Once a struggle, now after some updates it is amazing…

As I was tapping out a reply to the chat help person, I received my first Olelo call and the captioning and speed was ah-may-zing. Perfect. Both speed and accuracy. I even asked the caller if he could give me his impression of the delay in conversation while the speech-to-text was occurring and he said “there wasn’t any delay, I wouldn’t have even known…” That, is incredible. I’m late deafened (profoundly) and was a SpEd Technologist responsible for Accommodations and Adaptations for students and have looked at and used so many options as I am not proficient at ASL. Hamilton, InnoCaption, Ava, none of these were even close to the accuracy and speed of my first Olelo use. It was a pleasure talking on that call. Like I am still smiling. Thank you so much. Once the personalized voicemail greeting issue is figured out this app will blow away the other options.

Good App - Needs One Thing

This is a great caption app I always love the captioning of both ends for historical purposes and recall. Very handy. I didn’t find any way to quickly adjust the tone of the speakers voice from within the app. My hearing impairment make it difficult to hear deeper male voices. So some method of tone manipulation to increase the clarity for those that need it or either end of the spectrum of sound and impairment. That is the one thing I can think of at this first testing that would be a great improvement. Might I suggest something easy like Tone: High, Mid, Low to start. Then as development progresses you could add in the settings a way to input your own audio gram to that the tone is lost customized. But start with the easy and work out the other later. I’ve used every method of captioning and apps. I’m always willing to help in development and testing of possible betas for your profound hearing impaired users as someone with an IT background and Great understanding of the current technologies available for the hearing impaired and captioning. Much appreciated feel free to reach me. - David /. If I missed the current way to do the tone manipulation, just let me know. Thanks.

Very happy camper!

I used other closed captioning apps for my iPhone and found them completely unreliable and unusable. I almost gave up until I found Olelo. I was extremely surprised and happy to discover the effectiveness, timeliness, and reliability of Olelo captioning. Before, I used to let calls rollover to voicemail in hopes I could figure out the message after repeated playbacks…but not any more! Because of Olelo, I now answer my live phone calls with far more confidence and found greater success in engaging with callers. Thank you Olelo! I can now call the world!
