| Sound Source Localization for Robot Auditory System |
| |
| Robot Auditory System |
- It is very important function for Human-Robot Interaction. It can make Robot to recognize what and where someone said.
- It mainly consists of the speech/speaker recognition and the sound source localization
|
| Research Objectives |
- Develop the Sound Source Localization method to satisfy some conditions for robot auditory system
- Localize the source in 3D spaces
- Use the minimum number of microphones for reducing the hardware requirements.
|
| The Summed GCC method |
- This is based on TDOA (Time Delay of Arrival) for localization.
- The cross correlation function to estimate the time delay is converted to the mapped GCC function to estimate the source position.
- When multi-microphones are used for localization, estimation results of all microphone pairs can be easily combined in the global coordinate.
- It is possible to localize the source in 3D spaces with only three microphones to utilize the robot platform effect, although the conventional method should have the minimum four microphones to do.
- This shows the better performance than the conventional one in the worse environment conditions, that is a bad SNR condition.
