Members

static, readonly displayTypeName :string

Returns the display type name string 'ArchTtsEngine'.

static, readonly isArchTtsEngine :boolean

Returns true indicating that this is an ArchTtsEngine instance.

readonly id :string

The identifier string for this object.

Inherited From:

• ArchBaseCoreObjectWithId#id

readonly idMayBeBlank :string

Returns whether or not the id property may be blank or undefined for this object. For example, the returned settings from ArchMenu#settingsMenu will have a blank identifier along with the settings returned from ArchMenu#settingsSpeechRec. Note that this is an extremely rare case.

Inherited From:

• ArchBaseCoreObjectWithId#idMayBeBlank

See:

• ArchBaseCoreObjectWithId#id

readonly isArchBaseCoreObject :boolean

Returns true indicating that this is an ArchBaseCoreObject instance.

Inherited From:

• ArchBaseCoreObject#isArchBaseCoreObject

readonly isSecure :boolean

Returns whether or not this text to speech engine is secure.

readonly logStr :string

A string suitable for logging

Overrides:

• ArchBaseCoreObjectWithId#logStr

readonly logStrTypeOnly :string

This is a string suitable for logging information about this object where it's just the object's type. This is normally used when logging errors that occur in constructor parameter checking because the scripting object isn't set up and the normal logging str contents wouldn't be set up.

Inherited From:

• ArchBaseObject#logStrTypeOnly

readonly name :string

The name of this text to speech engine.

Methods

getDefaultVoiceForLanguage(archLanguage) → {ArchTtsVoice}

Gets the default voice configured on this text to speech engine for a specified language. If there is no default voice specified for this engine, nothing is returned.

Parameters:

Name	Type	Description
archLanguage	ArchLanguage	the language for which the default voice should be retrieved.

Returns:

ArchTtsVoice -

the default voice for the language. If there is no default voice for this language, this function will return nothing.

getLanguageSupport(archLanguage) → {string}

Returns the language support available for this text to speech engine. Return values are: exact, languageOnly, and none.

exact: Both the text to speech engine has an exact match for the supplied language. languageOnly: The text to speech engine supports the supplied language by language only and not by region. For example, if a TTS engine / voices supported “en-ie” and the ArchLanguage with the tag “en-us” was passed in, this is a language only match because “en” is supported but “ie” does not match “us”. none: The text to speech engine does not support the language. For example, when asked if the engine supports the “es-us” ArchLanguage and it only supported “en-us” and “pt-br”, then this would return “none”.

Parameters:

Name	Type	Description
archLanguage	ArchLanguage	the language for which the default voice should be retrieved.

Returns:

string

getSupportedVoiceLanguages() → {Array.<ArchLanguage>}

Returns a unique ArchLanguage[] that are supported for this text to speech engine.

Returns:

Array.<ArchLanguage>

getVoiceById(voiceId) → {ArchTtsVoice}

Gets a text to speech voice for this engine by its voice identifier. If not found, nothing is returned.

Parameters:

Name	Type	Description
voiceId	string	the identifier of the voice to retrieve. This should be a non-blank string.

Throws:

If the voiceId string is undefined, null or a blank string, this method will throw.

Returns:

ArchTtsVoice

getVoiceByName(voiceName) → {ArchTtsVoice}

Gets a text to speech voice for this engine by its voice name. If not found, nothing is returned.

Parameters:

Name	Type	Description
voiceName	string	the name of the voice to retrieve. The name is looked up case insensitively.

Throws:

If the voiceName string is unspecified, null or a blank string this method will throw.

Returns:

ArchTtsVoice

getVoicesForLanguage(archLanguage) → {Array.<ArchTtsVoice>}

Gets all available voices on this text to speech engine for a specified language.

Parameters:

Name	Type	Description
archLanguage	ArchLanguage	the language for which supported voices should be retrieved.

Returns:

Array.<ArchTtsVoice> -

the voices that support the language. If no voices on this engine support the specified language, an empty array will be returned.

traverse(callbackFunction, traverseFilteropt) → {number}

This method iterates over this object and ArchBaseCoreObject instances within it. For each object it will call the ArchBaseObject#isFilterMatch method with a filter and call the supplied callback function if isMatch returns true. The callback will be passed an ArchTraverseInfo with details about the match such as the match object itself along with current contextual information such as the object hierarchy for the match object relative to the object on which this traverse call is being made.

