Summary of Key Points for a Successful Trial Period



Minimum computer requirements: 

Laptop PC computer or media tablet with i5 or better processing speed and at least 4GB memory at a minimum is necessary to run the Interact-AS software.  Using a computer that does not have sufficient processing speed or memory is not compatible with the Interact-AS software.  The software is not designed for use on Macintosh computers, however some users have had success with Bootcamp to allow use of the software (not supported for troubleshooting).Refer to the Computer Set-Up for more information.

Plugging in the microphone: 

If the laptop/media tablet does not have separate headphone and microphone inputs you will need a USB Digitizer cable.Many economy-priced computers have only a single microphone/headset input and will not allow the teacher’s speech signal to be translated by the Interact-AS software. An inexpensive alternative to finding a computer with dual inputs is to use a cable that allows the wired headset microphone and/or the FM receiver to be plugged into the USB port of the computer.

Ready to gather data 1:1 (not classroom): 

Work 1:1 to allow the student to practice using the speech-to-text translation and allow you to gather listening comprehension data with and without use of the speech-to-text translation. Refer to Ideas for Assessing Benefit.

Laptop/media device needs to ‘hear’ the classroom teacher: 

If you are doing the trial period in the classroom and introducing the teacher’s voice through the FM teacher transmitter with a boom microphone then an FM receiver must plug into computer so it will transmit the teacher’s speech to the computer/media tablet for translation. See Computer Set-Up for various options for using FM plus Interact-AS.

Microphone specifics: 

$99 Interact trial componentsIt is strongly recommended that the $99 Interact-AS Software + High Performance Microphone System Trial Program (see photo) be utilized to maximize the likelihood of an issue-free and optimal trial period. The Microphone System has been specifically designed for speech-to-text accuracy whereas FM systems have not.

Although it will result in lesser accuracy, the student’s FM system may also be used with Interact-AS. The Phonak MyLink+ or Oticon Amigo Arc have the ability to plug into a computer via Pure Audio USB Adaptor Cable, which is necessary for the laptop to ‘hear’ the teacher. Students who already use an FM system need not change their receiver. The teacher’s FM transmitter must use a boom microphone for translation accuracy. If a boom/collar mic is not used by the teacher then the translation accuracy will be poor. Regardless of the type of FM system, the accuracy of speech-to-text captioning will be poorer than if the recommended High Performance Classroom Microphone was used. See Computer Set-Up for more information on the various options for using FM plus Interact-AS.

Training the software for optimal translation accuracy: Each user (teacher) will need to have an account set up. They will need to read a few paragraphs so the software can set up a translation profile for the best accuracy. The process will take less about 5 minutes – even students can become responsible for setting up new teacher accounts! Improved accuracy can occur if the teacher trains the software, exits the program and goes through the training process a second time. At the end of each period, the student can save the program so it continues to ‘learn’ the teacher’s individual speaking characteristics (translation accuracy can improve over time to 90%-95% or greater accuracy, especially if teacher tips below are followed).


1. REPEAT STUDENT POINTS! The Interact-AS will only translate what is said directly into the teacher’s microphone. A teacher MUST reiterate or summarize student comments for this information to reach the student using an FM/Interact-AS.

2. PAUSE! Interact-AS analyzes speech occurring between pauses as part of the algorithm that results in high accuracy. Most teachers already pause frequently to enhance the student’s ability to process the information so this issue does not arise very often.  Teachers who speak very quickly, without pause will generate text translations that are delayed in appearing on screen.

3. ENUNCIATE! Individuals who do not clearly pronounce words will generate speech-to-text translations that have less accuracy than for teachers who have typical enunciation of speech.
