“…Recently, several studies have been conducted on European languages and on Chinese dialects, for example, (Gooskens and Heeringa, 2004;Heeringa, 2004;Tang and Heuven, 2007;Tang and Heuven, 2009;Tang and Heuven, 2015) by employing the Levenshtein algorithm together with the mutual intelligibility and perceptive distance measures. For instance, Gooskens (2007) (Gooskens and Heeringa, 2004;Tang and Heuven, 2007;Tang and Heuven, 2009). According to Gooskens (2013), functional intelligibility between related languages can be measured by employing content questions, translation, recorded text testing, observations and performance tasks.…”
