“…The current study did not find a significant effect of increasing F0 on intelligibility, which echoes studies such as Bond and Moore (1994) and Hazan and Markham (2004), who reported that the intelligibility of speech in noise did not correlate with F0 mean. Barker and Cooke (2007) found that speech intelligibility was correlated with fundamental frequency (F0) only for female talkers at relative low SNRs.…”

“…Cox et al, 1987;Jones et al, 2007) have demonstrated that slower speaking rates lead to increased speech intelligibility in noise, Sommers (1997) failed to find a perceptual correlate of speaking rate for young listeners with normal hearing. In addition, Bond and Moore (1994) and Hazan and Markham (2004) observed that words with longer duration led to an increased intelligibility in the presence of noise while no such effect of word duration was found in Uchanski et al (2002). These findings suggest that while it is clear that duration lengthening can increase the amount of acoustic information available, the extent to which it can improve intelligibility in the presence of noise may depend on the characteristics of the listeners and speech materials employed.…”

“…In the presence of noise, Gordon-Salant (1986) and Hazan and Simpson (1998) found that enhancement of consonant-to-vowel (C/V) amplitude ratio by 10 dB increased intelligibility by up to 10 percentage points. It has also been reported that the fine-grained acoustic-phonetic consequences of precision of articulation are able to affect speech intelligibility in noise (Bond and Moore, 1994;Hazan and Simpson, 1998). In addition, the intelligibility advantage of clear speech over normal conversational speech in the presence of noise is found to be associated with dynamic formant movement (Ferguson and Kewley-Port, 2002) and higher temporal amplitude modulation (Krause and Braida, 2004).…”

“…Vowel formant space expansion (i.e. greater discrimination between vowel categories) has also been shown to benefit speech intelligibility (Bond and Moore, 1994;Ferguson and Kewley-Port, 2002). In the presence of noise, Gordon-Salant (1986) and Hazan and Simpson (1998) found that enhancement of consonant-to-vowel (C/V) amplitude ratio by 10 dB increased intelligibility by up to 10 percentage points.…”

ACCEPTED MANUSCRIPT AbstractTalkers modify the way they speak in the presence of noise. As well as increases in voice level and fundamental frequency (F0), a flattening of spectral tilt is observed.The resulting "Lombard speech" is typically more intelligible than speech produced in quiet, even when level differences are removed. What is the cause of the enhanced intelligibility of Lombard speech? The current study explored the relative contributions to intelligibility of changes in mean F0 and spectral tilt. The roles of F0and spectral tilt were assessed by measuring the intelligibility gain of non-Lombard speech whose mean F0 and spectrum were manipulated, both independently and in concert, to simulate those of natural Lombard speech. In the presence of speechshaped noise, flattening of spectral tilt contributed greatly to the intelligibility gain of noise-induced speech over speech produced in quiet while an increase in F0 did not have a significant influence. The perceptual effects of spectrum flattening was attributed to its ability of increasing the amount of speech time-frequency plane "glimpsed" in the presence of noise. However, spectral tilt changes alone could not fully account for the intelligibility of Lombard speech. Other changes observed in Lombard speech such as durational modifications may well contribute to intelligibility.

“…Naturally produced changes in speaking rate result in a number of phonetic changes, such as vowel reduction, that occur in order to produce a word more quickly (e.g., Bond & Moore, 1994;Lieberman, 1963;Moon & Lindblom, 1994;Picheny, Durlach, & Braida, 1986;van Bergem, 1995). An example of vowel reduction and the potential decrease in intelligibility that may result from it can be seen in the words 'cat' (/kaet/) and 'cot' (/kat/).…”

Naturalistic and Experimental Analyses of Word Frequency and Neighborhood Density Effects in Slips of the Ear

A comparison of the lexical characteristics of 88 auditory misperceptions (i.e., slips of the ear) showed no difference in word-frequency, neighborhood density, and neighborhood frequency between the actual and the perceived utterances. Another comparison of slip of the ear tokens (i.e., actual and perceived utterances) and words in general (i.e., randomly selected from the lexicon) showed that slip of the ear tokens had denser neighborhoods and higher neighborhood frequency than words in general, as predicted from laboratory studies. Contrary to prediction, slip of the ear tokens were higher in frequency of occurrence than words in general. Additional laboratory-based investigations examined the possible source of the contradictory word frequency finding, highlighting the importance of using naturalistic and experimental data to develop models of spoken language processing.

Purpose The aim of the study was to develop the German Hearing in Noise Test (HINT) with female speaker by fulfilling the recommendations by International Collegium of Rehabilitative Audiology (ICRA) for using a female speaker to create new multilingual speech tests and to determine norms and to compare these norms with German male speech tests—the male speakers HINT and the Oldenburg Sentence Test (OLSA). Methods The HINT with a female speaker consists of the same speech material as the male speaking HINT. After recording the speech material, 10 normal hearing subjects were included to determine the performance–intensity function (PI function). 24 subjects were part of the measurements to determine the norms and compare them with the norms of male HINT and OLSA. Comparably, adaptive, open-set methods under headphones (HINT) and sound field (OLSA) were used. Results Acoustic phonetic analysis demonstrated significant difference in mean fundamental frequency, its range and mean speaking rate between both HINT speakers. The calculated norms by three of the tested four conditions of the HINT with a female speaker are not significantly different from the norms with a male speaker. No significant effect of the speaker’s gender of the first HINT measurement and no significant correlation between the threshold results of the HINT and the OLSA were determined. Conclusions The Norms for German HINT with a female speaker are comparable to the norms of the HINT with a male speaker. The speech intelligibility score of the HINT does not depend on the speakers’ gender despite significant difference of acoustic–phonetic parameters between the female and male HINT speaker’s voice. Instead, the speech intelligibility rating must be seen as a function of the used speech material.
