TL;DR: Consideration of average discrepancies between mean perception and mean production data suggested that interpretation of trends in production data may be assisted by taking a measure of the point of overlap between voiced and voiceless productions, rather than the simple average of their means.
Abstract: 34 children (average age 3; 3) furnished perception and production data on five initial voiced-voiceless stop cognates. In addition to the usual systematic effects of place of articulation, significan

TL;DR: Age effects for stop consonant voicing and delta were not statistically significant, but correlations between delta and stop voicing were less often significant and sometimes reversed in the children, providing some evidence of immature aerodynamic control.
Abstract: Previous authors have established that stop consonant voicing is more limited in young children than adults, and have ascribed this to immature vocal-tract pressure management Physical development relevant to speech aerodynamics continues into adolescence, suggesting that consonant voicing development may also persist into the school-age years This study explored the relationship between stop consonant voicing and intraoral pressure contours in women, 5year olds, and 10year olds Productions of intervocalic /p b/ were recorded from eight speakers at each age Measures were made of stop consonant voicing and δ, a measure designed to characterize the time course of intraoral pressure increase in stops, following Muller and Brown [Speech and Language: Advances in Basic Research and Practice, edited by N Lass (Academic, Madison, 1980), Vol 4, pp 318–389] Age effects for stop consonant voicing and δ were not statistically significant, but correlations between δ and stop voicing were less often significan

TL;DR: Results provide evidence that DY children performances can be accounted for by laborious phonological syllable-based procedures and also degraded phonological representations.
Abstract: This study investigated the status of phonological representations in French dyslexic children (DY) compared with reading level- (RL) and chronological age-matched (CA) controls. We focused on the syllable's role and on the impact of French linguistic features. In Experiment 1, we assessed oral discrimination abilities of pairs of syllables that varied as a function of voicing, mode or place of articulation, or syllable structure. Results suggest that DY children underperform controls with a 'speed-accuracy' deficit. However, DY children exhibit some similar processing than those highlighted in controls. As in CA and RL controls, DY children have difficulties in processing two sounds that only differ in voicing, and preferentially process obstruent rather than fricative sounds, and more efficiently process CV than CCV syllables. In Experiment 2, we used a modified version of the Cole, Magnan, and Grainger's (Applied Psycholinguistics 20:507-532, 1999) paradigm. Results show that DY children underperform CA controls but outperform RL controls. However, as in CA and RL controls, data reveal that DY children are able to use phonological procedures influenced by initial syllable frequency. Thus, DY children process syllabically high-frequency syllables but phonemically process low-frequency syllables. They also exhibit lexical and syllable frequency effects. Consequently, results provide evidence that DY children performances can be accounted for by laborious phonological syllable-based procedures and also degraded phonological representations.

TL;DR: This paper addresses three issues raised by observations of the role of systematically-varying fine phonetic detail in speech: the representation of linguistic knowledge so that it simultaneously accommodates detail and abstraction; the nature of phonetic categories; and the type of processes that must underlie speech perception.
Abstract: This paper addresses three issues raised by observations of the role of systematically-varying fine phonetic detail in speech: the representation of linguistic knowledge so that it simultaneously accommodates detail and abstraction; the nature of phonetic categories; and the type of processes that must underlie speech perception. Evidence is adduced from the anatomy and physiology of the brain to support arguments for a polysystemic view of speech perception. 1. The particular 1.1 History and definition of the term "fine phonetic detail" (FPD): When John Local talked in the 1980s about fine phonetic detail, he was describing phonetic phenomena such as resonances associated with liquid consonants in English that were systematically distributed but not systematically treated in conventional phonetic description. They tended to be hard to notice too. Since then, the term FPD has come to be applied to anything that is not considered a major, usually local, perceptual cue for phonemic contrasts in the citation forms of lexical items. In this broader usage, some FPD is indeed 'fine', and subtle, but other types are perfectly audible; they have just not been factored into the prevailing view that perceptual processing of phonetic information is largely aimed at identifying strings of features or phonemes that allow words to be distinguished. FPD cuts across traditional subdisciplines of enquiry. It does not just distinguish words, but also the wider phonological and grammatical structure of the message. For example, grammatical function words have a narrower range of sound patterns than content words, and undergo different connected speech processes; and each type of function word (e.g. auxiliary verbs, articles) has its own distinct system of contrasts (e.g. Ogden 1999; Local 2003). FPD also reflects function and structure of the smaller units that comprise words, and of larger groupings, influencing everything necessary for successful communication: phonological, morphological, grammatical, pragmatic, interactional (see Phonetica Volume 61, especially papers by Local, Ogden, and Plug). FPD indicating a single linguistic distinction can involve many acoustic properties distributed over long stretches of speech (Hawkins and Smith 2001; Local 2003) e.g. traces of English /r/ can occur several syllables before the main /r/ segment and influence perception (Hawkins and Slater 1994; West 1999a, b; Heid and Hawkins 2000; Coleman 2003). Even well-researched distinctions like coda voicing involve multiple distinctions, some of which are less local than was until recently assumed (Hawkins and Nguyen 2004). Thus, much FPD—the sort discarded by traditional abstractionist phonological and perceptual models as uninteresting or due to random effects—in fact systematically reflects many different aspects of meaning that are crucial to the maintenance of normal conversation: lexical, grammatical, and interactional differences. As Nguyen notes "The goal of current research on FPD is to show that FPD is important in speech (processing), and, therefore, that a change of theoretical perspective is called for." (in press :8). If such a changed perspective proves valuable, the term fine phonetic detail can largely be replaced by "phonetic information".

TL;DR: This work augments the Mel cepstral feature representation with voicing features from an independent front end and computed the normalized autocorrelation peak and a newly proposed entropy of the high-order cepstrum to integrate the voicing features into SRI's DECIPHER system.
Abstract: We augment the Mel cepstral (MFCC) feature representation with voicing features from an independent front end. The voicing feature front end parameters are optimized for recognition accuracy. The voicing features computed are the normalized autocorrelation peak and a newly proposed entropy of the high-order cepstrum. We explored several alternatives to integrate the voicing features into SRI's DECIPHER system. Promising early results were obtained in a simple system concatenating the voicing features with MFCC features and optimizing the voicing feature window duration. Best results overall came from a more complex system combining a multiframe voicing feature window with the MFCC plus third differential features using linear discriminant analysis and optimizing the number of voicing feature frames. The best integration approach from the single-pass system experiments was implemented in a multi-pass system for large vocabulary testing on the Switchboard database. An average WER reduction of 2% relative was obtained on the NIST Hub-5 dev2001 and eval2002 databases.
