When speaking to someone on the phone, you might have a vague image of their age before meeting them. Watching old footage and being more surprised by the change in voice than the face—isn't that an experience you've had?
We imagine a person's age and character from the pitch, resonance, and manner of their voice. However, these clues do not always match their date of birth.
An interesting example analyzed by linguists is Madonna.
According to a study introduced by Phys.org on October 6, 2026, her speaking voice is difficult to explain solely by the changes generally expected with female aging. Her voice, which was low in her youth, sometimes became higher in later years. Additionally, her vowel pronunciation did not neatly fit the characteristics of her generation or region of origin.
Could it be that the artist, who has continuously changed her costumes, music, and stage performances, has also shaped how she is perceived through her voice?
The focus was not on hit songs, but on her speaking voice in interviews
The research was conducted by researchers from Aarhus University and the University of Copenhagen in Denmark. The paper, "The Age Chameleon: Social and Biological Effects on Madonna’s Ageing Voice," was published in the academic journal Nordic Journal of English Studies.
The analysis covered interviews spanning approximately 40 years, from the 1980s to 2021.
This is a key point to understand when reading this news. The focus was not on the singing voice recorded on albums or her vocal ability in concerts. It examined changes in the pitch of her speaking voice and vowel pronunciation in interviews.
In other words, this study did not prove that "she can still hit high notes like before," "her vocal ability hasn't declined," or "she doesn't process her voice in music production."
The researchers focused on the discrepancy between the age and regional characteristics that should be etched into her voice and the actual audio.
Her voice did not simply become lower with age
The study introduction explains that women's voices tend to become lower due to physical changes associated with menopause, involving changes in the vocal cords and surrounding muscles.
However, this is a general trend and does not mean everyone changes in the same way at the same age.
In Madonna's case, around 2013, when she was 55, a change to a lower voice was observed. The researchers noted that this period roughly coincides with the typical age of menopause.
However, in the following years, her voice pitch rose again.
Moreover, looking over the entire analysis period, some of the times when a low voice was recorded were in the 1980s when she was still young. On the other hand, from the late 1990s onwards, there was a general trend of her voice becoming higher.
The change cannot be depicted with a single line of "the younger, the higher; the older, the lower."
The researchers suggest that she may have actively adjusted her voice. Just as she chooses costumes for each stage and changes expressions for each work, her speaking voice might also have been part of her self-expression.
"Intentionally changed" is an interpretation, not a confirmed fact
Here, it is necessary to separate the observed results from the speculation about their reasons.
The change in voice pitch over time is a result obtained from acoustic analysis. However, the purpose for which she might have changed her voice cannot be determined by the same analysis alone.
The study introduction mentions the possibility of the influence of hormone therapy in addition to conscious voice adjustment. However, it is not a report confirming that Madonna actually underwent such treatment, nor does it specify her menopause period.
Therefore, this study cannot be reinterpreted as "the secret to Madonna's youthful voice was hormone therapy."
The research team does not claim that the possibilities they listed can fully explain the complex changes over about 40 years. What is interesting is not that a single cause was determined, but that the changes in her voice could not be explained solely by the body's age.
Vowels also showed characteristics that did not fit her birthplace or generation
The analysis did not stop at just the pitch of her voice.
The researchers also examined the pronunciation of vowels found in English words like "trap," "dress," "kit," "lot," and "thought." These vowels serve as clues when considering regional differences and changes in pronunciation in English.
However, Madonna's pronunciation did not simply match the changes seen in the way people from Michigan, where she was born and raised, or New York, where she lived in her youth, or her generation spoke.
Moreover, over time, the acoustic differences of several vowels expanded, and some vowels showed a change towards a more fronted pronunciation.
Technically referred to as "expansion of the vowel space," this does not mean the inside of the mouth physically became wider. It means that when the acoustic characteristics of vowels are plotted, the distance between vowels expanded.
Researchers point out that these pronunciation characteristics might be perceived as associated with youth and attractiveness. However, it is not a universal rule that a specific pronunciation will sound attractive to everyone.
How a sound is perceived also involves the listener's familiarity with the language and social image.
Debate on SNS about "voice processing" and "women's age"
In the range of public posts confirmed this time, it was not possible to gather sufficient SNS reactions to the study itself. Meanwhile, discussions among fans about Madonna's voice and aging have continued independently of the study introduction.
In the Madonna-related community on the English-speaking bulletin board-style SNS "Reddit," there is a post titled "Vocal Comparison." The poster favorably evaluates the voices heard in "Popular" and "Vulgar," while questioning why the impression of voice processing differs between works.
Comments also show an understanding of artists adjusting their expression and singing style as they age.
However, these are listener impressions and speculations. They are not materials that verify the degree of processing or production intent. Also, discussions about the singing voice in songs cannot be directly used as a rebuttal to this study, which deals with the speaking voice in interviews.
Another thread on Reddit worth noting highlights a video of Madonna speaking about ageism when she was younger.
There, comments were made about the contradiction of expecting women to "age naturally and gracefully" while simultaneously expecting a youthful appearance. Some voices question whether even the compliment "you haven't changed at all" strengthens the pressure to maintain youth to be valued.
These are not the consensus of SNS as a whole. Nevertheless, it is evident that the topic of her aging is linked not only to preferences for her voice and appearance but also to discussions about what society expects from women.
In Japan, too, we should consider the expectation of "age-appropriate voice"
When Japanese readers take in this study, the interest lies not only in Madonna's uniqueness.
In Japanese, phrases like "your voice sounds young" or "you have a calm voice" are used. Both can be compliments, but behind them is a sense of expecting a certain combination of age and voice.
For example, when answering the phone, explaining at work, or chatting with friends. Even the same person may change the pitch of their voice, the speed of their speech, and their choice of words. It reflects the relationship with the other person and how they want to behave in that situation.
This study provides material to consider the relationship between voice and self-expression over a long period.
However, the results regarding English vowels cannot be directly applied to the Japanese "a, i, u, e, o." Also, the results of analyzing one celebrity cannot explain the voice changes of all people.
Still, it could be an opportunity to notice the listener's preconceived notion of "at this age, it should sound like this."
Being perceived as young is not the only value of a voice
The fact that Madonna's voice did not fit the characteristics expected from her age is an intriguing discovery. However, if this becomes a new standard of "the younger the voice, the better," the discussion becomes narrow.
The lower resonance and calmness that come with age can also become part of a person's expression. Accepting changes and adjusting one's voice for expression are not things others can uniformly decide as correct.
What this study suggests is that a person's voice encompasses not only physical changes but also interactions with society and self-expression.
Trying to classify Madonna's voice as "appropriate for her age" does not fit neatly. This very misfit might be another clue to consider her resistance to having the scope of expression determined by age.
