This web is to show people that despite fact that many others are saying that is good  to agree,

              to accept and to put your head down in front of your stutter - which I disagree with that.                                              



                             What is good and worth it's to fight your stutter and never give up 

           I'm MATT TOMZAK - Inventor of App 2beFluent.

        This App is new digital Invention, to help stutterers

                                     to speak fluent.




App                  is my method to combat with           .   

My name is Matt Tomzak and I stutter myself for 43 years.

I know exactly how you're feeling as stutterer right now.

So many times I have had speech therapy of which none really helped except one I had 20 years ago.

However my speech has improved to 80 % only and I haven’t gained the 100 % fluency I wanted.

After not long time some of my stutter came back and fluency of my speech it did vary between 55 - 80 %.

It was constant " fight " to speak with most fluency as possible.

I know that stutter tends to come back when certain circumstances fulfill, that did happen in my case. 

Instead of refresh my speech therapy I made a choice that for the next 13 years I'd look for a solution to help me become 100 % fluent.


By manipulating sound I found a solution to make it possible to make me Fluent.

What most important to stop feeling blocks while speaking to others and be able to speak 100 % natural.

Without constant " attention " to fulfill all elements learned on speech therapy I had before.

This was important for me as I don't accept unnatural speech even if it's 100 % fluent.


This sound effect 2beFluent  is created to my own spec in certain classified and unique ways and it varies from other sound effects used to combat stutter.


My sound effect 2beFluent isn't available elsewhere it is my own unique sound effect.


I'm Inventor & I'm designer & I'm 1st “guinea pig” of this sound effect.

This unique sound effect I call TAAF (Tomzak Altered Auditory Feedback) is designed to recreate a “choral speech effect”.

When I use the TAAF sound effect I can hear myself in earphones ( while I'm talking into the microphone ) with a delay & strength of the signal, which can be regulated by myself.


What I find special is that my sound effect makes me calm and relaxed when I speak. Even when I'm supposed to speak and I'm nervous when I hear my

" modified " voice in App 2beFluent this makes me more calm and any blocks which maybe seen on horizon they disappear. 


When I use my App 2beFluent and I follow my guidelines blocks go away, what means I'm free of blocks what makes me fluent.

There is one very important ( crucial ) rule it must be fulfilled during use of my Invention, stutterer must slow down his speech. So he must hear his voice to go with the same speech tempo with this one he will hear in earphone like in choir speech, not to be ahead of it, but to with it. If he won't slow down his speech in satisfactory level the idea won't work or will work in partially strength only.

I used this sound effect for last 2 years on myself and it helps me to be fluent when I use it.

My tests with other stutterers have had positive results, in many cases there were immediate reductions of stuttering.

I'm quite confident that you can also become more fluent as me.

I must emphasize this is not a " magic pill " which makes you fluent when you take it.

To start to make the task of fluency possible in the long term, you have to work on your speech whilst you are fluent. App 2beFluent can make you more fluent so you can work further on your speech.


We need to start at some point to help you right now by using this tool, which I have designed and created for myself.

Now you have a chance to try it.


When you will use my App 2beFluent you must also work on your speech and I'll ask you to fully follow my advice.

If you won't fully follow my advice when you use my App 2beFluent the effect may not work or may not work correctly as it should.

My idea is that App 2beFluent will work in any incl. " difficult " situation.

App 2beFluent you'll have with you all the time, but it depends only from you if and when you'll use it.

In some situations you may decide that you don't need it.

I'm doing just like that, sometimes I'm using App 2beFluent often, and sometimes I'm not using App 2beFluent at all.

When I offer you my App 2beFluent this is start of my method by giving you a tool to combat your stutter.

The long term plan is to constant develop & adjust my method. Your experience with App 2beFluent will be priceless for me.

Please contact me after you purchase App 2beFluent as I'd recommend online lessons face to face that I'd be able to pass on my experience & know​ledge – on how to use it. It is very important to use App 2beFluent in correct way.

When I did mention in my above text about you must also work on your speech.

If you didn't hear about it yet please watch this movie and start to exercise. Using my App2beFluent should be natural incl. breathing technique however I believe that in short ( more ) and in long ( less ) term this kind of Diaphragmatic Breathing Technique exercises will help you 2beFluent - to speak fluent.

I believe that spontaneous fluent without blocks speech comes in pair with to have calm inside you - in my theory this is one of " puzzles " you need for to speak fluent.

I'd suggest that you may listen to some recordings :

a) there were tests App 2beFluent on another persons with stutter. 

