Open the original- What it measures
- A substitution error is a word the recognizer replaces with a different word. Phonetic here means the replacement sounds like the spoken word.
- What it does not show
- The finding is from Vietnamese, a tonal language with many sound-alike syllables. It has not been measured for every language pair.
