sauti-whisper-small-swh

This model is a fine-tuned version of openai/whisper-small on the WAXAL (WaxalNLP) dataset (config: swa_tts).

It achieves the following results on the evaluation set:

Loss: 1.3956
WER: 56.1205

Model description

openai/whisper-small fine-tuned for Swahili ASR as part of the Sauti project at MsingiAI.

Intended uses & limitations

Intended use: Automatic speech recognition for Swahili.

Limitations:

The training data comes from a dataset originally curated for TTS; performance may not generalize well to noisy, conversational, or code-switched audio.
Whisper models have a maximum decoder target length (448 tokens). Long transcripts were truncated during preprocessing.
