Why Does My Voice Sound Fine to Me but Quiet to Everyone Else?

"Can you say that again?"

"Speak up a bit."

"I can't hear you."

If you have Parkinson's disease, these comments may sound very familiar.

Perhaps your spouse asks you to repeat yourself several times a day. Maybe your grandchildren struggle to hear you. You may even find yourself avoiding phone calls because people constantly ask you to speak louder.

What can be confusing is that your voice sounds perfectly normal to you.

You may feel like you are speaking at a reasonable volume.

So why does everyone else think you are talking quietly?

The answer lies in the way Parkinson's disease can affect both your voice and your awareness of how loud you are speaking.

A Common Symptom of Parkinson's Disease

Many people are surprised to learn that changes in voice and communication are among the most common symptoms of Parkinson's disease.

In fact, it is estimated that a large number of people with Parkinson's experience changes in their speech at some point.

Common changes include:

• A quieter voice

• Mumbling or unclear speech

• Speaking too quickly

• A flat or monotone voice

• Difficulty being heard in noisy places

• Running out of breath while speaking

These changes often develop gradually over time.

Because the changes happen slowly, many people do not notice them straight away.

Family and friends are often the first to spot the difference.

"But I Feel Like I'm Speaking Normally"

This is where things become frustrating.

Many people with Parkinson's genuinely believe they are speaking at a normal volume.

They are not deliberately speaking quietly.

The problem is that Parkinson's can affect how the brain processes information about movement and effort.

The brain starts to misjudge how much effort is needed to produce a strong voice.

As a result:

• A voice that sounds normal to you may sound quiet to everyone else.

• Speaking loudly may feel like shouting.

• Increasing your volume can feel uncomfortable at first.

This reduced awareness of voice volume is one of the hallmark communication changes seen in Parkinson's disease.

Why Does Speaking Louder Feel So Strange?

Imagine wearing sunglasses every day.

Over time, your brain adapts to the darker view.

When you take the sunglasses off, everything suddenly looks very bright.

Your eyes have adjusted to a different normal.

Something similar can happen with voice volume in Parkinson's disease.

Your brain adapts to hearing your quieter voice as normal.

When someone asks you to speak louder, it can feel as though you are shouting, even when you are simply reaching a healthy speaking volume.

This mismatch between perception and reality is why family members and partners often become frustrated.

One person feels they are speaking normally.

The other person struggles to hear them.

Neither person is wrong.

They are simply experiencing the same conversation differently.

The Impact on Daily Life

A quieter voice can affect much more than communication.

It can affect confidence, independence, and social life.

Many people begin to:

• Avoid busy restaurants and cafés

• Speak less in group conversations

• Stop making phone calls

• Let their partner speak for them

• Withdraw from social activities

Over time, this can lead to frustration and isolation.

People often tell us:

"What's the point in joining the conversation if nobody can hear me?"

Or:

"I used to enjoy meeting friends, but now I spend most of the time repeating myself."

The emotional impact of voice changes should never be underestimated.

Can Anything Be Done?

Yes.

One of the biggest myths about Parkinson's disease is that voice changes are something you simply have to accept.

The good news is that speech and language therapy can help many people improve the strength and clarity of their voice.

Research has shown that the voice responds well to targeted therapy, particularly when intervention happens early.

What Is LSVT LOUD®?

LSVT LOUD® is a specialised speech treatment designed specifically for people with Parkinson's disease.

The programme focuses on one simple but powerful goal:

Thinking loud.

Rather than teaching complicated speech techniques, LSVT LOUD helps retrain the brain's understanding of what a healthy voice sounds and feels like.

People learn to:

• Use a stronger voice

• Improve vocal loudness

• Speak more clearly

• Increase confidence in communication

• Carry these improvements into everyday conversations

Importantly, the aim is not to make people shout.

The goal is to help them achieve a voice volume that others can hear comfortably.

Why Early Action Matters

Many people wait until communication has become a major problem before seeking help.

However, voice changes often respond best when addressed early.

If family members have started asking you to repeat yourself more often, or if you are beginning to lose confidence in conversations, it may be worth seeking advice sooner rather than later.

Addressing communication difficulties early can help people stay active, social, and engaged in the activities they enjoy.

The Bottom Line

If your voice sounds normal to you but quiet to everyone else, you are not imagining things.

This is a common communication change associated with Parkinson's disease.

The good news is that support is available.

Understanding why it happens is the first step.

The next step is recognising that voice changes are not something you simply have to put up with.

At Speech Therapy Glasgow, we support people living with Parkinson's disease to improve communication, maintain confidence, and stay connected with the people and activities that matter most.

Because being heard is about more than volume.

It's about staying part of the conversation.
