When a landline caption phone might be a better option

InnoCaption's service work on the smartphone, tablet, or computer you already own, but it's not the right fit for everyone. CaptionCall may serve you better in two situations.

Lack of cellular / Wi-Fi coverage

If you don’t have reliable cell service or Wi-Fi at home, a CaptionCall for Home phone could be the right option for you as long as you have an ethernet connection.

Traditional landline phone is necessary

If you prefer a dedicated landline phone with a traditional handset—rather than using your smartphone, tablet, or computer—CaptionCall for Home is a good choice.

InnoCaption users

I love InnoCaption too. I use it for every single call. One time I had to call a tow truck stuck in an unfamiliar city with my stuck car all alone. Thank goodness I had InnoCaption and could make the calls I needed to get help.

I am hard of hearing and am constantly asking what?? On the phone, but no more! With this app I can also type my replies which is amazing because I can easily go nonverbal when talking on the phone due to psychological issues.

Frequently asked questions

Is InnoCaption really free?

Do I need a landline phone to use InnoCaption?

No. You don’t need to purchase or install a new, specialized phone. InnoCaption works seamlessly on most smartphones, tablets, and computers.

Are my calls private?

Yes — your privacy is incredibly important to us. Our privacy and compliance procedures are regulated and audited by the FCC, and we apply HIPAA standards to our security measures.

Here are some of the steps we take to ensure your privacy on calls.

No call audio logged
When you use the automated speech recognition option for captioning, no call audio is logged for machine learning or any other purpose.
One-sided listening
Our stenographers are trained professionals subject to stringent compliance requirements. When you use the stenographer option for captioning, the captioner can only listen to and transcribe the other side of the conversation — they don’t hear what you’re saying. (The only exception is conference calls, when the stenographer hears everyone on the line.)
Private transcripts
Call transcripts are private and cannot be accessed or retrieved by InnoCaption or our staff. Only you can access, save, and restore your call logs since they are stored on your device or backed up to your personal iCloud or Google account when you enable auto backup.

Who is eligible for this service?

InnoCaption is for anyone who has trouble hearing on the phone and needs captions to understand the other party, or has a speech or hearing disability and needs assistance speaking on calls, and is located in the United States.
