The way individuals pronounce common words like 'happy,' 'baby,' 'chilly,' or 'city' could be an indicator of their social class, according to a recent study. Researchers found that people who pronounce these words with an open 'eh' sound, as in 'happeh,' are more likely to come from working-class backgrounds. Conversely, those from middle-class backgrounds tend to use a more closed 'ee' sound, as in 'happee,' with higher social classes exhibiting a generally 'tenser' vowel sound.

These findings, published in the journal Language Variation and Change, are based on an analysis of Mancunian accents from recordings of over 100 individuals in Manchester. A remarkable aspect of the study is the remarkable stability of this linguistic difference across multiple generations. Despite significant social changes in Manchester over recent decades, the distinction in pronunciation has persisted. Teenagers as young as 16 exhibit the same class-based variations in the 'happy vowel' as their grandparents, irrespective of gender.

Dr. Maciej Baranowski, the lead researcher from the University of Manchester, stated that the research demonstrates how everyday speech can reflect enduring social patterns. While the accent differences remained stable, the study did identify some variations along ethnic lines. Mancunians of British Pakistani heritage were more inclined to use the 'happee' pronunciation, even if they were from a working-class background, whereas their white and Black Caribbean counterparts were more likely to use 'happeh.'

Another notable observation was that speakers from Manchester themselves seemed largely unaware of these subtle pronunciation differences. While most speakers tend to adopt a more middle-class pronunciation with a tenser '-ee' sound in formal speech, such as reading from a list, individuals from the lowest social class group consistently maintained their 'happeh' pronunciation. The study found no evidence of stigma associated with the working-class '-eh' pronunciation, and anecdotal evidence suggests most speakers do not consciously notice the difference in their own speech. This implies the distinction may operate below the level of conscious awareness, despite being apparent to outsiders.

Dr. Baranowski, who did not grow up in Manchester, noted that the softer '-eh' sound was a striking feature of the Mancunian accent upon his arrival in the city. However, his co-author, Dr. Danielle Turton of Lancaster University, reported being unaware of the difference until she trained as a linguist. The researchers also observed that individuals from working-class backgrounds in Manchester do not typically alter their accent based on the social context. This may be less of an issue given that research suggests the Manchester accent is among the most easily understood regional accents in the UK.

Past research indicates that accents can significantly influence perceptions and life prospects. Accents begin developing in early childhood and are largely established by age 14. Studies have shown that people can be judged harshly based on their speech. For instance, a 2023 study from the University of Cambridge suggested that Cardiff accents are perceived as kind and friendly, while Scouse accents are associated with untrustworthiness. Additionally, research from Harvard Business School identified an 'accent penalty' in high-profile settings, where speakers with non-standard accents consistently received less engagement on TED Talks, potentially hindering their career opportunities.

Further research on English accents predicts that some northern accents in England could disappear by 2066, potentially being replaced by 'posh' southeastern pronunciations. However, certain north-south pronunciation differences, such as the word 'bath,' are expected to persist.
