Twilio Changelog

Twilio now supports Amazon Polly Neural Text-to-Speech (TTS) Voices allowing you to use higher quality voices with TwiML <Say> in your voice applications. The ground-breaking improvements in speech quality come through a new machine learning approach which converts text into lifelike speech. Amazon Polly Neural voices are currently available in two speaking style voices - Newscaster and Conversational and across four languages - English (British), English (US), Portuguese (European), and Spanish (US).

Try these voices in your IVR applications by selecting them in the TTS console or by setting them in your TwiML <Say> attributes. For more information on the voices and on pricing, please visit Twilio Text-to-Speech docs and Amazon Polly docs.

This release of Flex UI introduces a pilot release of Advanced Team View Filters. This feature allows supervisors to search or filter their agents by name or activity or use custom, programmatically defined, filter criteria like teams or skills.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.17.

This release of Flex UI introduces an Initial Audio Device Check. This feature allows you to perform an audio device availability check when Flex starts up to make sure you are ready to receive voice calls.

Initial Audio Device Check is currently available as a Pilot feature. To enable it, visit the Pre-Release Features Page. You can learn more about this feature within our documentation.

For a full changelog, visit the Flex UI release notes.

Reminder: You can pin to individual versions of the Flex UI or manage your Automatic Updates within the Flex Admin UI.

Programmable Voice, Elastic SIP Trunking, and Programmable SMS can now support compliant healthcare uses cases that contain protected health information (PHI) for organizations that are subject to the Health Insurance Portability and Accountability Act (HIPAA). Twilio will sign Business Associate Addendums (BAA) with covered entities and business associates for HIPAA Eligible Products and Services.

Twilio Functions makes it easy to deploy custom code onto Twilio to support your communications use cases. Today, we're introducing a new Serverless API endpoint that lets you retrieve debug logs for Functions executions. In addition, the Twilio Debugger will now show Warning and Error level log messages added to your Functions code. You can tail logs from deployed Functions locally via the latest version of the Serverless Toolkit.

To learn more about the functionality, visit the Logs page in the Serverless API documentation.

Today we are excited to announce that we are open sourcing three video collaboration applications, one for iOS, one for Android, and a ReactJS one for the Web. These fully featured apps can be deployed to the Twilio cloud in minutes for your own personal, globally scalable, multiplatform video collaboration solution.

Access to the source code will empower developers to tailor the application to their use case and create a truly unique collaboration experience. The code also provides a canonical reference for developers building on the Twilio Programmable Video APIs.

For additional information on getting started see the blog post here and links to the source code repos are below.

We have added new filter dimensions to the Voice Insights Dashboard. The new filters are:

The Client Insights beta ended in August 2019 with the general availability of Voice Insights. We have continued to respond to requests made to the preview API, but we will cease responding to requests to beta API resources on May 1, 2020.

If your application consumes the preview API resources you will need to update your code to use the new endpoints. We have created a migration guide to assist with update your applications: https://www.twilio.com/docs/voice/insights/client-insights-preview-api-shutdown/client-insights-preview-api-migration-guide

For more information about the shutdown of the Client Insights preview API see https://www.twilio.com/docs/voice/insights/client-insights-preview-api-shutdown

Twilio Functions created via the Serverless API can now be integrated with your Studio Flows through the Run Function widget.

Selecting a Function to invoke in the Flow is easy. For Functions created via the Console UI choose the "Default" service, and for Functions created via the Serverless API choose the Service and Environment where they are deployed.

Twilio Programmable Call Recording now supports Single Party Recordings. The new recordingTrack parameter allows developers to select whether the inbound, outbound or both audio tracks of the call should be recorded. The inbound track represents the audio received by Twilio, and outbound track represents the audio that Twilio generates on the call. Prior to this release, all audio was captured regardless if the recording file contained one or two channels.

In addition, recordingStatusCallback will also include a new recordingTrack attribute that indicates which audio was recorded and this information will be displayed in Twilio Console too.

Learn more about this feature and how to configure recordingTrack in our Blog post announcement.
