Speech is a complex auditory signal that contains multiple layers of linguistic and non-linguistic structure, it contains both linguistic and social class information. Perceivers are exquisitely sensitive to this layered structure and extract not only linguistic properties, but also indexical characteristics that provide information about individual talkers and groups of talkers. Social class information involves inferring the speaker's social class or forming an impression of their social status based on their speech. Previous research on social class perception in speech has primarily focused on English, with relatively little research on Chinese. This study examines social class perception in Chinese speech. Study 1 employed class judgment and evaluation tasks with a subjective social class scale as the main measure to examine whether listeners could infer class information from Chinese speech and how their own class background influenced their perception. The results of Study 1 showed that subjects could accurately discriminate between speakers' social classes, but there may be a response bias that overestimates lower-class speakers as upper-class speakers. Study 2 focused on whether the speech of different classes of speakers actually differed on a number of indicators. It was found that the speech of higher class speakers was perceived to be more standardised, more pleasant to listen to and less accent-intensive. Overall, listeners can perceive class information from Chinese speech; different classes of Chinese speech do contain different levels of indexical information. In Chinese language societies, individuals can also judge their class information through the speech, which is consistent with the relevant research results in English.
