2. Discord “A Gaming App with Built-In Voice”

Discord is a gaming app with VoIP, instant messaging, and digital distribution launched in 2015 by game development studio Hammer & Chisel for dedicated gamers. With discord, it has been appreciated and accepted by the gamers at the very early stage. This has happened since most video games struggled previously with built-in group voice communication in chat apps.

Discord has not only made its presence among the gamers but has also grabbed the attention of the general audience with most of the positive feedback for outstanding functionalities that includes creating servers and channels for a variety of purposes.

It can also be used as a background voice connection during online matches, etc.

3. Telegram “Another Layer of Communication”

Telegram is the voice messaging app that has touched the communication industry, being launched in 2013 by brothers Nikolai and Pavel Durov, the founders of Russian VK. This app has started its presence with amazing functionalities of voice messaging alone, but in the later run in December 2020, it has introduced its worth in group voice chat too. Here, any group chat can become a voice room that also includes text chat and regular media file sharing.

While using a Telegram voice messaging app, you don’t have to stay around all the time, instead can check other chats and send messages. Further adding for Android users, you can also move your voice chat to any floating widget with ease as per your comfort. Telegram does not restrict the limit on the number of voice chat users, instead it creates a barrier on the role of “listener” and “speaker,” with no option of recording and saving of data.

4. TeamSpeak “Bring Users Together on Chat Channel”

Teamspeak (TS) is a VoIP communication app that was founded in 2001. It is one of the best choices for online gaming. Teamspeak uses the most high-quality sound for group calling and is available with a high-end security with almost very minimal performance issues.

Nowadays, voice chat service has become one among the essential needs of people mainly for their robust features and functionalities. Here, we are going to have a look at some of the most essential functionalities that any audio calling app must have, to become an appealing communication source for their audiences.

7 Key Steps Before Build a Voice Chat App

add voice chat to your website

Let’s talk about some of these features and functionalities based on Discord,

1. Multiple channels and Servers

Servers and channels play their role when it comes to building communities. This is so as it is not possible to have a separate space for every individual with regards to topics, projects, etc., to have a discussion.

Therefore, Discord allows their users to have a limited creation of a number of channels that are something like subgroups for servers and participants. Wherein, you can go ahead and have your chat in your community if needed, when the server does not address your needs. Once, you have created the same, the admin will be accessed to,

  • Can create voice and text channels
  • Instruct the users about their role
  • Invite friend and others to join the server
  • Can perform changes with the verification settings to avoid duplicate account creation
  • Transfer all the authority to another account

2. Managing the Roles and Permissions

As have already been discussed, the admins have complete control over the roles and permissions. They can assign a variety of roles to the server and channel members by making changes in every channel’s settings.

Discord allows their users with some basic permission wherein they can have personalized experience with their servers and channels with more than 30 permission options that they can combine and make use of at their comfort. This is one of the major flexibility that Discord provides with management. These basic permissions involves,

  • General permissions
  • Text permissions
  • Voice permissions

3. Chats for Better Connection

Although Discord mainly focuses on voice communication it does provide access to text messaging, as one of the basic app’s functionality. Here, you can make your interaction more valid and accountable with the usage of both voice and chat facility.

Since, Discord is built with an open-source project with WebRTC, you can experience the high-end quality in your voice and video. Moreover, it also opens up the path to file sharing that includes documents, images, emojis, etc.

4. Message History for Better Business Communication

Most of the apps provide the text and voice chat option but will automatically delete the old message once it reaches a certain limit. But, this is not the case with Discord’s message history.

It provides a special space that allows these personal as well as business conversations to be stored on cloud/premises from where the data can be retrieved at the user’s comfort. Thus, Discord makes these old messages to be a source of valuable information, and analyzing them in need by bringing more understanding into any business communication.

5. Screen Sharing Gets Better Interaction

Enabling the way to have more interactive communication is what this screen sharing feature does in Discord. While gaming or watching movies, this feature add-up more fun to the environment. But, when it comes to business it supports voice chat communication with more screen sharing including document, images, etc., in a single call.

Moreover, this feature offers the capability to make notes on the share screen when shared with other participants. This will be very useful if you are planning to create a niche app for any editing purpose.

For instance, here the other participants can make corrections on the screen by offering their ideas which will make the communication more efficient avoiding the need of multiple editorial calls

6. Notifications with Alerts

These notifications with alters connect the users regularly making them to think over their next prioritized task. Mostly, they convey the users about the upcoming events, reviews, meetings, etc., instantly and retain the connectivity.

Moreover, these notifications and alerts enable many more extra features that includes,

  • Mute all notifications
  • Mute notifications for a specific chat or channel
  • Mute the notification for some time
  • Notify the users that you want them to be notified, and much more.

7. Embedding Social Media

As Discord consists of public servers they can be accessed by anyone, sometimes people may try to get connected outside the app too which might require another level of authentication. That’s the reason why Discord has provided this feature of social media integration.

Most of the chat apps provide access to get connected through two to four social media options, it’s the Discord that provides more than anyone else. Let’s have a look at some,

  • Facebook
  • Twitter
  • Spotify
  • Steam
  • Reddit
  • Xbox Live
  • GitHub
  • Twitch
  • YouTube
  • Battle.net

However, the above features and functionalities are as per Discord, but they do differ for the rest of the apps too. But, almost all the apps will have these features with some ups and downs in functionalities.

Now, let’s move on to the main desired section as the key steps to be followed while building a voice chat app.