You can hear what was recorded " test of App 2beFluent with person with moderate stutter " - 3 min. Person with ( moderate ) stutter in his everyday life, guy ( in his 50s ), stuttering for ca. 45 years. In this recording ( his 1st test with App 2beFluent ) he speaks with his normal tempo speech, he speaks without to be prepared in any way to say any text nor reading any text, just natural spontaneous speech. As you can hear there are no blocks, no repetitions, no prolongations, he speaks in his own intonation, no artificial feel of sound of his speech, we can hear just his fluent natural speech including some little naturally sounded pauses. Normally without App 2beFluent he probably wouldn't say fluent even 1 sentence. Situation was normal ( low stress ), during his speech there were above 10 people present in room including 2 guest ( me and another person ) visiting for 1st time. 

b) there is recording ( 1.46 min. ) of my speech with stutter, I was talking over the phone with someone else close to me, there was no rush, no much stress, just casual talk about what are plans for next morning. Whole phone conversation took few minutes, I had cut out my ( a bit ) more fluent speech ( not much I must say ) and someone else speech. What's left you can hear now - my old speech with stutter. If I wouldn't take risk to go through ( hard ) speech therapy 20 years ago and after to work ( a lot ) on my speech I were probably sound today ( in 2019 ) as on this recording. My new speech I use for last 20 years you can hear when you look watch my movies on my YouTube channel : Matt Tomzak  ( link above ) when I talk about my Invention App 2beFluent.

App 2beFluent tests ( 2019 ) :

a) We did try on 7 people, in 2 cases it took their stutter to nil. In another 1 case ( heavy stutter ) took down stutter down significant ca. 70 % - there was problem to start speech at all as person had heavy blocks before started talking but we got over it.

In couple another cases it took their stutter a down 50 % ( these people had problem with to slow down their speech ).

1 person said it makes even worse, however she added she had neurosurgery in past which went wrong.

Speech therapist who was present on test called using App 2beFluent " warm ( safe ) hat " when they put headphones on their head and they stuttered much less ( or not at all ) as before.

b) There were 3 people with stutter.

We did try on boy ( medium stutter & medium or some heavier blocks ), there was a bit problem with slow down his speech and keep slowed for all the time we did test, but we did it, and he started to speak fluent : " can you say in % about how you had feel relaxed ? " 

He said : " 25 %". 


With girl ( light stutter ), very fast talker, she did not stutter from 1st view ( I didn't hear or see stutter at all ).

She said : " I usually don't stutter while I'm out of my house, I have problem with stutter when I'm home while I'm talking to my family ".

It wasn't straight away we managed to slow down her speech, but we did it, and we received 100 % fluency.

I had asked her question : " did you feel any relief while talking with 2beFluent ? any relaxed feeling ? can you describe in % ? and she answered : " I felt much relaxed, like 75 % improvement ."

Guy with ( severe stutter & heavy blocks ), we did try, there was huge problem to start talking at all as his blocks and to slow down his speech.

He said : " I don't enjoy speaking with this Speech aid, I used to use DAF apparatus in past. Also I had Speech therapy in past which wasn't success full and I don't recollect that therapy well, I'd like to finish this test now ".

Speech therapist who was present said :

" any device, any help, anything to help these people ( with stutter ) to talk fluent for any period of time is most welcome by us Speech therapists to allow , to help us to work with those people ".

c) The girl ( moderate stutter ) she was a very fast talker and we had some problems with slow down her speech to correct level. But we managed it and she started to talk much more fluent.

I may say improvement was ca. 80 - 90 %.

I did ask her at the end : " did you feel relaxed while using App 2beFluent ? did you feel any relief ? ". She answered : " yes, I felt much more relaxed, however I still felt some tension in my neck while talking ".

Speech therapist who was presented commented : " we can work on tensions in muscles, that's no problem ".

d) That guy had ( a bit ) stutter, it was little and hardly noticed.

After some instruction he slowed his speech very nicely, his stutter went away and improvement was significant - 100 % fluency.

At the beginning it was a bit tricky to keep his slowed speech as naturally he speaks fast, but it was possible.

e) There were 8 people with ( mild, moderate, severe, very severe ) stutter.

3 Guys ( moderate stutter ) there was little problem to reduce their speech tempo and to keep them to speak slower, but no big difficulties. Very good improvement reduce 75-90% of their stutter and completely reduction of their blocks.

Girl ( very severe stutter - very long blocks before she could start talk and heavy blocks during speech ).
When we had started using my App 2beFluent it helped her continue talking.

According to her stutter level  there was  35 % - 45 % improvement.

2 guys ( moderate stutter ). There was difficulty to slow down their speech, unfortunately they didn't listen to me much ( completely ignored my advice ). There was reduction in their stutter 50 % - 70 %.

Girl, her speech tempo was slowed down beautifully by herself ( with my very little help at the beginning ), with her it was 100% fluency improvement.

Guy ( mild stutter ) he was very good too, however he was after speech therapy and he could slow down his speech tempo ( and keep it ) without problem. His improvement 100 % fluency.

All 8 people on test except last guy were using their learned over there speech therapy which was " Rhythmic speech ".

I saw those 8 people ( apart from one ) all were knocking rhythm with their hand

( using fingers ), sounded like haltingly rhythmic artificial talk. 

These two : " Rhythmic speech " and my App 2beFluent they don't go well together, rather they are opposite 180 degrees from each other.

Speaking with App 2beFluent should be natural, spontaneous, calm. 

