Twilio Changelog

The new Media Streams API gives you access to the raw audio stream of your Programmable Voice calls by forking the audio stream in real-time and sending it to a destination of your choosing using websockets. Media Streams can be used for use cases such as real-time transcriptions, sentiment analysis, voice authentication, and more by sending the forked audio stream to your own application or a third-party service such as Google Cloud Speech-to-Text, Amazon Lex, or Gridspace Sift.

Our real-time Email Validation API helps protect your sending reputation by validating email addresses before you send to them. Use detailed results from our machine learning-powered, mailbox provider-friendly API to alert subscribers of possible typos while they’re still in the signup form and protect your sending reputation by decreasing the risk of your email bouncing. Currently available for free to Pro and Premier Email API plans while in Beta. Learn more about this announcement, how to use it, and the future pricing.

Our new serverless REST API makes it easy to deploy code to Twilio Functions, our serverless code execution environment, and Twilio Assets, our static file hosting service. This new API allows code written in NodeJS and static asset files to be created locally and deployed to the Twilio Serverless environment. The REST API can be used directly with the Twilio helper libraries, or via the Twilio CLI and the Twilio Serverless Toolkit.

Existing Functions and Assets are incompatible with the new API, but they will remain accessible via the web Console as they are today.

To find out more and get started with the new API, visit the new Runtime section of the Twilio docs.

The Flex Plugin Builder v3 is now in Beta. This release enables you to build and deploy your plugins directly from the CLI by leveraging the Functions & Assets API. You can integrate the release of your hosted Flex plugins within a CI/CD pipeline.

To opt into the newest version, check our upgrade guide for using the Plugin Builder.

To help you manage two-way communication with your customers, today we released a new API called Twilio Conversations. Using Conversations, it's easy and quick to build cross-channel messaging applications: SMS to WhatsApp, SMS to Chat, or any other combination. Twilio even exchanges Media for you automatically — no need for webhooks!

Conversations is open to anyone with a Twilio Account. Head over to the documentation to learn more and give it a try.

The Twilio Command Line Interface (CLI) is a new open-source tool to unleash all the power of Twilio from the command line. All of Twilio's REST APIs are supported. The CLI makes it easy to do common tasks like purchase and manage phone numbers, view your SMS and call logs, view Debugger logs, and much more. Visit the docs here to get started.

Autopilot is now Generally Available. Autopilot lets you build, train and deploy AI-powered bots on any communications channel that can interface seamlessly with contact center platforms like Twilio Flex.

The following features are now available in the GA release: pre-built bot templates, speech recognition optimization, new training interface in Console, event webhooks, Simulator to test and troubleshoot your bots, and Custom Channel to let you build bots on custom-built or 3rd-party chat platforms. Learn more here.

The Dominant Speaker Detection API sends events to your application every time the dominant speaker changes. You can use those events to improve the end user's experience by, for example, highlighting which participant is talking.

The Dominant Speaker Detection API is only available for Group Rooms. To enable dominant speaker detection, set the ConnectOptions.dominantSpeakerEnabled property to true. Use Room.getDominantSpeaker() to determine the current dominant speaker. Implement Room.Listener.onDominantSpeakerChanged() method to receive callbacks when the dominant speaker changes.

For more information, refer to the API docs and to the dominant speaker tutorial
