Prosodic detail in Neapolitan Italian

Recent findings on phonetic detail have been taken as supporting exemplar-based approaches to prosody. Through four experiments on both production and perception of both melodic and temporal detail in Neapolitan Italian, we show that prosodic detail is not incompatible with abstractionist approaches either. Specifically, we suggest that the exploration of prosodic detail leads to a refined understanding of the relationships between the richly specified and continuous varying phonetic information on one side, and coarse phonologically structured contrasts on the other, thus offering insights on how pragmatic information is conveyed by prosody

Effects of Prosodic and Lexical Constraints on Parsing in Young Children (and Adults)

Prior studies of ambiguity resolution in young children have found that children rely heavily on lexical information but persistently fail to use referential constraints in online parsing [Trueswell, J.C., Sekerina, I., Hill, N.M., & Logrip, M.L. (1999). The kindergarten-path effect: Studying on-line sentence processing in young children. Cognition, 73, 89134; Snedeker, J. & Trueswell, J. (2004). The developing constraints on parsing decisions: The role of lexical-biases and referential scenes in child and adult sentence processing. Cognitive Psychology, 49(3), 238-299]. This pattern is consistent with either a modular parsing system driven by stored lexical information or an interactive system which has yet to acquire low-validity referential constraints. In two experiments we explored whether children could use a third constraint-prosody-to resolve globally ambiguous prepositional-phrase attachments ("You can feel the frog with the feather"). Four to six-year-olds and adults were tested using the visual world paradigm. In both groups the fixation patterns were influenced by lexical cues by around 200 ms after the onset of the critical PP-object noun ("feather"). In adults the prosody manipulation had an effect in this early time window. In children the effect of prosody was delayed by approximately 500 ms. The effects of lexical and prosodic cues were roughly additive: prosody influenced the interpretation of utterances with strong lexical cues and lexical information had an effect on utterances with strong prosodic cues. We conclude that young children, like adults, can rapidly use both of these information sources to resolve structural ambiguities.Psycholog

The listening talker: A review of human and algorithmic context-induced modifications of speech

International audienceSpeech output technology is finding widespread application, including in scenarios where intelligibility might be compromised - at least for some listeners - by adverse conditions. Unlike most current algorithms, talkers continually adapt their speech patterns as a response to the immediate context of spoken communication, where the type of interlocutor and the environment are the dominant situational factors influencing speech production. Observations of talker behaviour can motivate the design of more robust speech output algorithms. Starting with a listener-oriented categorisation of possible goals for speech modification, this review article summarises the extensive set of behavioural findings related to human speech modification, identifies which factors appear to be beneficial, and goes on to examine previous computational attempts to improve intelligibility in noise. The review concludes by tabulating 46 speech modifications, many of which have yet to be perceptually or algorithmically evaluated. Consequently, the review provides a roadmap for future work in improving the robustness of speech output
