Research with speakers with acquired production difficulties has suggested phonetic processing is more difficult in tasks that require semantic processing. The current research examined whether similar effects are found in bilingual phonetic processing. English-French bilinguals' productions in picture naming (which requires semantic processing) were compared to those elicited by repetition (which does not require semantic processing). Picture naming elicited slower, more accented speech than repetition. These results provide additional support for theories integrating cognitive and phonetic processes in speech production and suggest that bilingual speech research must take cognitive factors into account when assessing the structure of non-native sound systems.
对有后天性发音困难的说话者的研究表明，在需要语义处理的任务中，语音处理会更加困难。当前的研究考察了在双语语音处理中是否也能发现类似的效应。将英法双语者在图片命名任务（需要语义处理）中的发音与重复任务（不需要语义处理）中引出的发音进行了比较。结果发现，图片命名任务引发的言语比重复任务中的言语语速更慢、口音更重。这些结果为将认知和语音过程整合到言语产生中的理论提供了更多支持，并表明双语语音研究在评估非母语语音系统的结构时必须考虑认知因素。
