Speaker Diarization

Speaker Diarization is the process of partitioning audio input streams into homogenous segments according to the speaker identity. This enables the separation of the speech of individual speakers during a broadcast, meeting or even in a crowd and facilitates the recognition of individual speakers. Furthermore, additional tags including male/female and approximate age can be added.

Speaker Recognition

Anonymous The recognition of a speaker can be based on identification of a voice which is heard repeatedly. This is performed on an anonymous basis and a number will be assigned to the voice of a speaker.

Recognition of a specific person The recognition of a specific speaker is based on the identification of a voice which is stored in a database. This is performed using a previously recorded voice and the name of a speaker is assigned to the voice.

GVC Emo Analysis Service

Only emotions, no identification GVC Emo Analysis Service only applies speaker recognition as a tool to separate voices and to recognize the voice of a person who is speaking repeatedly, but without the aim of recognition of a specific person. This may be applied to assess the individual emotions of various speakers during a broadcast, in a meeting or even in a larger crowd.

GVC Privacy Security

No storage of data 

GVC Privacy Security means that GVC guarantees that no data will be stored on our servers. The real time analysis is performed on speech data which is sent to our server and is analyzed instantly without any data storage. The analysis is reported back in a split second and no source data is stored on the server. This approach requires a rapid and stable internet connection.

CPU Capacity

The real time emotion analysis requires a large CPU calculation capacity. GVC has established this capacity.

Test Phase

Diarization is in an advanced testing phase.

Crowd – Team Emo Analysis

Under pressure or in an unknown environment, people may respond based on the primary or real emotions. At an important business meeting, a job interview or in large groups, you may not always get what you see; people may perform poorly in those circumstances.

Crowd – Team Emo Analysis is one of the many useful applications of the software and technology developed by GVC. One of the core elements in the Emo Analysis of Crowds and in Team meetings is the Diarization.
This enables the distinction between various voices of different individuals and enables a sophisticated analysis of the emotions of a crowd or in a meeting.

Team Meetings

The Crowd – Team Emo Analysis offers the opportunity to measure and display the emotions of each team member separately during a Team Meeting. In addition, the GVC Emo Analysis Service also shows, by the total mood-line in the dashboard or display, the evolution of the atmosphere of the discussions, from the beginning of the meeting, evolving during the interactions and the final outcome at the end. In this way, concrete and visible to all participants, it can be demonstrated, whether, for example, a meeting started in a suboptimal atmosphere, and finally resulted in positive conclusions in a good atmosphere.

Management Tool

So it is an extraordinary Management Tool, which may provide feedback on the emotions of each participant in the meeting and may therefore be a valuable tool to assess the status of the team.

Radio and TV interview programs

When holding an interview with a larger group, the emotion of each participant in the discussion can be analyzed – based on the diarization – even if they talk through each other, which is the normal characteristic of a discussion.

Crowd Emo Analysis Service

Crowds are not about individual emotions, but about the emotions of an entire group. That is clearly visible through analysis of the average mood of the group. This is also the case at Pop Concerts, Festivals and all kinds of Events.
It’s a Gauge of mood. The measurement of the feeling temperature. Effectively this may provide a tool for the authorities to intervene if the overall mood of the crowd evolves in an aggressive attitude, which needs to be controlled to prevent an escalation.
