Trying a understand a patent on confidence score

[dovark]

I'm reading this patent https://www.google.com/patents/EP1679694B1. I hoped to read a way to get ASR confidence score, but all I got from the patent is that the ASR module (102) somehow produces the confidence scores based on number of hypothesized words. Does anyone find anything more than this in the patent?

Any other patents you'd like to recommend reading on ASR confidence score? (I have read a bunch of papers, and was hoping that I will find something different in patents)

Thanks.

Patents are not a good place for finding a truth just because they often disclose a random ideas, not something useful.

Confidence estimation is a solved problem and the optimal algorithm to implement a good estimation is known. It's done with a framework of statistical hypothesis testing. Confidence estimation is well described in a papers like:
