Why Do People Seem To Mumble?

"Why Doesn't Anyone Speak Clearly Anymore?"

It's a surprisingly common complaint.

"Everyone seems to mumble."

You might hear somebody speaking perfectly well, but certain words disappear. You ask them to repeat themselves and, frustratingly, the second time you understand them.

Perhaps television dialogue isn't as clear as it used to be. Conversations across a room are difficult. Restaurants are particularly challenging. You may even find yourself thinking younger generations simply don't speak as clearly.

Sometimes people genuinely do mumble.

But when everyone appears to have started mumbling, there may be something else going on.

Hearing Speech Is More Complicated Than Hearing Sound

Speech contains an enormous amount of information.

Some speech sounds are naturally louder and easier to hear, while others are much softer and more subtle.

If parts of speech become harder to detect or distinguish, you may still hear someone's voice but lose some of the information needed to understand individual words.

Your brain then tries to fill in the gaps using context.

For example, you may hear most of a sentence but miss one or two crucial sounds. In a quiet room, your brain may successfully work out what was said.

Add a television, other conversations or restaurant noise and suddenly there isn't enough information available.

The result?

It sounds like mumbling.

Why Is It Worse In Background Noise?

In quiet surroundings there is very little competing with the speaker.

In a busy environment, the voice you want to hear has to compete with:

• Other conversations.
• Traffic.
• Music.
• Air conditioning.
• Kitchen noise.
• Television.
• Reverberation and echoes.

Your brain has to separate the important speech from everything else.

For people with hearing loss, auditory processing difficulties or age-related changes in speech processing, this can require considerably more effort.

Distance Matters Too

Imagine someone speaking to you from the other side of a restaurant table.

Their voice may be perfectly clear when you're sitting next to them.

Move them two metres away, add conversations from neighbouring tables, background music and the clatter of plates, and the listening situation changes completely.

This is why simply increasing hearing aid volume isn't always enough.

The problem may be clarity, rather than volume.

Could It Be Hearing Loss?

Possibly.

One of the earliest signs of hearing difficulty can be struggling to understand speech, particularly in background noise.

People sometimes assume hearing loss means everything becomes quieter.

In reality, you may continue hearing many sounds perfectly well while particular elements of speech become harder to distinguish.

If you've noticed a persistent change in your hearing or speech understanding, having your hearing assessed is sensible.

But hearing loss isn't the only possible explanation.

What If My Hearing Test Is Normal?

This is where things become particularly interesting.

Some people have hearing levels considered normal on a standard hearing test yet experience genuine difficulty understanding speech.

You may struggle with:

• Background noise.
• Multiple speakers.
• Fast conversations.
• Distance.
• Accents.
• Following meetings.
• Listening for long periods.

Auditory processing differences, ADHD, autism and other factors can influence how easily the brain selects, processes and follows speech.

Listening ability therefore exists on a much broader spectrum than simply "normal hearing" versus "hearing loss".

Technology Can Help Improve The Signal

If the problem is speech clarity, one approach is to improve the quality of the speech reaching the listener.

Remote microphone technology does this by placing the microphone closer to the speaker.

Phonak Roger On V3

Roger On captures speech close to its source before transmitting it to compatible hearing aids or Roger receivers.

It can be used in several different ways depending on the situation.

Place it on a table during a meal or meeting, wear it using the lanyard for one-to-one communication, or use its pointing function to focus on a particular speaker.

This makes it particularly useful for people who struggle in:

• Restaurants.
• Meetings.
• Family gatherings.
• Lectures.
• Social events.
• One-to-one conversations in noise.

Instead of simply increasing the volume of everything around you, the system helps improve access to the speech you actually want to hear.

For One-To-One Conversations

Phonak PartnerMic

For compatible Phonak hearing aid wearers, PartnerMic provides a simple solution when one particular person's voice needs to be heard.

The microphone is worn by the other person and their voice is streamed directly to the hearing aids.

This may be particularly useful for couples who find conversations increasingly difficult when walking, travelling or spending time somewhere noisy.

If You Don't Wear Hearing Aids

You don't necessarily need to be a hearing aid wearer to benefit from technology designed to make speech easier to access.

For people who experience significant listening difficulties despite normal or near-normal hearing, Roger On can be combined with Roger Focus receivers.

For those wanting more occasional, situational assistance, Nuance Audio Hearing Glasses provide another interesting option.

Directional microphones incorporated into the eyewear help enhance sounds in front of the wearer, making them particularly suited to conversations, restaurants and social situations.

This may appeal to someone who generally hears well but increasingly finds certain environments challenging.

Don't Just Ask People To Speak Louder

When someone sounds unclear, our natural reaction is to ask them to speak up.

But louder isn't necessarily clearer.

It can be more useful to ask someone to:

• Face you.
• Speak slightly more slowly.
• Speak clearly rather than shouting.
• Reduce the distance between you.
• Move somewhere quieter.

Reducing competing noise can sometimes make a surprisingly large difference.

Perhaps Everyone Hasn't Started Mumbling

If one person mumbles, they may well be mumbling.

If everyone appears to mumble - at home, on television, in restaurants and during meetings - it's worth exploring why.

The answer may involve hearing, auditory processing, the listening environment or a combination of factors.

Most importantly, you don't necessarily have to accept it as part of getting older or withdraw from situations you previously enjoyed.

Understanding why speech has become difficult is the first step towards finding a solution that makes conversations clearer again.
