How pregnancy really did change Adele’s voice

A new study confirms there is such a thing as a 'mum voice' - but how and why does it happen?


Superstar singer Adele revealed that when she was pregnant with her son Angelo, back in 2012, her voice completely changed – and now a study by Sussex University has confirmed that ‘mum voice’ is an actual thing.


“In pregnancy my voice got a lot lower, which is why Skyfall is so low – I couldn’t get up that high,” she said when Angelo was around 3 years old.

The star also underwent throat surgery in 2011, which she says made her voice sound very “clean”. “I can sing a lot higher than I used to, and I can sing a lot lower,” she revealed.

What does the study say?

A recent study carried out by Sussex University has revealed that women’s voices can, in fact, fall by almost a 6th of an octave after giving birth.

The research, published in the Evolution and Human Behaviour journal, looked at 40 mums over a 10-year period and revealed that their voices became lower and more monotonous after giving birth – but that they reverted to their original pitch after 5 years.

The study cited possible reasons for the voice lowering were either tiredness or hormonal changes.

How much can the voice change?
