Starting in the 1980s, proper Cantonese pronunciation has been much promoted in Hong Kong, with the scholar Richard Ho (何文匯) as its iconic campaigner. The very idea of "proper" pronunciation of Cantonese Chinese is controversial, since the concept of labeling native speakers' usage and speech in terms of correctness is not generally supported by academic linguistics. Law et al. (2001) point out that the phrase "lazy sounds" (懶音 laan5 jam1), most commonly discussed in relation to phonetic changes in Hong Kong Cantonese, implies that the speaker is "unwilling to put forth sufficient effort to articulate the standard pronunciation".
