Voice SDK refers to a collection of software modules that allow developers to integrate and build real-time voice call features into their own apps or platforms. There are many great voice call SDK vendors on the market for your choice, including ZEGOCLOUD voice SDK and Twilio voice SDK.
Most companies opt for voice call SDK from top vendors, avoiding high costs in building real-time voice call features from scratch. The real-time voice SDK that vendors like ZEGOCLOUD offer have encapsulated the whole technology into their cloud-based system and exposed a few simple voice APIs for your development team to integrate and call. Furthermore, companies don’t have to worry about investment in development and maintenance.
The Common Use Cases of Voice SDK
There are various use cases of voice call SDK. The most common ones include:
Social Scenarios
This category is very broad, it refers to internet-based online entertainment and social networking scenarios. One example of this kind would be online stranger social networking. Social platforms set up voice chat rooms of various schemes, and users join rooms according to their own interests.
Gaming Scenarios
Real-time voice has been a must-have for games. Gaming platforms can integrate voice SDK into their game app to bring a better user experience to users. A common practice in the gaming industry is to build social channels for gamers to share their thoughts and experiences through comments or even voice chat rooms.
Education Scenarios
There have been some innovations in online educational apps where there is no video. With the aids of screen sharing, document sharing, and whiteboard, teachers use real-time voice to interact with students.

The Typical Features of Voice Call SDK
One-on-one, Multiple, or Live Streaming Show
Real-time voice SDK allows your users to conduct one-on-one voice calls or many-to-many group voice chats, or even live voice streaming shows. The fundamental feature of a voice call SDK is to allow users to make real-time voice communication with the best voice quality.
High Fidelity Voice Quality
ZEGOCLOUD’s voice SDK supports full-band voice ranging from 8kHz to 48kHz. The bandwidth of voice stream ranges from tens of kbps to more than 100 kbps. The voice quality can replicate the quality in offline situations.
Acoustic Voice Pre-processing
Noise refers to environmental noise that degrades voice quality. Echo refers to the situation where the far end’s voice is picked up and transmitted back to the far end, and the far end user is disturbed by the lagging and repetitive voice. There are some acoustic processing that are carried out before coding, and we call them pre-processing, which includes ANS(Acoustic Noise Suppression), AEC( Acoustic Echo Cancellation), and AGC ( Acoustic Gain Control). They are must-have features for a voice call SDK.
