    Speech Analytics System Settings
    1. Select Identify language automatically or select individual languages.
    2. Specify minimum call length for transcription using the Transcribe calls with talk time over, sec field. Use this setting to avoid recording short calls where retaining a transcript might not be critical.
  2. Set up Keyword groups, a classified list of keywords to be highlighted in call transcripts and reports according to your business needs. In the Voiso navigation bar, navigate to Administration > Keyword groups.
    1. Refer to Managing Keyword groups for information about using the Keyword groups page.
    2. Refer to Adding keyword groups for information about adding new keyword groups, including importing a CSV file of your custom keywords.
    3. Refer to Deleting keyword groups for information about deleting keyword groups.
  3. Optionally, you can replicate call recordings and analyzed transcripts to your Amazon S3 bucket for further analysis outside of Voiso. Refer to Call Recordings Replication to S3.
  4. Review keyword use in your contact center.
    1. Use the Call transcription in the CDR to quickly find highlighted keywords.
    2. Use the Keyword counter and Agent List widgets in the Real-time dashboard to view current trends in keyword use.
    3. Use the Agent List Keyword groups option in the Historical reports to view past trends in keyword use.

Keywords and keyword groups

Speech Analytics highlights keywords in call transcripts and classifies them by keyword group so that you can easily identify keywords in a transcript and determine how well agents are complying with your business practices.

The Keyword groups feature includes five groups by default:

  • Positive (editable but cannot be deleted)
  • Negative (editable but cannot be deleted)
  • Preferred
  • Ineffective
  • Compliance

You can modify or delete the default groups according to your business needs, and also add custom keyword groups. Refer to Managing Keyword groups for more information about how to customize keyword groups for your organization.

Enabling Speech Analytics for a user

After you have enabled Speech Analytics in your contact center and created your keyword groups, enable Speech Analytics for specific users by using Security Access Groups.

Create a new security access group, follow these steps:

  1. From the Voiso main menu, navigate to Administration > Security access groups.
  2. Click Add access group.
  3. Select the privileges for the new group.
  4. To enable Speech Analytics, enable the Enable Transcriptions with Analytics.
  5. Click Save.
  6. Assign the new security access group to specific users.

Keyword compliance

The Voiso Speech analytics feature processes call audio recordings into a text transcript of the call. It then applies keyword group labeling to the text transcript, ensuring compliance with your business standards. The analyzed transcript is stored in the Call Detail Record (CDR).

Reporting

You can use the reports from the Speech Analytics feature to gauge the climate and tone of your agents' conversations with your contacts.

Keyword Groups Real-time Dashboard

Use the Real-time dashboard to monitor current keyword use by your agents and contacts. Use Historical reports to monitor past keyword use.

Use Case: Call transcript review

Reviewing call recordings to ensure compliance with your organization's standards is time-consuming for supervisors. With the transcripts produced by the Keywords and Speech analytics features, supervisors can quickly review the content of a call recording without spending time listening to the audio.

The Call Detail Record (CDR) for each analyzed call recording includes the transcript with highlighted keywords and a table displaying the count of keywords, the group they belong to, and the person who said the keywords.

Transcripts enable Supervisors to review conversations quickly, and the highlighted content permits supervisors to focus on the crucial quality elements, ensuring that calls are handled correctly.

Tip

You can specify the minimum call duration for transcription by setting the Transcribe calls with talk time over x sec option in the Speech analytics section of the System settings page.

Call transcript

The Call transcription panel is displayed at the bottom of a call detail record page after the audio clip. Click Transcript view (1) to access the call transcript. Click Table view (2) to access the keyword statistics. Click the speaker filters (3) to toggle among All, Agent, and Client information. Click the keyword filters (4) to toggle among All, Negative, Positive, and other keyword groups. Use the Search field to find specific words and phrases in the transcript.

You can replicate call transcripts to your Amazon S3 bucket for use outside of Voiso. Refer to Call Recordings Replication to S3 for information about setting up this feature.

Important

Transcripts uploaded to AWS S3 do not include any analysis data. Only the raw transcript is uploaded. To leverage the analysis capabilites, use the CDR Call transcription feature transcription and table views.

Use Case: Monitoring compliance

The Compliance keyword group contains words and phrases used in conversations that might indicate a risk to your organization. By highlighting the use of these words in a conversation, the Speech Analytics feature can help you to mitigate risk rapidly.

You can use the Real-time dashboard to monitor compliance while monitoring your agent's activity.

When you set up the Agent List widget, select Compliance in the Analytics tab to include a count of your agents' use of compliance terms.

The Compliance column is added to the Agent List widget. When the Speech Analytics completes an analysis of a call recording it increments the count of compliance terms in the Agent List widget.
