician** is an automatic speech recognition (ASR) model for **Galician (gl)** speech. It is fine-tuned from [openai/whisper-tiny] on the **Galician portion of Mozilla Common Voice 13.0**, achieving a **Word Error Rate (WER) of 26.13%** on the Common Voice evaluation split.
|
| 36 |
+
|
| 37 |
+
This model provides lightweight transcription capabilities for Galician speech, suitable for low-resource applications or devices with limited computational capacity.

## Model description
|
| 42 |
|
| 43 |
+
* **Architecture:** Transformer-based encoder–decoder (Whisper)
|
| 44 |
+
* **Base model:** openai/whisper-tiny
|
| 45 |
+
* **Language:** Galician (gl)
|
| 46 |
+
* **Task:** Automatic Speech Recognition (ASR)
|
| 47 |
+
* **Output:** Text transcription in Galician
|
| 48 |
+
* **Decoding:** Autoregressive sequence-to-sequence decoding
|
| 49 |
+
|
| 50 |
+
This tiny model leverages Whisper’s multilingual pretraining and is fine-tuned on Galician speech data to provide basic transcription functionality for a low-resource language, ideal for experimentation and lightweight applications.

## Intended use
|
| 55 |
+
|
| 56 |
+
### Primary use cases
|
| 57 |
+
|
| 58 |
+
* Lightweight transcription of Galician audio recordings
|
| 59 |
+
* Low-resource or offline ASR pipelines
|
| 60 |
+
* Educational and research purposes
|
| 61 |
+
|
| 62 |
+
### Intended users
|
| 63 |
+
|
| 64 |
+
* Researchers working on Galician or low-resource ASR
|
| 65 |
+
* Developers building Galician speech applications
|
| 66 |
+
* Academic or institutional users
|
| 67 |
|
| 68 |
+
### Out-of-scope use
|
| 69 |
|
| 70 |
+
* High-accuracy transcription requirements
|
| 71 |
+
* Real-time or low-latency ASR without optimization
|
| 72 |
+
* Speech translation tasks
|
| 73 |
+
|
| 74 |

|
| 75 |
+
|
| 76 |
+
## Limitations and known issues
|
| 77 |
+
|
| 78 |
+
* Performance may degrade on:
|
| 79 |
+
* Noisy or low-quality recordings
|
| 80 |
+
* Conversational or spontaneous speech
|
| 81 |
+
* Accents underrepresented in Common Voice
|
| 82 |
+
* Transcription errors are expected due to the small model size
|
| 83 |
+
* Dataset biases from Common Voice may be reflected in outputs
|
| 84 |
+
|
| 85 |
+
Users are encouraged to evaluate the model on their own data before deployment.