Once you are done with the market research, it’s time to look for the perfect tech team to work with. If you already have a team of skilled developers then it’s fine, else instead of opting developers as full-time employees, it’s always better and most cost effective to go on with hiring them for your project.

3. Create a MVP “Main Decision Making Point with Investment

MVP or The Minimum Viable Product talks about the most essential part of the entire process. It is there to make you understand the core to hit your target audience. MVP is all about actual products with the most viable and valid functions that allows you to decide whether to continue investing in product development or not, based on many criteria including market’s reaction.

This is to have a clear vision of the outcome as depending upon the users feedback, the further enhancement of the project will happen. Once done with this there comes the market launch to explore, connect, and generate revenue.

Well, these are the most important steps that must be taken into consideration for sure. But, the development is all about the back end process. Yes! The real time tech stacks that work smartly to grab the market.

Tech Stack, the Core Behind Every Successful Voice Chat App!

It’s the technology or the tech stack, the main reason behind the success of any voice chat app.

Yes! They are the backbone of any project that decides the way to build these voice chat apps despite the project’s complexities concerning features and functionalities.

Let’s have a look at the technical stacks that are used to build a real time voice chat app.

After all this great research in all possible terms, let’s move forward with the main section, and talk about the core differences between – building a voice chat app with APIs is better or starting from scratch would be the great choice.

Build Voice Chat App, What’s Best Choice :
Scratch vs. Readymade

Whatever be the case, when it comes to “build your voice chat app,” it’s the core responsibility of a developer to look out for all possible ways.

Therefore, before making a choice to build a voice chat app using APIs or starting something from scratch – I think it will be a better approach if we look on and compare some of the major key notes to have a better understanding to proceed further.

1. Time Frame

It’s always a big deal to finalize the cost and timeframe to build any voice chat app. This is because the length of the time differs depending upon a variety of factors.

Mostly, if you have to go for something from scratch, you have to consider so many factors like,

  • Need to hire an appropriate team of developers
  • Look out for the infrastructure cost
  • Work on each and every coding to build the better backend

However, they seem to be simple but will consume a lot of time that will have a great impact of increase in cost as well as with time consumption.

But, if you opt for a ready-made voice chat APIs to build your app, then you don’t require anything other than your in-house team. This is so as if you don’t have your in-house team then you can proceed with the further integration process using the provided UI Kits itself.

This ready-made APIs integration process will not take months but simple countable days. Moreover, these voice API providers do provide complete developers support till deployment. So, you can be stress free.

2. Pricing – Readymade (SaaS Platform)

We all know that when you are planning to build your voice chat app, the pricing is something that talks about every aspect of the development. The scenario differs for both ,

Exactly! If you are planning to build something from scratch, you have to prepare an estimation depending upon certain things like,

  • Look out for better infrastructure
  • Spending on resources
  • Hiring skilled developers, etc.

However, it’s a known fact that the overall cost at the end will of course be more than expected.

But, this is not the case with ready-made APIs when planning to build a voice chat app.

Well, before getting into the details let me tell you that these voice chat API and SDK providers offer their solution in two possible ways – One time license cost and monthly subscription plan. Let’s have a look in detail,

  1. One Time License Cost – This is the pricing scenario that is based on SaaP model wherein, you have to make a one time payment to have all your desired features for lifetime. Moreover, you can add up your required features too with custom feature options whenever needed as per your business requirement. This SaaP model allows you to have complete ownership of your app.
  2. Monthly Subscription – This pricing scenario is based on the SaaS model that supports the “pay-as-you-go” concept wherein, you can use your desired APIs for a month and pay as a monthly subscription amount. But, in this case you will not have any control over your app, it’s the API and SDK providers who own the admin power. Thus, in case of any issues you have to approach them directly via their customer service support team.

Now, after a deep understanding on the core differences about building from scratch or using APIs, what’s the best.

Let’s have some insight on how these voice chat apps have influenced a variety of industries.

Impact of Voice Chat Apps on a Variety of Industries

When it comes to industries, these chat, video and voice chat apps have made a substantial impact on almost all the industries, from healthcare to online education, or can say, none of them have been left apart globally.

These real time voice chat apps for enterprises have always proven to be a supportive hand when it comes to serving the business by contributing to its success. Let’s have a look at some of the industries.

1. Healthcare Industry

These real time messaging, video and voice chat app services have made communication possible and easy by ensuring HIPAA compliance.

2. Online Food Ordering and Delivery Industry

Online food ordering industry falls under the category of on-demand industry. Today, this industry is booming to the core with its non-stoppable service because of these voice chat apps. This industry is utilizing these real time communication apps as a default supportive system to connect to their customers every single day.

Here, these voice chat apps play their role until the customers receive their ordered item. Moreover, it helps their customers to have a track of their ordered food with exact location tracking until they receive them.

3. E-commerce Industry

Unlike the food industry, even e-commerce or online shopping falls under the on-demand category. This is mainly because nowadays, people feel more comfortable shopping online instead of visiting the shops directly.

These real time voice chat apps are the real time chat for retailer brand engagement wherein, they have cleared the way by connecting the retailers and the customer on the same page. Moreover, these audio calling apps have also made a secure pathway for shipping and payment ensuring end-to-end encryption by tracking the items.

Coming to the end of the section, I hope that now you would have obtained a clear vision as to why it is important to create your voice chat app.

Now, it’s up to you to decide depending upon the above mentioned key factors whether you want to go on with building something from scratch or using the real time voice chat APIs.
