Voice Tracking with Sennheiser TCC2
2. Solution overview
Voice Tracking PTZ Control solution provides automatic camera control based on vector information provided by
Sennheiser TCC2 ceiling microphone array.

The basic principle of operation is querying the direction information of the sound source from the TCC2 microphone.
According to the vector information coming from the microphone the algorithm of the LARA configuration tries to
choose a camera preset from the previously stored ones which fits the best. If any of the stored vector information
matches the current vector the corresponding preset is recalled from the camera, aiming it to the person speaking.
The Sennheiser TCC2 unit includes 28 omnidirectional microphone capsules. This enables the microphone to
determine the currently speaking person’s position in the meeting room at any time. It is indicated on the vector
panel of the LARA configuration, helping integrators in the configuration process.
Setting up the camera preset can be done using the PTZ Camera Control panel of the LARA configuration:
