8. If the operator being edited already includes voice attributes, proceed to step 9 and edit the available fields.

If the operator profile does NOT have voice attributes and you want to include them in this profile, check the "Voice attributes" box to enable further options regarding voice parameters as well as a new tab - the "Advanced Voice Settings" tab.

10. If required, continue to the "Advanced Voice Settings" tab.

If you have concluded your edition, proceed to step 12.

11. Edit the available fields according to your requirements:

Technical Profile

Maintain or select a different Technical Voice Profile. The drop-down list displays the files added in the "Voice" tab included in the "Site Details" page. See "Site Details" - Voice tab.

Voice Type

Maintain or select another voice type from the drop-down list (Auto, Neutral, Male, Female or Child). For most cases, the default value (Auto) is preferred, but you can select a more appropriate voice type for the operator. Defining the wrong voice type for the operator will affect speech recognition quality.

Speech Sensitivity

Maintain or define new speech sensitivity value for the voice devices.(available values from -3 to +3). For most cases, the default value (Auto)is the preferred choice.

When defining a new value, consider the following:

•	A high speech sensitivity helps detect a low energy speech (operator with a soft voice) but it increases the risk of noise processing.

•	A low speech sensitivity reduces the risk of noise processing but requires a high energy speech (operator must speak loud and clear) for a good detection.

Ex: For operators with a loud and clear voice, define a speech sensitivity value of -1 or -2.

Note that some words start with low energy (ex: words with an initial "sh" sound) which means they might not be detected if the speech sensitivity value is too low.

Recognizer Sensitivity

Maintain the value or define another Recognizer Sensitivity value (available values from -3 to +3) in the corresponding box.

When altering the Recognizer Sensitivity value, consider the following:

•	The operator's speech level (a good speech -high energy/loud and clear word pronunciation OR a poor speech -low energy and bad word pronunciation).

•	The operator's environment and possible interference from background noise.

Ex: Too low recognizer sensitivity dismisses background noise but does NOT accept an operator's "poor" speech.

Possible settings based on general considerations:

Operator Speech Output	Recognizer Sensitivity Value
People who do NOT complain about repetitions	0
non-native speakers	+1
native speakers	-1

Fine tuning suggestions:

Operator Complaints

Value Corrections

For operators that are fine with recognition (low repetition) but have with complaints about insertion.

Reduce the Recognizer Sensitivity value: from -1 to -3.

Reduce Speech Sensitivity (a -1 or -2 value) unless the operator has a low energy speech.

For operators with complaints about repetition.

Increase the Recognizer Sensitivity value: from +1 to +2.

Increase Speech Sensitivity (a +1 or +2 value), if the operator has a low energy speech.

Log Level

Maintain or enter a new value. (1 = enabled, 0 = disabled. The other levels are not supported, at the moment.)

Log until

Maintain the date or click and select another end date for log generating.

Adaptation Status

This field is NOT editable. Its content depends on the optional voice adaptation performed by the operator. See The Adaptation Process.

Adaptation Date

This field is NOT editable. Its content depends on the optional voice adaptation performed by the operator. See The Adaptation Process.

12. Once you have executed all the required modifications, click to apply all the changes.

To change an Operator Profile's Status

There are 3 available operator profile statuses:

Enabled: The operator is active and able to login.

Disabled: The operator is inactive and unable to login.

Locked: Operationally speaking, this status is the same as the "Disabled" status - the operator cannot login to the site. The customer can use this status from an operator management point of view, depending on the site's internal organization/operations.

Step-by-step

1. In the selected operator's "Operator Details" page, click .

Operator Details Page Change Status

2. Select the required option from the drop-down list. Depending on the operator's current status (enabled/disabled/locked), the available options will be the remaining ones.

Ex: The operator "Edward Black" currently has an "Enabled" status. Therefore, the available options for status change are "Disabled" and "Locked".

3. Click to conclude the changing status operation.

The new status is displayed in the "Status" field, to the left.

The Adaptation Process

In order to improve voice recognition performance, you can use an adaptation process which will analyze and store operator pronunciation characteristics (accent). This adaptation is very useful for non-native speakers, speakers with accents or special voice characteristics because it improves overall recognition performance for that particular operator.

When the operator logs in, the device communicates with the account to verify if no adaptation has already been performed. If no adaptation data exists, an automatic procedure is set on the device to execute the adaptation process.

The adaptation process consists of data collection (the operator repeating key words and expressions that will be used to interact with the application in the voice device) and accent analysis (the resulting file stores that operator's pronunciation characteristics which is analyzed).

The adaptation's objective is to improve the voice device's recognition of that operator.

Once the operator has executed an adaptation, you can reset said adaptation, meaning, you can delete it. To do so, follow these steps:

To reset an Operator's Adaptation

Step-by-step

Keep in mind that there are two locations to execute this operation:

1. In the "Operators" page OR in the selected operator's "Operator Details" page (in which case, the operator must NOT be logged in).

2. If the reset operation is executed in the "Operators" page, select the operator(s) to have the adaptation reset by checking the corresponding .

If you are executing the "reset adaptation" in "Operator Details" page, continue to step 3.

3. Click .

Reset Adaptation Confirmation

4. Click to conclude the operation.

At this point, the disappears from the header of the "Operator Details" page and the corresponding information in the "Advanced Voice Settings tab ("Adaptation Status" and Adaptation Date" fields) disappears.

When the operator logs in again, he will be asked to execute a new adaptation.
