Why does my voice sound different when I speak English and French?
During a recent session with a client, we were having a conversation practicing word stress when he suddenly stopped.
“I don’t recognize my voice when I speak English. I sound like a different person.”
I asked him what he felt changed.
“I can’t really explain it, but I feel like my voice is deeper.”
He was right -- and he wasn’t imagining it. When he was speaking English, his voice was deeper.
Now, that’s not because he’s suddenly taken on a new personality, but it has everything to do with where the voice is placed in the vocal tract, causing a change in resonance.
In short -- it changes the sound of your voice. Let’s explore why.
What is vocal resonance?
Have you ever taken a moment to think about where your voice comes from or why it sounds how it sounds?
My guess is no.
Most of us talk every day without ever thinking about the sounds that come out of our mouths.
Sound starts in the vocal cords, which vibrate to produce sound waves, but the quality of the sounds is determined by the space in the vocal tract: the throat, the mouth, nose and nasal cavity. Because you can move the parts of your vocal tract independently -- tongue forward or back, jaw open or closed, soft palate raised or lowered, for example -- your vocal tract is constantly changing shape as you speak.
These changes impact how sound waves travel, creating differences in amplification and sound quality. This is your vocal resonance.
Vocal placement is how we describe where the sound vibrates in the body, for example: forward toward the lips, back in the throat, or up into the nasal cavity depending on whether the soft palate is open or closed.
Every language trains this tube into different habitual shapes. French, for example, uses the soft palate differently for its nasal vowels than English does — which is part of why the same voice can feel like it's coming from a different "place" depending on the language.
Why French tends to resonate more forward and nasally
One of the most distinctive elements of the French language is the nasal vowel phonemes built into the language.
Words like “vin”, “bon”, and “un” are pronounced with a lowered soft palate, forcing air through the nasal cavity and creating a more nasal sound. If you don’t pronounce the nasal sound correctly, you could be changing the usage and meaning of the word.
Additionally, French vowels in general tend to be created with fairly tense lips with less openness than English.
The lowered soft palate combined with the tense and closed oral posture, French is mainly placed toward the front of the mouth or in the nasal cavity, giving it a brighter timbre than a language like English.
Why English tends to sit differently -- and why it impacts your clarity
Compared to French, English resonance tends to be more in the oral cavity, making the sounds have slightly more depth.
First of all, there are more short, open vowel sounds in English that don’t exist in French. Vowels like the open /I/ in “Sit” or the open /ʊ/ in “book” aren’t in the French language and are pronounced with more relaxed lips and jaws. There’s also more space in the back of the mouth with a raised soft palate.
Secondly, nasality in English exists only when a vowel is followed by a nasal consonant. As opposed to French, the nasality lives in the consonant sound -- like in the words “sand” or “him”-- not the vowel. So, the English sounds don’t live as far forward as in French.
How this affects clarity and being understood in English
If there’s one thing I say to my French clients all the time, it’s this:
“Open your mouth!”
As mentioned, French is created in the front of the mouth with tense lips that are necessary for clarity of the sound. However, keeping this tense or more closed musculature when pronouncing English will lead to your vowels sounding thin or too nasal.
By relaxing the jaw and opening the mouth more -- especially on the open /a/ in “Cot” and /ʊ/ in “Cut” -- you’ll have a sound the vibrates more towards the back of the mouth, giving the vowels the fullness that they need in English.
Practical exercises to understand voice placement
Take a moment and “hum” with your lips closed.
You should feel a vibration right behind your nose. That’s your sound resonating in your nasal cavity.
Now, open your mouth with relaxed lips and a lowered tongue, imagining you have the space for an egg to sit between the back of your tongue and the roof of your mouth.
Say the sound “ah” as if you just learned something surprising. Make sure you keep the space for the egg!
You should feel a vibration bouncing around the back of your mouth. This is oral resonance, which is where open English vowels want to live.
Try going back and forth between the two sounds a few times to feel the difference. In doing so, you’ll start to get a sense of just how open your mouth needs to be for English.
Finding your English voice
When my client understood the placement of his English vowels versus his French habits, he became more comfortable with the deeper sound he was producing.
Knowing where English resonates compared to French isn’t about changing your voice completely. It’s about giving you the range of sound to help your English sound natural and confident.
