Ombi WER (Word Error Rate)?
Tasso d'errore di parola (WER) è la misura standard per misurare l'accuratezza del riconoscimento vocale. Calcola il percento di parole in una trascrizione che differiscono dalla riferimento. Un WER di 5% significa che circa 5 su ogni 100 parole contengono un errore.
Professional human transcriptionists typically achieve a WER of 4-5%. The best AI models now match or approach human-level accuracy on clean audio.
