New mothers’ voices drop by more than one piano note after pregnancy, new research suggests.

This is only temporary with most women’s voices being back to normal a year after giving birth, a study found.

Scientists believe women’s voices become deeper after having children in an attempt to sound more authoritative as new parents, shares Daily Mail.

Lead researcher Dr Kasia Pisanski, from the University of Sussex, said: ‘Research has already shown that people with low-pitched voices are typically judged to be more competent, mature and dominant, so it could be that women are modulating their own voices to sound more authoritative, faced with the new challenges of parenting.’

Voice changes may also be driven by hormone fluctuations

Singer Adele claims she sounded ‘like a man’ while pregnant, which she credits for helping her to hit the low notes in the Oscar-winning James Bond theme song Skyfall, adding ‘these days I do struggle to get down there’.

Actress Kristen Bell, who voiced the character of Anna in the Disney hit Frozen while expecting her daughter Lincoln Bell Shepard, reportedly had to to re-record some of her lines due to her deep voice.

Dr Pisanski said: ‘Our results show that, despite some singers noticing that their voices get lower while pregnant, the big drop actually happens after they give birth.

‘One possible explanation is that this is caused by hormone changes after childbirth.

‘We know that after pregnancy, there’s a sharp drop in the levels of key sex hormones, and this could influence vocal fold dynamics and vocal control.’

Did you notice a change in your voice during or after pregnancy?
