An evaluation of objective quality measures for speech intelligibility prediction
نویسندگان
چکیده
In this research various objective quality measures are evaluated in order to predict the intelligibility for a wide range of non-linearly processed speech signals and speech degraded by additive noise. The obtained results are compared with the prediction results of a more advanced perceptual-based model proposed by Dau et al. and an objective intelligibility measure, namely the coherence speech intelligibility index (cSII). These tests are performed in order to gain more knowledge between the link of speech-quality and speech-intelligibility and may help us to exploit the extensive research done into the field of speech-quality for speech-intelligibility. It is shown that cSII does not necessarily show better performance compared to conventional objective (speech)-quality measures. In general, the DAU-model is the only method with reasonable results for all processing conditions.

An evaluation of objective measures for intelligibility prediction of time-frequency weighted noisy speech.
Existing objective speech-intelligibility measures are suitable for several types of degradation, however, it turns out that they are less appropriate in cases where noisy speech is processed by a time-frequency weighting. To this end, an extensive evaluation is presented of objective measure for intelligibility prediction of noisy speech processed with a technique called ideal time frequency (...

In this paper, eight state-of-the-art objective speech intelligibility prediction measures are comparatively investigated for noisy signals before and after noise-reduction processing between Mandarin and Japanese. Clean speech signals (Chinese words and Japanese words) were first corrupted by three types of noise at two signal-to-noise ratios and then processed by normal-hearing listeners for ...

Unwanted noises have a negative influence over communication because it disturbs the conversation and make the communication impossible. Speech enhancement algorithms are used for improving the quality and intelligibility or to reduce listener fatigues. Assessment of speech quality can be done by using either subjective listening test or objective quality measure. Evaluation of several objectiv...

In this paper, we evaluate the performance of several state-of-the-art objective measures in terms of predicting speech intelligibility in Mandarin of the processed noisy signals by speech enhancement algorithms. The speech signals were first corrupted by three types of noises at two signal-to-noise ratios, followed by four classes of speech enhancement algorithms. The objective intelligibility...
متن کاملSpeech intelligibility after repair of cleft lip and palate
Background: Intelligibility refers to understandability of speech; and lack of it can negatively affect children’s overall communication effectiveness. Children with repaired cleft lip and/or cleft palate (CL/P) may experience poor speech intelligibility. This study aimed at evaluating speech intelligibility in children with repaired CL/P who had not been referred to sp...
