Fantastic App!

Speech Assistant is so easy to use and customize. Love that there are diff voices and with the ability to change voice pitch and speech rate. It’s very intuitive and my 85-year old patient, who hates “technology,” was able to use it easily after a 5-min demo! Thank you to the developer for this clean, functional, flexible, and intuitive program...and it is extremely affordable. I’m so grateful to be able to recommend such a fine App to my patients!

Wonderful App

I use this for an aphasic client. Extremely easy to program with novel “carrier” phrase/question-forms for repetitive practice. I wonder if there is a way (I may have missed) to make the pictures I’ve programmed onto the text buttons appear in the larger read-out text windows. That would make the stimulus selections more salient and appealing. Otherwise, the application is terrific, very reasonably priced, and always useful.

Great app for speech

I love this app. It has really helped me communicate with everyone. I am very happy that it has a way to make the text larger as I am visually impaired. The one thing I would really like if it was added was if each of the buttons could be customized with a color so I could find the button I want faster. Overall Great app!

Developer Response ,
