Last update: 2020-08-28

Mix 3.4.0 — 21 August 2020

Feature highlights

The main features of this release are summarized below.

Mix.dashboard

A new tab, called Manage, is now available in Mix.dashboard. This tab lets you perform all the tasks related to application management such as creating builds, creating and deploying application configurations, and managing namespaces. The Manage tab replaces the Applications and Namespaces tabs. For more details about this feature, see the 2020-08-21 Change log.

You can create, and delete, multiple client IDs for the same app ID. See Create a client ID for details.

Mix.nlu

Mix.nlu now includes a verification workflow for project samples, giving you more control over which samples are used for your models. Samples automatically transition from the Intent verified to the Fully verified state when an annotation is added. This signals to Mix.nlu that you intend to add the sample to your model. You can always choose to assign a different state to the sample; for example, to exclude it (change the state to Excluded) or to use it to detect intent only (change to Intent verified). For more information, see Verify samples.

Note: Further enhancements are coming soon, including clearer verification state names, enhanced state indicators and easier state transitions, verification state memory for excluded samples, and verification state filtering.

Mix.dialog

Enhanced settings allow dialog designers to better control and augment the user experience. Use the new global confirmation settings to determine whether the app should prompt the user for confirmation when a recognized entity returns with a confidence score that is between the low and high confidence thresholds specified in the collection settings. You can reference the entity in focus during confirmation by inserting the dynamic Current Entity value placeholder in global confirmation messages. Predefined and custom entities now also have their own set of settings under each channel profile, so that the collection and confirmation behavior can further be tuned and tailored to the information being collected. Furthermore, it is now possible to override settings at the node level, in the Advanced tab of question and answer nodes, to further tune these settings locally and provide dialog designers as much control over the user experience as possible.

Note: With the current version of Mix.dialog, settings apply to all languages in multilingual projects.

Other new features and changes

This release introduces the following additional features and changes.

Languages and voices

New languages: English (India), Hindi (India), Italian (Italy), Portuguese (Portugal), Russia (Russia), and Spain (Spain). For the complete list, see Languages.

New voices: Hindi, Tamil, Telugu, Chilean Spanish, Columbian Spanish, Russian, Malaysian, and Vietnamese. For the complete list, see Text-to-Speech voices.

Mix.nlu

Support for locale-specific literal-value pairs in projects with more than one language/locale. For multilingual projects (projects with more than one language/locale), literal and value pairs are now locale specific. This means that if you add a value to a list-based entity, the data will be specific to the locale where this operation was performed. Similarly, if you delete a value this change will impact only the locale where the deletion was performed.

Mix.dialog

Deprecations and removals

TTS as a Service: The v1beta1 protocol is obsolete and no longer supported.

TTS voices: The following language variants will be removed in an upcoming release, as noted in Text-to-Speech voices.

Nuance Mix now supports building a customer experience in multiple languages all within one Mix Project. At project creation, you can select which languages are supported and then activate/deactivate languages as needed as well as customize the experience inclusive of prompting and logic on a per-language basis. Finally, Mix.nlu supports adapting a centralized ontology with training data, annotations, and entity customizations on a per-language basis for optimized performance. For more specific details, see the 2020-06-11 Change log.
