That description is very different from what they were trying a couple of years ago.  That would make it much more like a “switch” as we define it.  But very different from trying to use it to turn into algorithmic speech, which is what they were trying for previously.

 

So actually not much different from something like the Impulse (ablenet) connected to scanning software of their design.

 

Oh dear…

I recently requested a trial of the product.  The representative actually apologized about the product’s misleading advertisement and explained the system in detail to me.  She emphasized this product “does not read your mind” nor does it “make you speak”.   Apparently there have been several calls asking these questions….  HMMM..

 

It is intended for individuals who are “Locked-In”.  The users provide their Credit Card number up front.  Following the 2 week trial of the product, users offer feedback to the manufacturer if not going forward with the purchase or the system is purchased using the credit card number provided.

 

The system includes a sensor (otherwise known as a switch) attached to a “highly shielded cable”, software, and a notebook PC.  The “Highly Shielded Sensor” was emphasized as being so sensitive that is may pick up electrical noise necessitating the “shielding”.   It is a Beta System therefore not Medicare approved.  I was told if our facility tries it for 2 weeks, we can purchase the product for $500.00 as opposed to the listed price of $5,000.   We would need to sign a Beta Contract with the expectation to offer feedback.  Free software updates as released.   

 

There are 2 levels to the system:

 

1)       First phase, the individual using the system is attempting to select scanned programmed phrases highlighted one at a time (I wasn’t able to tell if this was linear scanning or row/column.  Based on the description it sounded like Linear scanning—ouch!).

2)       The next phase the individual learns is how to spell out words and phrases.  It sounded like one page was a split keyboard with the alphabet linked to several pages and if I understood the description correctly, each page included a set of commands (clear, backspace, speak all). 

 

In order for the client to activate the switch, the client must essentially try to speak.  In theory, the individual thinks about speaking sending the signal to the nerve that activates the MUAP.  Again, this is the information I received from someone in sales. 

 

I have so many questions about how this system operates and would prefer to be able to answer questions individuals are asking now so I requested the trial.

 

I was able to see this demonstrated about a year ago.  I’m very concerned that people will get the wrong impression from the marketing material and promotional literature in terms of what really happens.  When I saw it, the system could not “pick up” any word that the person “thinks,” only words that had been preselected or stored for recognition.   When I spoke with the developers I got the impression that they had little background experience regarding AAC, high frequency vocabulary and what that means in terms of generating utterances.   I’m sure more has been learned.   However, a lot of good intentions.   Still I’d like to see the clinical trial data in terms of measures that demonstrate interactive communication, e.g. MLU, % core vocabulary, rate, accuracy, etc.

You’re right – it’s a switch access method at this point.  They are hoping that the sensors will eventually be able to consistently differentiate signal length or intensity in order to identify and “speak” selected words.  That’s where the “converts signals to speech” part comes in. 

 

 

I have a little info to share with regard to Audeo Beta testing.  I had hoped to wait until I could actually get my hands on the system but in the meantime, here’s what I know…

 

The caregiver of one of our nearly locked-in ALS patients recently contacted me about the system then set up a trial with Ambient.  As they live about 3 hours from our center, my involvement thus far has been only via email and phone.  Last week I listened in on a trial facilitated by their home health PT and Kimberly Beals.  From what they are saying, as long as the user has some “intent to speak”, the sensors (which are supposedly far more sensitive than the Impulse sensors) can pick up motor unit action potential (MUAP) in the laryngeal area.  It is still very difficult for me to grasp but the patient who has the unit has apparently had some success.  On command, he tries to talk or thinks about trying to talk and the sensors are able to detect enough MUAP to reach a threshold set within the software and interface with a PC to select a word, phrase or letter.  At this point they’re only working on consistent yes/no selection but the PT thinks it has a lot of potential for this patient and others.  If the trial continues to go well, I hope to see it live in the near future. 

 

Time will tell…

Speech Device Available for Free Trial
It reads muscle impulses to produce speech

by Alyssa Quintero

After rigorous testing and feedback from people with ALS, the Ambient Corp. has released the beta version of its Audeo speech system (pictured), which reads brain signals sent to the vocal cords and uses them to help produce speech.

Designed for people with ALS, the Audeo Beta Package (www.theaudeo.com) relays electrical impulses from the brain to a small laptop that converts the signals to speech. The system doesn’t read minds or give voice to random thoughts, but picks up muscle impulses created by conscious efforts to speak. (“Beta” refers to the fact that the product is still in development.)

Potential buyers must submit an application before a device can be shipped. Then, users can test it for two weeks before purchasing or returning it (no rental fee or deposit is required). Even if people return the device, Ambient relies on their feedback to improve the Audeo system and software.

The Audeo package ($5,000) includes the sensor and neckband, portable laptop with preloaded software and video tutorial. Users receive free hardware and software upgrades as they become available.

“It’s the most natural way that you would talk to somebody,” says Kimberly Beals, communications director for the Ambient Corp., which is based in Urbana, Ill. “You’re using the same movements to talk that you did before ALS. You just have to figure out the best place for the sensor and how to get the best signal.”

To receive an in-depth Audeo guide and application, contact Beals at (217) 408-4085 or by e-mail at xxxxxx@xxxxxxxxxxxx.
