Number

The Number voice element captures a number input from the caller. The number can be spoken or entered using the keypad. The resulting value will be stored in element data as a decimal value. The number can be negative or positive and can contain a decimal point. Using DTMF entry the number is restricted to being positive and the decimal point is entered by pressing the * key. Using speech input, the number may be spoken naturally.

Note

 
You cannot use the * character to represent a decimal point in the Number voice element, if you have defined it as a termchar in the Root Doc Settings.

Notes

inputmode

(Input Mode)

string enum

Yes

true

false

The type of entry allowed for input. Possible values are: voice | dtmf | both.

noinput_timeout

(Noinput Timeout)

string

Yes

true

true

5e

The maximum time allowed for silence or no keypress before a noinput event is thrown. Possible values are standard time designations including both a non-negative number and a time unit, for example, 3s (for seconds) or 3000ms (for milliseconds). Default = 5s.

max_noinput_count

(Number Max NoInput Count)

int ≥ 0

Yes

true

true

3

The maximum number of noinput events allowed during number input capture. 0 = infinite noinputs allowed.

max_nomatch_count

(Number Max NoMatch Count)

int ≥ 0

Yes

true

true

3

The maximum number of nomatch events allowed during number input capture. 0 = infinite nomatches allowed.

number_confidence_level

(Number Confidence Level)

decimal (0.0 – 1.0)

Yes

true

true

0.40

The confidence level threshold to use during number capture.

modal

(Disable Hotlinks)

boolean

Yes

true

true

false

Whether or not to temporarily disable all hotlink grammars (global or local) and universal grammars. If set to true, only the grammars of the current Number element will be enabled for the duration of the element. Otherwise all active grammars will be enabled.

secure_logging

(Secure Logging)

boolean

Yes

true

true

false

If set to true, user DTMF input for the element is considered secure and the attributes utterance, interpretation, value, nbestUtteranceX and nbestInterpretationX are masked in VXML server logs. The format used to render secure element attributes is to add a _secureLogging suffix. For example nbestUtterance1_secureLogging,*****.

maxnbest

(Maxnbest)

int ≥ 1

Yes

true

true

1

The maximum number of speech recognition results that can be generated per voice input.

dtmf_overlay

(DTMF Overlay)

Boolean

Yes

true

true

false

Setting this property to true will enable the generation of random DTMF digits tone at random duration while DTMF recognition is in progress.

Note

 

dtmf_overlaysupports only the following VoiceXML Gateways, and one of these options must be selected before creating or deploying the Call Studio application.

  • Cisco DTMF

  • VoiceXML 2.1 Cisco DTMF

dtmf_overlay_interval

(DTMF Overlay Interval)

String

Yes

true

true

1000ms

Time Interval (in ms) between the generation of two DTMF tones. The interval is a random number that is +/-25% of the duration that is mentioned. For example, if the duration mentioned is 1000ms, the interval will be between between 750ms and 1250ms.

Note

 

The duration mentioned must be between 500ms (minimum) and 2000ms (maximum).

Element Data

Name

Type

Notes

Value

string

The number captured and stored as a whole or decimal number with an optional minus sign.

value_confidence

float

This is the confidence value of the captured utterance. When n-best recognition is enabled, this stores the confidence score of the top hypothesis in the n-best list.

nbestLength

int ≥ 1

This stores the number of n-best hypotheses generated by the speech engine.

nbestUtterance1

nbestUtterance2

nbestUtteranceX

string

This set of element data stores the captured n-best utterances. While the maximum number of nbestUtteranceX values is equal to the maxnbest setting value, the actual number of these values available is determined by speech recognition at runtime, where nbestUtterance1 holds the utterance of the top hypothesis in the n-best list and nbestUtteranceX holds the utterance of the last hypothesis.

nbestInterpretation1

nbestInterpretation2

nbestInterpretationX

string

This set of element data stores the interpretations of captured n-best utterances. While the maximum number of nbestInterpretationX values is equal to the maxnbest setting value, the actual number of these values available is determined by speech recognition at runtime, where nbestInterpretation1 holds the interpretation of the top hypothesis in the n-best list and nbestInterpretationX holds the interpretation of the last hypothesis.

nbestConfidence1

nbestConfidence2

nbestConfidenceX

float

This set of element data stores the confidence scores of captured n-best utterances. While the maximum number of nbestConfidenceX values is equal to the maxnbest setting value, the actual number of these values available is determined by speech recognition at runtime, where nbestConfidence1 holds the confidence score of the top hypothesis in the n-best list and nbestConfidenceX holds the confidence score of the last hypothesis.

nbestInputmode1

nbestInputmode2

nbestInputmodeX

string

This set of element data stores the input modes of captured n-best utterances.

Exit States

Name

Notes

max_nomatch

The maximum number of nomatch events has occurred. If the nomatch max count is 0, this exit state will never occur.

max_noinput

The maximum number of noinput events has occurred. If the noinput max count is 0, this exit state will never occur.

done

The number capture was completed.


Note


If the number to be captured is a positive whole number and the input is via DTMF, the number can be entered using this voice element or the Digits voice element.
