Dynamic Audio

The Dynamic Audio node allows a textual value to be read out to a caller as spoken words, using a predefined format in either a male or female voice. Date, Time and Currencies can be read out as English words and numerical values as conversational words. Alphanumeric characters can be read out individually either verbatim or phonetically.

Branch Name	Mandatory	Description
Continue	No	Taken when the audio playback has completed.
Failed	No	Taken if the Value could not be interpreted using the configured format.

There are four fields to configure within this node: Gender - Choose from Male or Female voice. Input Value - This is where the data to be read out is held. Interpret As - This informs the system what type of data is in the Input Value Spoken Format - This is where you specify the way you want the Input Value read out.

The Input Value Property

The maximum length of the Input Value property is 32 characters including spaces. The input value can either be a literal value or a Custom Service Variable. It is important to set the input value property to a value that can be interpreted using the format you have selected. The Interpret As and Spoken Format properties determine how the value will be interpreted and played back to the caller. If you have selected the input value to be interpreted as a Date, the textual value must represent a valid date in the British format. The validation of the value does not take place in the Service Designer when saving the Service so it is possible to enter unexpected values and characters for a selected format. The interpretation and sanitation of the input value takes place during the call. Before the input value is interpreted it is first sanitized, removing any characters that are not in the expected characters for the selected format (see table below). If it is still not possible to playback the input value according to the configured format, the call flow will continue down the Failed branch.

Expected Characters

The following tables provides the expected characters for the input value property. Any character not included in this table will be removed from the input value before it is interpreted.

Interpret As	Expected Characters
Alpha Numeric	A to Z 0 to 9 "Space"	When the interpreter encounters a "Space", a 0.2 second pause will be inserted for each space into the audio playback. Any special characters will be removed, for example if the value contains a decimal point, "15.96", it will become "1596" and be played back according to the selected format. The largest number value that can be played back using the conversational format is 999,999,999,999
Date	A to Z 0 to 9 "Space" "/" ":" "-"	Date values are expected in British date format dd/mm/yyyy or dd-mm-yyyy but can also be in long date format. "01 January 2020", "01 Jan 2020", "01/01/2020", "01-Jan-2020" are all acceptable. It is also acceptable but not required for the date value to also include the time. The time part of the value will be ignored by the interpreter.
Time	A to Z 0 to 9 "Space" "/" ":" "."	Times are expected in hh:mm or hh.mm and can be in 12 or 24 hour format. The value can also contain the seconds (hh:mm:ss) but the seconds will be ignored by the interpreter. Values such as "15:30", "3:30pm", "03:30am", "03.30 p.m" are acceptable. Time Zone information is not currently supported. The interpreter will ignore any time zone information, also if a Time Zone is specified in the Start node this will be ignored. The value can also include a date but it not required. The date part of the value will be ignored by the interpreter.
Currency	0 to 9 "."	Integer or decimal values are acceptable. Values with more than two decimal places will be rounded to two. "23.123" would become "23.12" "23.126" would become "23.13" The largest decimal value that can be played back is 999,999,999,999.99
