Top Voice API Use Cases & Steps to choose the Right Voice API

Voice API is an application programming interface acting as connective software used by companies to make calls and receive calls into their application or software or network. Communication API such as voice API can be used in a large number of applications like virtual call centers for outstanding business benefits.

Defining Voice API

Simply defined, voice call API are core components that developers use for seamlessly building call logic and functionalities into other applications. Essentially, voice API integration allows developers to connect their apps to the public switched Telephone Network (PSTN). The evolution of communications has led to voice API integration that delivers specific functionalities for certain uses. Some examples of voice API for developers use are – IVR, call tracking, click-to-call capabilities, virtual ordering instructions, and other applications.

Let’s Consider Some Examples of Voice Call API Use Cases

1. Voice Instruction – A voice instruction feature, using voice call SDK helps in improving the user experience especially in e-commerce apps and food delivery apps. For example in a food delivery app, the voice instruction feature allows the buyer to customize the food preparation in real-time using voice chat SDK.

2. Voice Reminders – This is an essential feature that banking apps and financial services apps are leveraging to notify clients, typically using the voice chat app. Companies that are involved in credit card services and financial lending services with integrated WebRTC voice API will send voice reminders for payments on time, in addition to SMS or text messages. Ideally, pre-recorded voice reminders can be incorporated by the developers for customized reminder voice calls.

3. Voice Support – A very useful feature to add in consumer support with the WebRTC voice call being able to provide instant voice solutions to client queries and requests. Using analytical data we can provide all-important, call recording for an interactive voice response, session initiation protocol, and call logging within the calling sequences processes. Developers can advance the features that their app offers by including Data Analytics within the business applications to develop voice chat apps.

4. Call Authentication – Most applications need One Time Password (OTP) validation of the user, and text-OTP is insecure because of SIM swap fraud. Along with text-OTP verification, face recognition and finger touch sensors can be configured for authentication with Voice OTP calls. Voice API for developers helps in developing call authentication features to deliver web voice calling features.

5. Video Conferencing – This is one of the most popular use-cases during the Covid pandemic. Using Voice APIs leading providers like Twilio, Contus Mirrorfly Voice APIs are offering dedicated video conferencing solutions. These solutions allow developers to leverage conversation APIs using IP Messaging, SMS, PSTN Voice, WebRTC voice API.

6. Telemedicine Features – Developers can integrate messaging API as well as voice call API to provide an ecosystem that supports telemedicine solutions. It can also include virtual calls and real-time chat within your app for users and health providers.

7. Virtual Call centers – is software that is a cloud-based solution for inbound and outbound calling in a virtual environment, using Voice call API. Using web RTC, WebRTC API-based features for creating calling sessions on the browser via API protocols such as RTC Peer connection API of web RTC, these solutions are developed. It helps in the reduction of the infrastructure for an auto call distributor where physical calls are handled over devices ensuring cutting-edge quality call deliveries.

What to look for when choosing the Right Voice API?

Given the broad range of top voice call API currently available in the market currently, it is tough to choose the solution that will match your use case technically and customization. Therefore, two things – the API and the API provider – are critical factors to consider when short-listing the white product you will use.

How do you identify a good Voice API?

The core feature is the usability factor of the WebRTC voice API. If the API is complex and not simple enough to use, does not have needed developer documentation for you to adapt to your project, the time taken to develop and the cost of the project will also shoot up.

To choose the best voice API the following six core factors have to be met:

1. Developer experience (DX) has to be high

The features should be agile and flexible enough for you to include in your project, without needing much help from the API provider. However, whenever you have a development snag in using the web voice calling API, the support delivered will be critical to the overall developer experience.

2. Development tools are included

The purpose of a WebRTC API is that it includes pre-coded software for developers to include in their main project and not lose time and resources to develop voice calling functionalities. If the API provider has efficient and problem-solving developer tools including in their boutique of tools, such a voice API for developers is a good choice to use.

3. Developer documentation and SDK is top quality

For a developer, the language in which the API is developed is not the key, but the documentation for the Software Development Kits, for needed information, is critical. Where these are absent, it will cost you as a developer in terms of money and time for resolution of issues and bugs.

A Voice API provider should have following specific features

4. Licensed API developer is important – Since a licensed carrier is the one to connect to its own network, there is greater control on the service that your API will deliver. You will be able to leverage the phone number inventory of the API provider.

5. Network is all important – Voice calls can be effective only if there are no latency issues to overcome jitter, lag and packet loss so that there is no voice data vulnerability leading to cyber attacks. Using third-party networks is more recommended than open internet but API developers cannot fix connection issues with third-party networks. Hence, the recommendation is to opt for an API provider’s own network and third-party operations.

6. Round-the-clock support – Voice API issues need to be resolved at any time they arise, hence API providers should be continuously offering support to keep the application running consistently.

Conclusion:

Hence, the key factor of a voice API is the agility and the flexibility it brings to the business. Frankly, there is no other alternative that is as powerful as Voice API which delivers the same level of voice connectivity into an app/technology stack. Only, the right voice API will ensure that your business processes get the needed agility and power.
