Our own models where general ones struggle
General speech models are weaker in smaller languages. For Slovak we trained our own model, gaston-sk-v2, on about 2,600 hours of Slovak speech, and we train models for Amharic and Irish too.
- about half the word errors of OpenAI Whisper large-v3 on Slovak
- keeps the names and surnames other models drop
- standard written Slovak with proper diacritics

How accurate is the transcription?
On clean speech the model behind Gaston gets 94 to 97 of every 100 words right in the major European languages. For Slovak we use our own model with an average of 93.35% words right on 8 test sets. Background noise and people talking over each other lower the accuracy.
