Language Operators turn transcripts into structured information using a variety of techniques, including machine learning. Pre-built Language Operators (PBLOs) have been created by Twilio. They are trained across a wide swath of customer data and typically map to data types that are agnostic to use-case or industry. PBLOs can’t be modified or made more specific.
The following PBLOs are currently available for use.

Agent Introduction
Action: Phrase matching
The Agent Introduction operator determines if an agent introduced themselves on a call.
The Agent Introduction operator doesn’t detect a specific type of introduction. If you want to determine whether or not an agent introduced themselves in a specific way, we recommend that you create a Literal Spot operator that looks for the introductions that you are attempting to find.
| Class | Description |
true |
The operator spotted an introduction |
false |
The operator did not spot an introduction |
Escalation Request
Action: Phrase matching
The Escalation Request operator determines whether or not a customer requested an escalation during a call. It captures events like a customer asking to speak to a manager or a supervisor.
| Class | Description |
true |
The operator spotted an escalation request |
false |
The operator did not spot an escalation request |
Outbound Call Disposition
Action: Classify
The Outbound Call Disposition operator determines the outcome of an outbound call. It is is geared toward customers who are running outbound dialing campaigns and have a set of outcomes that are focused on campaign list management.
| Class | Description |
GhostCall |
The call was picked up and one participant does not provide any audio |
IVR |
The call was picked up by an automated Interactive Voice Response (IVR) system |
NoContent |
There was no audio during the call |
Ordinary |
The call was picked up by a human and proceeded normally |
StopContactingMe |
The call was picked up by a human who requested to be removed from a campaign list or requested to be placed on a do-not-call list |
Voicemail |
The call was picked up by a voicemail system |
WrongNumber |
The call was picked up by a human who indicated that it was a wrong number |
Recording Disclosure
Action: Phrase matching
The Recording Disclosure operator determines whether or not an agent notified the customer that the call was being recorded. Typically, this operator is used on outbound calls where it doesn’t make for a good customer experience if you use a recording to announce that the call is being recorded before a human agent greets the customer.
The Recording Disclosure operator doesn’t match a specific type of recording disclosure. If you have a specific disclosure that you want to ensure that agents use, we recommend creating a Literal Spot operator to match the required phrasing.
| Class | Description |
true |
The operator spotted a participant mentioning that the call was being recorded |
false |
The operator did not spot a participant mentioning that the call was being recorded |
Voicemail Detection
Action: Classify
The Voicemail Detection operator determines whether or not a call went to voicemail. It is geared towards customers who are running outbound dialing campaigns and want to use the results to determine whether to call a specific customer back, and to assess the best time to make that call.
Unlike the Outbound Call Disposition operator, the Voicemail Detection operator only indicates whether a call was handed to a voicemail system. It does not use acoustic features to determine whether or not the call was actually picked up by the voicemail system.
| Class | Description |
voicemail |
The call was picked up by a voicemail system |
not_voicemail |
The call was not picked up by a voicemail system |
Unavailable Party Detector
Action: Classify
The Unavailable Party Detector operator determines whether or not the called party is unavailable and the call was unanswered. It is geared towards customers who are running outbound dialing campaigns and want to use the results to determine whether to call a specific customer back, and to assess the best time to make that call.
