What is ModelTalker?

The ModelTalker System is a revolutionary speech synthesis software package developed by the Nemours Speech Research Laboratory and designed to benefit people who are losing or who have already lost their ability to speak. It allows people who use a Speech Generating Device (SGD) to communicate with a unique personal synthetic voice that is representative of their own voice.

4/6/2017 – Voice Auditioning

We are introducing a new feature that will allow users to have more say in the process of constructing their synthetic voice. In our lab, we create multiple versions of each user’s voice and then test them to see which one seems best. Our final choice becomes the voice we return to the user. We have now set up a process where users can audition the multiple versions of their voice and help us decide which version sounds best to them. See Voices > Auditioning for more information.

1/19/2017 – Automating Custom Inventories!

Users often ask if they can send us some names and/or phrases to record as part of the voice banking process. It is now possible to create your own custom inventory to record along with our standard inventories for voice banking. At any time while recording your full voice banking inventory, you can select Session > Custom Inventory. This will allow you to enter some names and phrases that you especially want your voice to be able to pronounce correctly. Custom sentences generated from the words and phrases you enter will automatically be added to the end of your active inventory, ready for you to record before we build your voice.

11/26/2016 – New feature for assistance with voice banking

Many people using our site for voice banking are working with the assistance of a clinical specialist (speech/language therapist or pathologist) or a friend or relative. We now provide a CC email address on the registration form for people doing voice banking to designate someone who should receive copies of emails we send related to the audio screening process and voice completion process. Be sure to ask your clinician or other assistant if they want to be copied before entering their email address.

6/21/2016 – New registration features

We have shifted to a new, more secure, password scheme. If you lose track of your password, it will no longer be possible for ModelTalker staff to send you the password. However, if you have forgotten your password, you can now reset it via a “Forgot password?” link on the login page. Along with this change, we have added an Account page to the Registration Menu that will allow you to change your password when you are logged in. Soon we will add some more features to the Account page to let you update email address and other information.

5/10/2016 – New Microphone Setting

We have introduced a new feature in the online voice recorder settings that shows which microphone our recorder is using. Always connect your microphone before starting Chrome, and always make sure that your USB microphone is the one showing in the settings dialog box. There is some additional help you can access from the Settings dialog if you have trouble.

1/21/2016 – Support ModelTalker

Our primary research efforts are directed to creating natural personalized voices for children who are dysarthric and unable to do standard voice banking. Your donation to ModelTalker through the Nemours Fund for Children’s Health supports that research, but it also helps us to continue to provide personalized voices to patients of all ages who have ALS/MND or another disease that can lead to loss of speech. If you or someone you know has benefited from our voice banking service, please show your support with a donation using the Contribute button on this page!

12/28/2015 – New Navigation and Registration options

The menus have changed on our website to improve navigation and make it easier for you to find what you need! We have also revamped our registration process. There are now three options for registering: Voice banking – the option for anyone who needs a personal synthetic voice for use with a Speech Generating Device or App; Voice donating – the option for people who want to donate a voice for others; Assisting – the option for clinicians and others who are assisting someone with voice banking. Unfortunately, we are no longer able to create free synthetic voices for any other reason.

12/21/2015 – New Features in the Web Recorder!

We have added a new feature to the web recorder that will make it much easier for users to review previous recordings and redo ones that had problems. In the Listen menu, choose recordings and you will see a list of all the recordings you have finished so far. Click on a sentence in the list and click the Listen button to review your recording of that sentence. Now you can also click the Record button to rerecord the sentence if you want to.

To further assist with navigating through the list of sentences as it grows long, the sentence number of each sentence is also displayed in the upper left corner of the center text display.

Important information on Logitech G430 microphones

We have recently encountered a number of users with Logitech G430 headsets who are experiencing problems with unacceptable microphone audio. This is a problem we have now also replicated in the laboratory on Mac computers, with the microphone input varying suddenly in amplitude. Our recommendation is presently to avoid purchase/use of the Logitech G430 for Mac users. We are not sure if this may also be a problem for Windows users, but it may be best to avoid that microphone headset entirely.

New Study on Speech Technology for Children with Cerebral Palsy

We are launching a new study as part of our Clinical Speech Technology Program! The goal of the study is to provide personalized synthetic voices to children with cerebral palsy and demonstrate the benefits to these children of having a voice of their own. For more information and details on participant recruitment, click here.

We are also actively seeking voice donors to build a synthetic voice with us that we can then personalize for a child with cerebral palsy to use in his/her SGD. If you live in the Delaware/Maryland/Pennsylvania area and have a child between the ages of 9-15 who would like to donate his/her voice, please email us for more information.

ModelTalker comes to the iPad

The UK-based company Therapy Box is working with us to bring this new technology to the forefront! Implementing ModelTalker voices into usable solutions is a brand new and unexplored field that has wider implications than someone just being able to use an app to communicate. Predictable 4 and ChatAble 2 will be the first iOS apps to utilize ModelTalker voices for AAC, greatly influencing the lives of those with communication difficulties.

You can now choose to download your ModelTalker voice for Apple computers running OS X 10.5 or newer. Your voice will be installed as a system voice that you can select from the System Preferences Dictation & Speech control panel.

Support for Android devices

ModelTalker voices are now compatible with the Android Speech TTS API. Your voice can be installed as the system default voice, and/or used by many Android Text to Speech applications.
