whisper-large-v3-turbo-FLEURS-GL

This model is a fine-tuned version of openai/whisper-large-v3-turbo trained on juanjucm/FLEURS-SpeechT-GL-EN for Galician Text to Speech task. It takes galician speech audios as input and generates the correspondant transcription.

This Automatic Speech Recognition model, was developed to be the first stage of a Speech Translation cascade system for transcribing and translating Galician audios into English texts. After this first STT step, this Galician-to-English MT model can be applied over the generated Galician transcriptions to get English text translations.

The motivation behind this work is to increase the visibility of the Galician language, making it more accessible for non-Galician speakers to understand and engage with Galician audio content.

This model was developed during a 3-week Speech Translation workshop organised by Yasmin Moslem.
