Documentation updates

2022 July

2022-07-20

Enhancements

In TTSaaS, you can reference audio files in synthesis requests via secure URL as well as URN, using the SSML <audio> element or Nuance control code, audio. In previous versions, audio files were available only via URN. You can also specify alternative text in SSML <audio> elements, which TTS synthesizes if it cannot access the file. See the TTS as a Service change log for details.

The process to import TRSX and ZIP files was improved. When importing a TRSX or a ZIP file, samples will no longer be dropped when a problem is identified. If a valid intent is referenced, the sample is placed in the intent, in intent-assigned state, without annotations. If the intent is invalid, the sample is placed in UNASSIGNED_SAMPLES, without annotations.

Mix.nlu improvements, including:

Fixed issues

Mix.nlu does not support annotating a sample in a character-based language when it contains user-entered spaces.

Inability to add a second annotation in a sample in some cases for character-based languages.

Tokenization issue for the Thai language: The display splits some alphabets into two or more characters.

2022-07-06

Enhancement

The Runtime Event Logs documentation now includes additional details on events generated when a dialog session is terminated.

Documentation updates

2022 June

2022-06-22

Enhancement

For Mix.nlu, updates to Bulk operations under both Develop and Optimize. When the number of samples is large and samples are displayed in pages, you can now select all samples on all pages to apply bulk operations. For detail, see the Mix.nlu change log.

Fixed issue

(Mix.dialog) Any question and answer node named "company" might generate an error at runtime (class java.util.HashMap cannot be cast to class java.lang.String...).

2022-06-15

2022-04-25

Enhancements

To accommodate different types of HTTP authentication, entering an API key when configuring a webhook in now optional. See Add a webhook in Mix.dashboard.

Users can now download failed ASR builds in the Manage tab. A CSV file is downloaded that lists all errors in the failed build (mirroring the process for failed NLU builds). See Create builds.

Note: Versions has been removed from Mix.dashboard. Now the Details tab includes only the Information and Content sections.

Fixed issue

Mix.dashboard: Importing the JSON file for a dialog model into a project does not update the Details tab and the Targets tab to reflect the channels and modalities from the source project.

Documentation update

See the Dialog App Spec change log.

2022-04-20

Enhancement

For Mix.dialog, improved user experience for the question router node:

2022-04-13

Enhancement

For new projects, the dialog service will no longer automatically add spaces in dynamic messages at runtime. This will facilitate use cases such as embedding a URL with dynamic parameters, in a message. (This previously required using an intermediate variable to concatenate the static and dynamic parts of the URL.)

It is possible to migrate existing dialog projects, to take advantage of this change, by exporting the JSON representation of the project, changing a parameter, and importing the JSON file back into the project.

Documentation updates

See the following change logs:

2022-04-07

Enhancements

In Mix.dialog a new node-level setting allows you to mark a question and answer node as sensitive. When applied, this setting ensures that all user input collected at this node will be masked in the event logs from all services, and utterance recordings will be suppressed—regardless of whether the interpretation results include sensitive entities. For more information, see the Mix.dialog change log. Also see the change log for Mix Runtime Event logs.

The Rate limits section now contains details about the ASR runtime and ASR training services.

ASRaaS is now gRPC-Web compliant. Note that gRPC-web support is limited to demo applications. It is not meant for production-level applications.

For more information see the Dialog as a Service change log.

2022-03-16

Documentation updates

See the following change logs for updates:

2022-03-09

Enhancement

To improve dialog event log readability, only the sensitive part of the overall literal will now be redacted if a sensitive entity is recognized, instead of redacting the entire content. For more details, see Dialog values possibly masked.

For more information about log redaction, see Managing sensitive information in an application.

Documentation updates

Enhancement

Mix's password policy has changed. See Update your password.

2021 December

2021-12-08

Feature highlight

Mix offers the ability to lock a project. You might lock a project that includes multiple active users to perform an action that would otherwise disrupt the team (such as importing/exporting content, creating a build, running tests). For more information, see Lock a project.

