本报告回顾了有关年龄较大儿童和成人语音错误的出现和流行的现有文献。来自多个不同来源的调查结果表明，总体上 1% 到 2% 的年轻人可能会出现这些错误。高达 75% 的这些错误可能会在发育期结束（即 9 岁）和高中结束之间自行解决，尽管言语治疗服务可能仍然有理由减少这些错误的任何负面社会后果。假设这些误差至少有两个不同的来源。残余语音错误（两种类型中更常见的一种）似乎是早期语音延迟的遗留问题，最初是遗漏或替换错误，但后来逐渐接近正常，变成了扭曲。另一方面，持续的言语错误似乎是从小就出现的扭曲，反映了长期形成的习惯。目前尚不清楚这种区别是否表明对特定干预措施有不同的反应，或者这两种类型是否更有可能或不太可能自发解决。
This report reviews the existing literature on the emergence and prevalence of speech sound errors in older children and adults. Findings from several different sources suggest that 1 to 2% of the young adult population overall may present with these errors. Up to 75% of these errors may resolve on their own between the end of the developmental period (i.e., age 9 years) and the end of high school, though speech therapy services may still be justified to reduce any negative social consequences of these errors. At least two different sources of these errors are postulated. Residual speech errors (the more common of the two types) appear to arise as a leftovers from a much earlier speech delay and were originally omission or substitution errors but migrated closer to normal to become distortions. Persistent speech errors, on the other hand, appear to be distortions from an early age that reflect long-instantiated habits. Whether this distinction points to different responses to particular interventions, or whether either type is more or less likely to resolve spontaneously is not clear at this time.
