WAcc (Word Accuracy) measures how accurately speech recognition systems transcribe spoken words compared to a reference transcript.
What is an example of WAcc?
If 95 out of 100 words in an audio clip are transcribed correctly, the WAcc is 95%.
How does WAcc work?
It calculates the ratio of correctly recognized words to the total number of words, factoring in substitutions, deletions, and insertions.
How does ai-coustics use WAcc?
Our technology can help improve WAcc for voice agents and other voice AI products, because audio enhancement impacts downstream ASR performance. Cleaner speech typically yields higher accuracy.
