Bi-directional Lattice Recurrent Neural Networks for Confidence Estimation
This project helps speech recognition engineers improve the accuracy of confidence scores from automatic speech recognition (ASR) systems. It takes speech 'lattices' or 'confusion networks' from your ASR output and provides more reliable confidence predictions, not just for the most likely word sequence but for all alternative word hypotheses. This is ideal for ASR system developers, researchers, or anyone building applications that rely on highly accurate confidence estimation for spoken language.
No commits in the last 6 months.
Use this if you need to significantly improve the confidence scores generated by your automatic speech recognition (ASR) system, especially when working with alternative word hypotheses beyond just the single-best prediction.
Not ideal if you are looking for an off-the-shelf, end-to-end ASR system or a solution that doesn't require pre-processed speech 'lattices' or 'confusion networks' as input.
