目的平均发音率 (MAR) 是测量发音率的另一种方法，定义为在感知流畅、无停顿的语音中，最少 10 个到最多 20 个连续音节的 5 个速率测量值的平均值。这项研究检验了这种方法的有效性。方法阅读和自发言语样本是从 80 名年龄在 20 岁至 59 岁之间、通常流利的成年人中收集的。拼字转录后，所有样本首先使用流行的“全局”方法进行发音率分析，该方法考虑整个语音样本并涉及对语音样本的操作，然后再次应用 MAR 方法。配对样本t进行测试是为了将全球测量值与 MAR 测量值进行比较。结果对于自发言语和阅读，两种方法之间存在很强的相关性。然而，对于这两个语音任务，配对样本t测试显示存在显着差异，MAR 值高于全球方法值。结论MAR方法是衡量衔接率的有效方法。但是，它不能与流行的全局方法互换使用。在建议一般临床使用之前，需要对 MAR 方法进行进一步标准化。

Measuring Articulation Rate: A Comparison of Two Methods

Purpose Mean articulatory rate (MAR) is an alternative approach to measure articulation rate and is defined as the mean of 5 rate measures in minimally 10 to maximally 20 consecutive syllables in perceptually fluent speech without pauses. This study examined the validity of this approach. Method Reading and spontaneous speech samples were collected from 80 typically fluent adults ranging in age between 20 and 59 years. After orthographic transcription, all samples were subjected to an articulation rate analysis first using the prevailing “global” method, which takes into account the entire speech sample and involves manipulation of the speech sample, and then again applying the MAR method. Paired-samples t tests were conducted to compare global measurements to MAR measurements. Results For both spontaneous speech and reading, a strong correlation was found between the 2 methods. However, for both speech tasks, the paired-samples t tests revealed a significant difference with MAR values being higher than the global method values. Conclusions The MAR method is a valid method to measure articulation rate. However, it cannot be used interchangeably with the prevailing global method. Further standardization of the MAR method is needed before general clinical use can be suggested.
