与阅读或实验室语言不同，自发语言包含高频率的不流畅（例如重复，修复，填充停顿，错误开始）。本文旨在提高“不流利意识”，特别是在语音学领域，这对增加我们对这些现象的理解有很大的帮助。本文通过对不同语料库中自发性美语语音不流畅现象的分析，提出了两大观点。首先，生态学主张认为，语言不流畅与其产生的说话环境的各个方面有关。这一说法得到了任务效应、位置分析、说话者效应和社会语言学效应的支持。其次，一项声学主张认为，不流利会对语音的语音和韵律方面产生影响，而这些方面在实验室语音的语音模式中没有得到体现。这些影响包括片段持续时间、语调、语音质量、元音质量和协同发音模式的改变。生态和声学证据提供了在现实环境中人类语言生产的见解。这些证据也可以指导自动语音识别应用中自发语音的处理方法。
Unlike read or laboratory speech, spontaneous speech contains high rates of disfluencies (e.g. repetitions, repairs, filled pauses, false starts). This paper aims to promote ‘disfluency awareness’ especially in the field of phonetics –which has much to offer in the way of increasing our understanding of these phenomena. Two broad claims are made, based on analyses of disfluencies in different corpora of spontaneous American English speech. First, an Ecology Claim suggests that disfluencies are related to aspects of the speaking environments in which they arise. The claim is supported by evidence from task effects, location analyses, speaker effects and sociolinguistic effects. Second, an Acoustics Claim argues that disfluency has consequences for phonetic and prosodic aspects of speech that are not represented in the speech patterns of laboratory speech. Such effects include modifications in segment durations, intonation, voice quality, vowel quality and coarticulation patterns. The ecological and acoustic evidence provide insights about human language production in real-world contexts. Such evidence can also guide methods for the processing of spontaneous speech in automatic speech recognition applications.
