A recent model of temporal control in speech holds that speakers use sensory feedback to control speech rate and articulatory timing. An experiment was conducted to assess whether there is evidence in support of this hypothesis by comparing durations of phrases in external speech (with sensory feedback) and internal speech (without sensory feedback). Phrase lengths were varied by including one to three disyllabic nouns in a target phrase that was always surrounded by overt speech. An inferred duration method was used to estimate the durations of target phrases produced internally. The results showed that internal speech is faster than external speech, supporting the hypothesis. In addition, the results indicate that there is a slow-down associated with transitioning between internal and external modes of production.
最近有一种关于言语时间控制的模型认为，说话者使用感觉反馈来控制语速和发音的时间。通过比较外部言语（有感觉反馈）和内部言语（无感觉反馈）中短语的持续时间，实验评估了这个假设是否有证据支持。通过在目标短语中包含一个到三个双音节名词来改变短语的长度，而目标短语总是被明显的言语所包围。使用推断持续时间法来估计内部产生的目标短语的持续时间。结果表明，内部言语比外部言语快，这支持了假设。此外，结果还表明，在内部和外部生产模式之间转换时会出现减速。
