+Whisper is a pre-trained model for automatic speech recognition (ASR) and speech translation. Fine-tuned on 75000 wavs 
+of labelled synthetic IPA data (generated using the goruut 0.7.0 phonemizer), Whisper models demonstrate a strong ability
 to generalise to many languages, datasets and domains **without** the need for fine-tuning.
 
 Whisper was proposed in the paper [Robust Speech Recognition via Large-Scale Weak Supervision](https://arxiv.org/abs/2212.04356)
