How does recognition score works?

[luiso1979]

Hello,

I’m not an expert in Speech Recognition. Could someone please explain to me how the recognition score works. What is the correspondence between the score and the reliability of the recognition? Which is the minimum score that I should consider to ignore the hypothesis?

Thanks in advance

Luis

Hi Luis,

It’s very much relative to that particular speaker and session and the size of the language model. It can’t be reliably used to create arbitrary cutoffs in my experience except perhaps with extremely low values (like -500000 or lower). I wish it were more useful for the task of evaluating accuracy but I haven’t encountered a case yet where it was possible to rely on the score so I’ve reversed my old advice that it could be used in this way.
