New research suggests that accents can impact advert effectiveness 

IRS+ conducted an experiment to explore Local Accent Bias, showing that consumers were more engaged when an ad featured an accent similar to theirs

Response to a Nissan car commercial featuring a local voiceover was up to 5.13% higher than the response to the same ad with a neutral voiceover.

New research suggests that voiceover accents can impact the effectiveness of advertisements.

Broadcast advertising specialists IRS+ conducted an experiment with 15,000 respondents to explore the psychology behind the commercial impact of accents.