The traverse filter is one which you can create by calling ArchFactoryFilters#createFilterObject and then add desired clauses or clause containers to it. If not specified, this function will use a default filter.

Here is an example that does a simple flow traversal using the default filter and logs information about objects in the callback from the traverse object that's passed back:

archInboundCallFlow.traverse(function(traverseInfo) {
   archLogging.logNote('  Object     : ' + traverseInfo.matchObject.logStr);
   archLogging.logNote('    Hierarchy: ' + traverseInfo.context.hierarchyStr);
});

This might be enough for most uses and you can check various aspects about the object in the callback such as "is this an Architect action?" by seeing if traverseInfo.matchObject.isArchBaseAction is true. You can specify a filter for the traversal code to use as well and only have it call your callback when the object's ArchBaseCoreObject#isFilterMatch method returns true for the filter. Here's an example that creates a filter for callbacks on any type of transfer action, any decision action or objects whose name property case insensitively matches the word 'foo'. While this could all be done with one property callback clause the example will use multiple clauses for the sake of simplicity:

const myTraverseFilter = filterFactory.createFilterObject(archEnums.FILTER_CONTAINER_OPERATORS.or);
myTraverseFilter.addClausePropertyValueEquals('isArchBaseActionTransfer', true);
myTraverseFilter.addClausePropertyValueEquals('isArchActionDecision',     true);
myTraverseFilter.addClausePropertyCallback('name', function(propValue, archContainingObject, propName) {
      // We fully spelled out the function signature above but archContainingObject and propName are
      // not needed in this case.  The archContainingObject is the object that contains the
      // property and propName is the property name itself.  We pass in propName because the same
      // function could be used for multiple property callback clauses.
      // Remember to return a boolean true, false or undefined from ths callback.  :)
      return propValue && propValue.toLowerCase() === 'foo';
});
archTask.traverse(function(traverseContext) {
   // You will only be called back here for ArchBaseCoreObject instances that
   // have the isArchBaseActionTransfer or isArchActionDecision property values equal to true.
}, myTraverseFilter);

If you supply a filter with no clauses, this tells the traverse method to call the supplied callback function for every ArchBaseCoreObject it traverses.

If you want traversal itself to stop after a callback, simply return boolean false from the callback function you supply to the traverse call.

The traverse method does not process deprecated property names such as orgId, orgName or languageSettings. Additionally it does not traverse in to properties that would "jump out" of the current traversal. An example of this would be if the code was traversing an ArchActionJumpToMenu action that it would not start traversing in to the menu that it jumps to. Another example would be a ArchActionChangeState action where it would not traverse in to the target state of the action. This also means traversal does not traverse in to the ArchBaseValue#flowLevelDefault property.

And lastly, as Scripting evolves over time with new versions, you can expect to get callbacks for new object types such as new actions or new properties on objects. As such, it's important not to assume any particular order in callbacks to keep code most compatible with traversal callbacks. Or if you use inequality checks in filter clauses remember that new "stuff" may satisfy an inequality check which may or may not be anticipated in your logic.

Note: This traverse method is a helper method and is very handy for iterating over Architect Scripting objects and their properties in a generic fashion with filtering capabilities. Obviously you can write your own custom traversal code if this implementation doesn't cut it for some reason. :)

This function returns the number of times it called the callback function.

Parameters:

Name	Type	Attributes	Default	Description
callbackFunction	callbackTraverseInfo			the callback function to call for objects that match the traverse filter.
traverseFilter	ArchFilterObject	<optional>	ArchFactoryFilters#createFilterTraverseDefault	the filter to use when performing the traversal to determine which ArchBaseCoreObject instances you wish to be called back for. If no filter is specified, this function will call ArchFactoryFilters#createFilterTraverseDefault and use that traversal default filter. The wantArchBaseValues parameter on that call is set to true.

Returns:

number
