RESULTS

  • Improved overall user experience
  • Boosted overall user verifications
  • Decreased developer resources using an API solution

For deaf and hard of hearing people, communicating via 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 recognize the number, they are less likely to answer, thereby disrupting the user experience of the app.

Finding Nexmo

To solve this issue, RogerVoice sought an SMS-based user verification process to authenticate new registrant’s phone numbers, which are then displayed as a CallerID. RogerVoice partnered with Nexmo 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 correctly enters their phone number, 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 Nexmo’s user authentication API allowed us to legitimize the service and our user base. Nexmo’s customer support team have been efficient in helping me get set up, and have resolved any issues quickly. Nexmo’s global scalability is critical as we currently cover international markets,” continued Jeannel.
