Results

Improved overall user experience, boosted overall user verifications and decreased developer resources using an API solution.

For deaf and hearing-impaired people, communicating via a mobile device can be challenging. RogerVoice, the leading telecommunications voice recognition solution for deaf and hard of hearing people, provides users with the ability to start a phone call and receive instant live transcriptions of what the callee is saying.

It works in multiple countries and languages. In addition, the instantaneous speech-to-text and text-to-speech synthesis of phone conversations allows for a seamless communication experience.

“Until the RogerVoice app was created, there was no easy means for the hard-of-hearing to make phone calls. Therefore, it was very important that we create the most seamless user experience possible,” said Olivier Jeannel, Founder of RogerVoice.

Typically, when a user makes a call from a VoIP app, their phone number appears as “unknown.” If the call recipient does not recognise the number, they are less likely to answer, thereby disrupting the user experience of the app.

Finding Vonage

To solve this issue, RogerVoice sought an SMS-based user verification process to authenticate new registrants' phone numbers, which are then displayed as a CallerID. 

RogerVoice partnered with Vonage to use its SMS API to enable two-factor authentication for new app registrants. When a user signs up, they enter their phone number and receive a unique pin code via SMS. Once the user enters their phone number correctly, they are given full access to the RogerVoice app.

This allowed RogerVoice to successfully improve overall user experience, boost overall user verifications and decrease overall developer resources using an API SMS solution.

"Using Vonage's user authentication API allowed us to legitimise the service and our user base. Vonage's customer support team have been efficient in helping me get set up and have resolved any issues quickly. Vonage's global scalability is critical because we currently cover international markets," continued Jeannel.
