Query: Acoustics-guided evaluation (AGE): a new measure for estimating
  performance of speech enhancement algorithms for robust ASR   One challenging problem of robust automatic speech recognition (ASR) is how
to measure the goodness of a speech enhancement algorithm (SEA) without
calculating the word error rate (WER) due to the high costs of manual
transcriptions, language modeling and decoding process. Traditional measures
like PESQ and STOI for evaluating the speech quality and intelligibility were
verified to have relatively low correlations with WER. In this study, a novel
acoustics-guided evaluation (AGE) measure is proposed for estimating
performance of SEAs for robust ASR. AGE consists of three consecutive steps,
namely the low-level representations via the feature extraction, high-level
representations via the nonlinear mapping with the acoustic model (AM), and the
final AGE calculation between the representations of clean speech and degraded
speech. Specifically, state posterior probabilities from neural network based
AM are adopted for the high-level representations and the cross-entropy
criterion is used to calculate AGE. Experiments demonstrate AGE could yield
consistently highest correlations with WER and give the most accurate
estimation of ASR performance compared with PESQ, STOI, and acoustic confidence
measure using Entropy. Potentially, AGE could be adopted to guide the parameter
optimization of deep learning based SEAs to further improve the recognition
performance.
