Media Streams is a new feature introduced by Twilio that allows businesses to access the raw audio stream of their phone calls in real-time, enabling them to improve customer experience through sentiment analysis or AI-driven knowledge assistants. By leveraging this feature, businesses can resolve difficult customer conversations, increase productivity of call center agents, reduce fraud and speed up authentication, among other benefits. Media Streams works by forking the media of a phone call in real-time, allowing businesses to integrate with their own applications or utilize third-party services. The feature is available through partnerships with Google Cloud, Gridspace, and Amazon Web Services, providing developers with access to advanced capabilities and technologies like AI and machine learning. Businesses can get started with Media Streams by using the Stream instruction within TwiML or by integrating with Gridspace Connector, and pricing starts at $0.004 per minute.
