Best Voice Authentication API For Developers

If you are a developer, you must have heard of voice authentication and its benefits. With the use of this technology, you can verify the identity of your user without having to necessarily ask for additional information. This is very useful if you are working with a limited number of devices, or simply want to provide your customers with a simpler authentication process. In any case, this is not something that you can do by yourself. First, you will need to implement it in your app, and then you will have to think about how to make it work. Luckily for you, we have prepared an article that will guide you through everything that is necessary for the recognition of a person’s voice. 

How does it work?

Basically, voice biometrics work by storing your acoustic features in a database and comparing them with those of other users to verify the identity. These features are usually captured in a sample, which is stored in the system for future comparisons. These may be a personal identifier such as a name or date of birth; or an access credential like a password or PIN. 
However, most voice biometrics use voiceprint as the personal identifier, which is a digital representation of an individual’s unique vocal characteristics. In addition, these allow companies to verify the identity of their users using only their voice, without having to enter other information such as passwords or Pin codes. 
When a person speaks into a microphone, several characteristics are captured: pitch, timbre, amplitude; and they also depend on environmental factors such as background noise and impediments like nasal congestion or mouth full of food. 
These are analyzed by an algorithm that computes the acoustic features into a vector with real value. The information contained in it will allow the system to determine if two persons have the same voiceprint vector. 

Who can use it?

From now on, not only developers can use it in their application development process. Any company is allowed to test this API to develop its own verification tool.  It can be used by security companies or private clients that are looking for user validation on their site or application; but also by private persons who want an extra security on their online bank account! 


This particular API allows you to check if two voices are the same by comparing them. It will get two voices and compare them mathematically to determine if they correspond to the same speaker; but it will not decrypt them in any way.
This API will help you to recognize if two audio files’ voices belong to the same person or not. Ideal for security validations.

To make use of it, you must first:
1- Go to Voice Coincidence Verification API and simply click on the button “Subscribe for free” to start using the API.
2- After signing up in Zyla API Hub, you’ll be given your personal API key. Using this one-of-a-kind combination of numbers and letters, you’ll be able to use, connect, and manage APIs!
3- Employ the different API endpoints depending on what you are looking for.
4- Once you meet your needed endpoint, make the API call by pressing the button “run” and see the results on your screen.
