Permissions

Speech Recognition

This module is licensed separately from Quality Management. It is necessary to have the required license to use this feature. It is also necessary that you have the required role assigned by your administrator: VIEW_TRANSCRIPTION.

Users without this role will see a message displayed in the Conversation Explorer Details Pane that states: "No acoustic & emotion available" or "No transcription available".

Speech Tags and Phrases

To modify Speech Tags and Phrases it is necessary to have the required role assigned by your administrator: SPEEECHREC_ADMIN.

Emotion Detection

This feature is only supported for selected languages.

Emotion detection is only available for installations that have a valid Speech Recognition license and for conversations that contain a transcript.

Emotion detection is currently only available for the English Language. We are actively working on this enhancement.

The emotion detection feature combines acoustic features and word sentiment scores of the transcription files to determine emotion. Emotion detection is not influenced by customer-defined speech tags, as the speech tags are applied to the transcription after it has been analyzed for emotion (refer to the dedicated page for information on how to configure Speech Tags and Phrases).

Emotion is displayed in the system in two different ways:

Participant emotion - is displayed in the Conversation Explorer Details pane.
Emotion of individual lines in the transcript – Emotion for each transcribed sentence is displayed alongside the transcript.

Participant emotion

The average emotion of the participant at the end of the conversation is extracted from the transcription and then displayed within the Conversation Explorer Details Pane. The emotion shown in the details pane can be improving, positive, neutral, negative or worsening. This is the overall emotion (of one party) during the last segment they were participating in. E.g. This is the emotion of the speaker when they left the call.

Emotion of individual lines in the transcript

Emotion for each transcribed sentence is displayed alongside the transcript within the Details Pane.

To view Emotion:

Open the Conversation Explorer and select a conversation that contains a transcript.
Expand the Details Pane.
An emoticon will display alongside the transcript.
The emotion is shown for each transcription utterance (sentence). The emotion detection feature combines acoustic features and word sentiment scores to determine the emotion of each individual sentence. The emotion displayed within the transcript can be Mostly Positive, Positive, Neutral, Negative, Mostly Negative.

This is also described in the documentation for the Conversation Explorer.

Phrase Detection

Speech tags and phrases are defined by users (refer to the dedicated page for information on how to configure Speech Tags and Phrases). The system scans new media (transcriptions) and matches the defined speech tags and phrases with words or phrases in the transcript. The detected phrases are then saved to the database and are displayed to users on the Conversation Explorer screen. A more detailed description of the process is described in the section How Does Phrase Detection Work (in Brief) on the page dedicated to Speech Tags and Phrases.

Limitations

The recording server must be set to output WAV files!
Integrations that generate only mono audio recordings, such as MS Teams © Recording, are supported. Two identical audio waveforms are displayed in the Interaction Player, one for each channel. This is expected behavior.
Conference participants are not identified by the speech recognition software. The current implementation can only detect 2 participants in the call.
Individual participants are not recognized in mono recordings. We recommend that you capture stereo audio recordings whenever possible.

Redaction of Sensitive Data

This feature is only supported for selected languages.

Eleveo takes personal data seriously and supports the redaction of sensitive data from transcriptions. The redaction of credit card data and other sensitive numbers is enabled by default (installation dependent) when the solution is first configured.
Any redacted information is shown as #### hashtags in the transcription so that viewers can clearly see that something was hidden.

If enabled, the Transcription engine will redact sensitive numeric values from transcription results. By default, sensitive numbers are any string of numeric digits that do not fit into an allowable pattern.

Patterns that are allowed by default are the following:

Ordinals (1^st, 2^nd, etc.)
Percentages
Clock times (12:57 PM, etc.)
Monetary amounts
Floating point numbers with 4 or fewer digits (12.47 GB, etc.)

Transcription Improvement/Tuning

This feature is only supported for specific language packs.

Administrators of your installation can upload industry-specific terminology to improve the transcription accuracy. Add words or phrases to the Out-of-vocabulary (OOV) dictionary to ensure that brand or product names, or industry-specific terminology is accurately transcribed.

This feature is available for Eleveo V 9.3+.

Limitations

Conference participants are not identified by the speech recognition software. The current implementation can only detect 2 participants in the call.
