For the speech enhancement task, our experiments show that HDNN significantly outperforms DNN in terms of perceptual evaluation of speech quality (PESQ), which is an objective measure highly correlated to subjective testing of listening quality.
Should the teaching and testing of listening, for example, incorporate non-native English accents into instructional or assessment materials?
Participants of this study frequently complained of a lack of the infrastructure necessary to implement oral tests, especially tests of listening comprehension.
DIALANG, a project which was explicitly developed using the CEFR as the basis (Alderson 2005), provides online diagnostic tests of listening, reading, writing, structures, and vocabulary in 14 languages at six CEFR levels.
For the language requirement to be waived, a student must pass a placement test for admission into an advanced-level course or, for languages not regularly offered at Yale, an equivalent test of speaking, listening, reading, and writing skills administered through the Center for Language Study.
The reliability alpha for this test of L2 listening proficiency was.85.85
As a result, this new test has brought unintended, but predictable, negative effects on teaching, in the sense that frequent practice of listening test items and drilling on grammar and translation were the main instructional practices with respect to listening in English classes.
The lasso, elastic-net and stepwise algorithms are tested for listening tests of consumer product for which 91 metrics are used as potential predictors.
The main advantage of this system is that it works automatically without human interaction which is a great problem in collective realization of listening tests (more people together for keeping the same test conditions), and the obtained results can numerically be matched as the objective comparison criterion.
After Cash's death, Rubin was searching for a challenge with an even higher degree of difficulty, a greater test for his powers of listening.