My experiment ( July 2019 ) about using my 2beFluent “ TAAF “ sound effect which is AFF efect and “ old fashioned DAF “ sound effect which is also AAF effect :


I receive questions about my Invention App 2beFluent, some people try to compare and make opinion that my App 2beFluent “ TAAF ” effect it isn't something different to old fashioned DAF effect.

Personally I have negative opinion about DAF effect I know it doesn't work for people with stutter at least in long ( more then couple of months ) term.

Overall effectiveness of DAF effect is very dubious.

I used to have and I used 3 DAF apparatuses, between 1983 – 1994.

There was ( when using DAF ) no improvement to fluency of my speech.

Regarding my experiment I had decided to use both effects at same or very close to each other times while I was shopping in Shopping Center.

I did use 2 languages Polish and English alternatively. There wasn't difference in App 2beFluent effectiveness regarding to the language I had used.

In one ear I had earphone with my App 2beFluent "TAAF" effect. In my another ear I had earphone with DAF effect.
Sometimes I did talk and I heard myself simultaneously in both ears with 2 different effects ( my Invention “TAAF “ effect and DAF effect ).
Sometimes I did talk and I used one earphone alternatively with another one. So, ones my Invention effect and afterwards DAF effect.

When using earphone with my Invention “ TAAF “ effect I felt relaxed, calm, and even when I felt inside about some block could be coming, or it will come right now my fear against block disappears when I was starting to talk and to hear myself.

And with earphone with DAF effect I had hear my delayed speech however I didn't feel anything special, just flat to my emotions sound - no relaxation, no calm, nothing to feel more secure against coming blocks.

Sound effect ( DAF ) did help ( a bit ) to my stutter but it was irrelevant for my emotions.

I did feel like I was left alone me and my blocks and I didn't feel secure while I was talking.

Any conclusions about mentioned effects I'd leave to yourself.


Some history about me and my Invention App 2beFluent :


This story is about me and about my invention for people with stutter.
I'm Matt and I stutter myself, I did start 43 years ago.

I believe I have created something truly unique, originally it was designed to help myself, however the idea now is to help others too. 

7 years ago with about to begin to get depression and while considering what will be with my speech in my life, a bit by coincidence, more because I was so desperate to improve fluency of my speech and move on with my life I found that some manipulated sound effect is helping me to speak fluent and I'm relaxed at the same time. 1st tests were done on myself, for few weeks I used to call my friend every day to talk for 20 minutes to see if that effect still holds me talking well ? And yes, it did.

What I have created is manipulated in specific way sound effect which I couldn't find elsewhere.
This is not DAF ( Delayed Auditory Feedback ) effect device, nor effect similar to other effects / devices available on the market already.

 My idea has started from scratch, from nothing, from blank page. My effect was designed by myself to help myself to overcome my stutter and be able to keep my speech tempo slower, as I have problem to speak faster and faster like Ferrari on motorway with glued gas pedal to the floor.

When I had created my effect I didn't want to look backwards on DAF because I knew DAF effect isn't helping ( I used to use them long time ago in late 80-ties/ early 90-ties ). I had 2 such DAF apparatuses.
From 1st view my effect could be mistaken with DAF, operating principle looks similar to DAF effect. 

However there is difference in perception between my effect and DAF effect I can assure you that - I know what is the difference, however this data won't be released due to my rights as inventor.

When we're using my effect we can hear ourselves in earphones when we're talking to the microphone ( with delay which we can regulate to our own need )

There is one VERY important ( crucial ) rule it must be fulfilled during use of my Invention, stutterer must slow down his speech. So he must hear his voice to go with the same speech tempo with this one he will hear in earphone like in choir speech, not to be ahead of it, but to with it. If he won't slow down his speech in satisfactory level the idea won't work or will work in partially strength only.

I made ( until now ) tests on me, and I made tests on another 5-6 people ( age 25-65 ) in UK including heavy stammerers. And they ( heavy stammerers ) stopped ( from 60 to 99 % of their stutter ) to stammer, theirs blocks were mostly / or in large % reduced.
Next tests were done in Poland. Another over 20 Stutterers took part in those tests and results were mostly full success. 

There isn't my idea to tie you to my effect forever. I hope when using my Invention after time you will be able to forget about App 2beFluent when you will be speaking fluently.
It is possible that over some period of time you will feel more safe when still to have it with you - when switched off but available to use it ( if you feel you need to ). 

The next ( not final ) step of my idea is to make Android App which is in create progress just now. 1st App 2beFluent version should see daylight soon.
The person who stutters will be able to download App from any place on the World when there is Internet available and using own device ( Smartphone, Tablet ) based on Android would be able to use it outside.

I'm just in progress of thinking how to organize distribution and way to pass you my know-how, it's very possible ( tbf certain ) that I'd need to set up " lessons " - probably on-line. Without my knowledge, experience, how to practice with it, some people may struggle with it, at least at the beginning of to use it.
I feel that my and I hope your happy day to try it will be coming soon.
