background and aim: quick speech in noise (q-sin) test has popularity for evaluating speech recognition in noise. the present study has been paid to build five new persian lists with respect to all possible factors affecting the test, to determine validity of the test and to run five lists for normal hearing subjects and assessment of reliability. methods: to build lists, frequent, familiar and...

The speech reception threshold (SRT) is the noise level at which the speech recognition rate of a test person is 50%. SRT measurement is relevant for patient screening, psychoacoustic research and algorithm development in hearing aids and cochlear implants. In this paper, we report on our efforts to automate SRT measurement using an automatic speech recognizer. During a test, sentences are pres...

A conventional measure to determine the ability to understand speech in noisy backgrounds is the so-called speech reception threshold (SRT) for sentences. It yields the signal-to-noise ratio (in dB) for which half of the sentences are correctly perceived. The SRT defines to what degree speech must be audible to a listener in order to become just intelligible. There are indications that elderly ...

Several binaural audio signal enhancement algorithms were evaluated with respect to their potential to improve speech intelligibility in noise for users of bilateral cochlear implants (CIs). 50% speech reception thresholds (SRT50) were assessed using an adaptive procedure in three distinct, realistic noise scenarios. All scenarios were highly nonstationary, complex, and included a significant a...

Binaural hearing offers several advantages over monaural hearing including improved speech understanding in the presence of background noise and the ability to localize the source of sounds. Patients who have undergone unilateral cochlear implantation perform poorly at these binaural tasks despite their improved hearing capabilities. Bilateral cochlear implants have restored these abilities in ...

A “microscopic” model of phoneme recognition, which includes an auditory model and a simple speech recognizer, is adapted to model the recognition of single words within whole German sentences. “Microscopic” in terms of this model is defined twofold, first, as analyzing the particular spectrotemporal structure of the speech waveforms, and second, as basing the recognition of whole sentences on ...

Understanding speech in noisy environments is often taken for granted; however, this task is particularly challenging for people with cochlear hearing loss, even with hearing aids or cochlear implants. A significant limitation to improving auditory prostheses is our lack of understanding of the neural basis for robust speech perception in noise. Perceptual studies suggest the slowly varying com...