Enhancement

TTSaaS provides an HTTP API for Synthesizer, which uses a transcoder to the gRPC API. This feature lets you use a REST API to get voices and request synthesis.

Documentation updates

See the following change logs for other updates:

2021-12-01

Enhancement

Mix.dialog now supports reordering parameters in the Send data and Get data sections of data access nodes and external actions nodes, as well as in the Send data section of question and answer nodes.

Fixed issue

(Mix.dialog) Entity-specific settings: Changing the type of an entity after having configured settings for this entity might result in duplicate confidence thresholds or confirmation strategy settings in the internal representation of your dialog project.
Note: When you validate your design, a warning will identify any stray duplicate setting overrides. To remove the duplicate overrides, open the Project Settings panel, navigate to the entity mentioned in the warning message, and use the Reset icon. Refresh the page and repeat until the Reset icon no longer appears. Configure the setting as desired.

Documentation updates

See the Mix.dialog change log.

2021 November

2021-11-24

Documentation updates

See the following change logs for updates:

2021-11-22

Enhancement

To better align our tooling with the various customer integrations we support, Mix has introduced the concept of engine packs. An engine pack is a set of pre-determined ASR, NLU, Dialog, and TTS engine versions that are compatible. If engine packs are enabled for your organization, you'll be able to choose the engine pack version that corresponds to the engines you have installed in your environment, thus ensuring that the resources generated for your project are compatible with the engines and that you have access to the appropriate tooling features.

For more information on engine packs, see the following documentation:

Important notes:

You will be notified via announcements when new engine packs become available.

2021-11-11

Enhancements

Improvements to Mix.nlu’s Auto-intent feature:

See Apply automation for details.

ASRaaS has an updated proto file that includes a new field for wakeup words. See the ASR as a Service gRPC API change log.

Fixed issues

(Mix.dialog) In the Project settings panel, the Collection default messages and Confirmation default messages sections don't have a modality selector, which might prevent you from viewing messages and their modality-specific variations directly in the panel.

(Mix.dialog) Project settings: Entity-specific settings are not available for custom entities that have an isA relationship to another custom entity.

Documentation updates

See the following change logs for other updates:

2021-11-03

Enhancements

Deployment flows in the Manage tab now include additional details, such as the name of the user who requested the deployment, the user who approved it, the deployed date, and the list of data hosts. See Deploy an application configuration.

A new, revamped NLU modeling best practices topic describes best practices for creating high-quality NLU models, including tips for designing the model, generating training data, and evaluating and improving NLU accuracy.

Documentation updates

See the following change logs for other updates:

2021 October

2021-10-27

Enhancement

In Mix.dialog, the Validation panel lets you navigate more efficiently to areas that need attention, in the Node properties pane or Messages resource panel, from error and warning messages. These areas are now outlined in red (error) or orange (warning).

Documentation updates

See the following change logs:

2021-10-14

Enhancement

Mix.dialog has new output formatting options for TTS and Audio Script messages. Mainly, it is now possible to apply TTS formatting in the Audio Script modality for variables and entities that support output formatting, and to add SSML tags to format string-type entities and variables in both the TTS and Audio Script modalities.

Documentation updates

See the following change logs for more information on this enhancement:

2021 September

2021-09-29

Feature highlights

In compliance with U.S. and international laws and in accordance with Nuance’s Child Data Policy (COPPA), the workflow for creating builds has changed. Nuance’s policy is related to online services that are subject to applicable child data privacy laws, such as, but not limited to, the Children’s Online Privacy Protection Act (COPPA) and Article 8 of the General Data Protection Regulation (GDPR). Nuance’s Child Data Policy prohibits providing hosted services to websites or online services that are primarily directed towards children under the age of 16. For more information see Children's data privacy legal acknowledgement.

