This paper deals with the influence of ambient speech on individual speech productions. A methodological framework is defined to gather the experimental data necessary to feed computer models simulating self-organisation in phonological systems. Two experiments were carried out. Experiment 1 was run on French native speakers from two regiolects of Belgium: two from Liège and two from Brussels. When exposed to the way of speaking of the other regiolect via loudspeakers, the speakers of one regiolect produced vowels that were significantly different from their typical realisations, and significantly closer to the way of speaking specific of the other regiolect. Experiment 2 achieved a replication of the results for 8 Mons speakers hearing a Liège speaker. A significant part of the imitative effect remained up to 10 min after the end of the exposure to the other regiolect productions. As a whole, the results suggest that: (i) imitation occurs automatically and unintentionally, (ii) the modified realisations leave a memory trace, in which case the mechanism may be better defined as 'mimesis' than as 'imitation'. The potential effects of multiple imitative speech interactions on sound change are discussed in this paper, as well as the implications for a general theory of phonetic implementation and phonetic representation.

    • "This distinction matters, because there are many instances in which hearing other-produced speech influences perception and production. Properties of the speech sounds in the environment can be assimilated into a speaker's output (Delvaux & Soquet, 2007; Pickering & Garrod, 2004), and speech that a person is trying to ignore can be confused with attended speech, particularly if the utterances are semantically related (Brungart, 2001; Gray & Wedderburn, 1960). Thus, had participants heard any voice (not necessarily their own), they might have made the same misattributions. "

    • "Most recent studies on phonetic convergence and imitation use rather controlled and limited speech material, often without real conversational interaction , or focus on only specific target words or phrases in conversations [6] [3] [9] [1] [8] [16] [4] [18] [17]. Few recent studies use larger-scale fully annotated corpora such as the quasi-spontaneous Columbia Games Corpus [11]. "

    ABSTRACT: This paper describes current and future contents of the (GErman COnversations) conversations database and promotes investigating the role of attention in phonetics research. GECO is freely available for non-commercial use. It consists of conversations of high-audio quality between female subjects , together with results of personality tests of each participant, and participants' ratings of each other and of the conversation. To our knowledge it is currently the largest German database of this type. This corpus will be doubled in size by adding more dialogs in the next two years, and these new speech data will be complemented by results of several attention tests. Some of these tests will follow established test paradigms, but we also suggest a new, less artificial paradigm for testing attention. We describe the existing GECO corpus as well as the future additions including the proposed test in this paper.

    • "In addition to Babel's work on New Zealand English, Delvaux and Soquet (2007) have found cross-dialect accommodation in regional varieties of Belgian French, while Phillips and Clopper (2012) found no acoustic evidence of accommodation (though weak perceptual evidence). Kim et al. (2011), comparing accommodation between D(ialect)1-D1 speakers, D1-D2 speakers, and L(anguage)1-L2 speakers find convergence in the first, but not the two latter pairings, summarizing that their results " generally support the hypothesis that closer interlocutor language distance facilitates phonetic convergence between talkers in conversations " (p.

    ABSTRACT: Twenty women from Christchurch, New Zealand and sixteen from Columbus Ohio (dialect region U.S. Midland) participated in a bimodal lexical naming task where they repeated monosyllabic words after four speakers from four regional dialects: New Zealand, Australia, U.S. Inland North and U.S. Midland. The resulting utterances were acoustically analyzed, and presented to listeners on Amazon Mechanical Turk in an AXB task. Convergence is observed, but differs depending on the dialect of the speaker, the dialect of the model, the particular word class being shadowed, and the order in which dialects are presented to participants. We argue that these patterns are generally consistent with findings that convergence is promoted by a large phonetic distance between shadower and model (Babel, 2010, contra Kim, Horton & Bradlow, 2011), and greater existing variability in a vowel class (Babel, 2012). The results also suggest that more comparisons of accommodation towards different dialects are warranted, and that the investigation of the socio-indexical meaning of specific linguistic forms in context is a promising avenue for understanding variable selectivity in convergence.
