Virtual Assistants Service Settings

Voice transcription and live captioning.

INC Beta Feature

This feature is in BETA status. Functionality, design and scope may still change significantly over time.

🤔Why should I use transcription? Transcribing customer calls improves quality assurance and increases the efficiency of call processing, for example making it easier to summarize past customer interactions and possibly transfer them to a CRM system for easier search and later analysis.

INC Azure Billing Transcription

AZURE BILLING

The usage of the Transcription feature will cause additional monthly ACS costs. The costs are determined by Microsoft. Also see https://azure.microsoft.com/en-us/pricing/details/cognitive-services/speech-services/.

  • Before enabling the Transcription feature, get in touch with your Luware Customer Success specialist to discuss terms, usage scenarios and necessary setup procedures.
  • Please note that Nimbus and Transcription support does not cover pricing discussions or make recommendations based on Microsoft Azure infrastructure.
 

Virtual Assistant transcription modes

Virtual Assistant works in two modes:

  • Live Captioning is performed during the ongoing call and displayed on the My Sessions page.
  • Voice Transcription is triggered when the call ends using the Nimbus Power Automate Connector. You can write the outputs to any target, e.g. into a Teams Message or Mail. → more on this below.

🔎This feature supports various regions as specified by Microsoft AI services. Allows to detect and support up to 4 languages per API configuration.

Voice Transcription

Once a call has ended, a voice transcription from Microsoft is generated. You can show this in My Sessions to your users or retrieve the transcribed text via Nimbus Power Automate Connector by leveraging the Trigger Event "When the virtual user assistant has an update".

✅ After setting up a Speech Recognizer in the Configuration you can select it here. Refer to Use Case - Setting Up Transcription for detailed instructions.

✅ Follow-up steps: 

 

Live Captioning

After enabling Live Captioning, a “Live Captioning”  widget can be enabled in the Extensions Service Settings. Nimbus users will see this interaction as described on the Transcription feature page.

✅ Enabling “Voice Transcription” and setting up a Speech Recognizer in the Configuration is mandatory to use "Live Captioning". This is necessary so that the right language engine is used for voice detection.

💡Good to know: 

  • When the feature is disabled or unavailable (e.g. throttling, missing settings or service impediments on Microsoft side) info messages are shown in the frontend UI widget. Nimbus task handling and user-customer interactions themselves are not affected by this and will continue normally.
  • Only the transcription between the current User and the Customer is kept, no third parties. → Also refer to the Known Limitations chapter below.

✅ Follow-up steps: 

  • Live Captioning is also used to show a Live Caption widget with historical (concluded) sessions, enabled via Extensions Service Settings > Widgets.
 

Known Limitations

INC Transcription Limitations

KNOWN TRANSCRIPTION LIMITATIONS

  • MS Teams-native transfers during a transcription session. In a group call (with customer, user and Nimbus bots), the Teams client currently cannot automatically distinguish between the Nimbus transcription bot and calling customer. 

Workaround: If you want to transfer a session with active transcription enabled, you need to use Attendant Console as it allows Nimbus to steer all group participants individually, e.g. in a Attendant - Safe Transfer or scenario.


Supervision - by design (not a limitation): As long as Supervisors remain in Listen or Whisper mode during a conversation, their voice is not being transcribed. Only during ”Barge In" they are part of the conversation and transcription is active.
