multilingual-whisper-v3-turbo

This model is a fine-tuned version of openai/whisper-large-v3-turbo on the dsfsi-anv dataset. It achieves the following results on the evaluation set:

• Loss: 0.2427
• Wer: 0.1501
• Cer: 0.0510

Model description

This model is a fine-tuned version of the Whisper Large V3 Turbo model, optimized for multilingual Automatic Speech Recognition (ASR). It has been trained on the ANV (Swivuriso) dataset to improve performance on specific target languages and domains represented in that corpus.

Whisper is a Transformer-based encoder-decoder model, also referred to as a sequence-to-sequence model. It was trained on weak supervision using large-scale noisy data, and this fine-tuning step adapts it specifically for the languages and accents found in the dsfsi-anv dataset.

Intended uses & limitations

Intended Uses

• Automatic Speech Recognition (ASR): The model is primarily intended to transcribe audio in the languages present in the training data.
• Research: Suitable for researchers studying low-resource language adaptation and fine-tuning efficiency.

Limitations

• Hallucinations: Like the base Whisper model, this model may generate repetitive text or hallucinations, particularly in silence or with background noise.
• Domain Specificity: Performance may degrade on audio that differs significantly (in terms of accent, noise, or recording quality) from the ANV dataset.

Training and evaluation data

The model was trained on the dsfsi-anv dataset.