It is now possible to assign a reporting property to simple variables in Mix.dialog, to facilitate the generation of reports based on event logs from the Dialog service. This new property allows you to flag variables that are relevant for reporting, and specify if they should be interpreted as dimensions, attributes or metrics. The Dialog service takes care of logging the reporting metadata and values, via the reporting-vars event, whenever they are set or updated at runtime.

A new predefined variable, ExternalResourceReferences, is available in all Mix.dialog projects, to support referencing external NLU and ASR resources. At runtime, these resources augment and improve recognition and interpretation results. This includes:

See also Referencing compiled resources in the DLGaaS documentation.

In Mix.dialog, you can define latency messages to be displayed or played while data is being retrieved at data access nodes. Note that, at runtime, after the client application receives a continue action with a latency message from the Dialog service, it must respond with an ExecuteRequest to continue the flow. See Data access actions and Continue actions for more information.

Beta feature release

The Mix.dialog user interface is now available in Japanese. See Change the user interface language.

Enhancements

The Mix.dialog note editor and the node description field are more spacious and easier to use.

It is now possible to add newlines in your Rich Text messages, notes, and node descriptions in Mix.dialog, by using the keyboard shortcut Shift+Enter (or Shift+Return). Note that this adds the \n sequence in the internal representation of your messages. Therefore, don't insert line breaks in TTS and Audio Script messages.

Known issues

(Mix.dialog) In Firefox inserting a line break, in a Rich Text message, a note, or a node description, sometimes generates an additional line break. Workaround: Delete any unwanted line breaks.

(Mix.nlu/Mix.dialog) After deleting an intent in Mix.nlu, stray data might remain in your dialog design, which generates warnings for intent mappers nodes when you validate your design. For example:

Workaround: (1) Export your dialog model. (2) In projectIntentMappings, look for the mapping object with the intent ID from the "Error finding intent with id..." warning. (3) Delete the unwanted mapping object. (4) Import the amended JSON file back into your project.

Fixed issues

English (UK) dynamic concatenated audio support: In dialog applications meant to support English (UK), dynamic Audio Script messages with output formatting generate an error at runtime.

In the case of client applications that support multiple channels, the Dialog service might return message information for modalities that are not applicable in the active channel. Note that if your client application is correctly configured, this change should have no impact.

Documentation updates

Feature highlight

The Mix.nlu Discover tab now provides more fine-grained controls to select and filter retrieved application data. You can now select a date range, and filter samples by recognized intents and entities, confidence score range, and the character count range. In addition, you can seamlessly add data back into your model as additional training data, and easily correct the recognized intent before you add a sample. Note that any entity corrections must be performed after adding the data to the model. See Discover what your users say for details, as well as the Mix Community Forum announcement.

2021-01-24

Fixed issues

(Mix.dialog) For question and answer nodes that collect NLU intents (and do not reference a question router node), validation generates an unwanted warning.

(Mix.dialog) For question and answer nodes that collect Boolean or yes/no entities, if there aren't any actions set in the Default section of the System Actions, and the node does not reference a question router node, this generates an unwanted warning. Validation reports: "Recognition node has no controller and defines no transition to another node in its default actions." You can safely ignore this warning.

2021-01-20

Obsolete protocols

For ASR as a Service, the v1beta1 and v1beta2 protocols have been removed from the software and the documentation, and are no longer supported.

Documentation updates

2020-12-14

Mix version: GA (3.6.0 candidate)

To mask customer information in accordance with Personally Identifiable Information (PII) standards, you can now mark entities and variables as sensitive in both Mix.nlu and Mix.dialog. At runtime sensitive data will be masked in all call logs for the application.

Note: For changes to take effect in the runtime services, you need to build a new model and deploy it to the applicable environments. Only then will the runtime services be aware of the updates and start masking the entities and/or variables.

See the following change logs for details, including other updates and improvements:

Redesign of the Question & Answer node to provide easier access to the node's properties.
