Whisper Small ta - Lingalingeswaran

This model is a fine-tuned version of openai/whisper-small on the Common Voice 11.0 dataset. It achieves the following results on the evaluation set:

Loss: 0.2150
Wer: 43.3196

Model description

This Whisper model has been fine-tuned specifically for the Tamil language using the Common Voice 11.0 dataset. It is designed to handle tasks such as speech-to-text transcription and language identification, making it suitable for applications where Tamil is a primary language of interest. The fine-tuning process focused on enhancing performance for Tamil, aiming to reduce the error rate in transcriptions and improve general accuracy.

Intended uses & limitations

Intended Uses: Speech-to-text transcription in Tamil

Limitations: May not perform as well on languages or dialects that are not well-represented in the Common Voice dataset. Higher Word Error Rate (WER) in noisy environments or with speakers who have heavy accents not covered in the training data. The model is optimized for Tamil; performance in other languages may be suboptimal.

Training and evaluation data

The training data for this model consists of voice recordings in Tamil from the Mozilla-foundation/Common Voice 11.0 dataset. The dataset is a crowd-sourced collection of transcribed speech, ensuring diversity in terms of speaker accents, age groups, and speech styles.
