WER (Kelime Hata Oranı) nedir?

Sözcük Hata Oranları (WER) konuşma tanıma doğruluğunu ölçmek için standart bir ölçüdür. Bir metin metninde referanstan farklı olan kelimelerin yüzdesini hesaplar. %5'lik bir WER her 100 kelimeden yaklaşık 5'inin hata içerdiği anlamına gelir. Daha düşük daha iyidir.

Profesyonel insan transkripsiyonistleri genellikle %4-5'lik bir WER elde ederler.En iyi yapay zeka modelleri artık temiz ses üzerinde insan seviyesinde doğruluğa uyum sağlar veya yaklaşır.
