The Effect of Auditory-visu Orthographic Backgroun
نویسنده
چکیده
Visual information from the lips and face is an integral part of speech perception. In addition, orthography can play a role in disambiguating the speech signal in foreign/second language (L2) perception and production. The current study investigates the effect of auditory and visual speech information and orthographic depth, the degree to which a language is transparent (high phoneme-grapheme correspondence), or opaque (low phoneme-grapheme correspondence) on L2 acquisition. Speakers of Turkish and Australian English (transparent and opaque orthographies, respectively) were tested for their production of legal non-words in Spanish and Irish (transparent and opaque orthographies, respectively). Transparent orthographic input (Spanish) enhanced pronunciation in L2, and orthographic reproduction. Native speaker ratings of the participants’ productions also revealed that orthographic input improves accent. Overall results confirm previous findings that visual information enhances speech perception and production, and extend previous results to show the facilitative effects of orthographic input in L2 acquisition under certain conditions.

The Effect of L1 Persian on the Acquisition of English L2 Orthographic System on the Shared Grounds
This paper elaborates on Persian and English orthographic shared aspects to study the effects of L1 Persian on learning English as a foreign language. While there are some examples of letter and sound mismatches in the orthographic system of both languages, those of English are more complex than Persian. In order to see the effect of the mismatch between orthography and transcription, 40 Persia...
متن کاملOrthography influences the perception of speech in alexic patients.
Interactive models of reading propose that phonological representations directly activate and/or constrain orthographic representations through feedback. These models also predict that spoken words should activate their orthographic forms. The effect of word orthography on auditory lexical access was investigated in two patients with alexia without agraphia. Several theories of alexia suggest t...
متن کاملOrthographic Contamination of Broca’s Area
Strong evidence has accumulated over the past years suggesting that orthography plays a role in spoken language processing. It is still unclear, however, whether the influence of orthography on spoken language results from a co-activation of posterior brain areas dedicated to low-level orthographic processing or whether it results from orthographic restructuring of phonological representations ...
متن کاملOrthographic Consistency and Word-Frequency Effects in Auditory Word Recognition: New Evidence from Lexical Decision and Rime Detection
Many studies have repeatedly shown an orthographic consistency effect in the auditory lexical decision task. Words with phonological rimes that could be spelled in multiple ways (i.e., inconsistent words) typically produce longer auditory lexical decision latencies and more errors than do words with rimes that could be spelled in only one way (i.e., consistent words). These results have been ex...
متن کاملOrthographic activation in spoken word recognition Automatic activation of orthography in spoken word recognition: Pseudohomograph priming
There is increasing evidence that orthographic information has an impact on spoken word processing. However, much of this evidence comes from tasks that are subject to strategic effects. In the three experiments reported here, we examined activation of orthographic information during spoken word processing within a paradigm that is unlikely to involve strategic factors, namely auditory priming ...
